Description
The LK 4000/5000 Series of AC-DC converters represents
a flexible range of power supplies for use in advanced
electronic systems; the LKP models are an extension with
increased output power, but optimized to 230 VAC.
Features include full power factor correction, good hold-up
time, high efficiency and reliability, low output noise, and
excellent dynamic response to load/line changes.
The converters are protected against surges and
transients occurring at the source lines. Input over- and
undervoltage lockout circuitry disables the outputs, when
the input voltage is outside of the specified range. Input
inrush current limitation is included for preventing circuit
breakers and fuses from tripping at switch-on.
All outputs are overload, open- and short-circuit proof, and
protected by a built-in suppressor diode. The outputs can
be inhibited by a logic signal applied to connector pin 18. If
the inhibit function is not used, pin 18 must be connected
with pin 14 to enable the outputs.
LED indicators display the status of the converter and
allow visual monitoring of the system at any time.
Full input to output, input to case, output to case and
output to output isolation is provided. The converters are
designed and built according to the international safety
standards IEC/EN 60950-1 2nd Ed. They have been
approved by the safety agencies TÜV and CSA (for USA
and Canada).
The case design allows operation at nominal load up to
71 °C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 71 °C, but
the case temperature must remain below 95 °C under all
conditions. However, higher output power up to 280 W is
possible depending on environmental conditions and
converter model.
An internal temperature sensor generates an inhibit signal,
which disables the outputs, when the case temperature TC
exceeds the limit. The outputs automatically recover, when

2Inrush current limiter (NTC, only models with TA min = –25 °C ) or option E
3Bulk capacitor Cb; bulk voltage approx. 370 V
Functional Description
The input voltage is fed via an input fuse, an input filter, a
rectifier, and an inrush current limiter to a boost converter.
This step-up converter provides a sinusoidal input current
(IEC/EN 61000-3-2, class D equipment) and charges the
bulk capacitor Cb to approx. 370 VDC. This capacitor
sources a single-transistor forward converter and provides
the power during the hold-up time.
The main transformer exhibits a separate secondary
winding for each output. Each generated voltage is
rectified and smoothed by the power choke and the output
filter. The control logic senses the main output voltage Vo
or Vo1 and generates, with respect to the maximum
admissible output currents, the control signal for the
switching transistor of the forward converter.
The second output of double output models is tracking to
the main output, but has its own current limiting circuit. If
the main output voltage drops due to current limitation, the
second output voltage will fall as well and vice versa.
A separate auxiliary converter generates the supply
voltages for all primary and secondary control circuits and
options.

switch-on cycle. Subsequent switch-on/off cycles increase the inrush current peak value.
4Operation with DC input voltage is not specified and not recommended.
Input Fuse and Protection
A VDR together with the input fuse and a symmetrical input
filter form an effective protection against high input
transient voltages.
A fuse mounted inside the converter in series to the phase
line protects against severe defects. A second fuse in the
neutral line may be necessary in certain applications; see
Installation Instructions.

Input Under-/Overvoltage Lockout
If the input voltage remains below approx. 65 VAC (LKP:
150 VAC) or exceeds Vi abs, an internally generated inhibit
signal disables the output(s). Do not check the overvoltage
lockout function!
If Vi is below Vi min, but above the undervoltage lockout
level, the output voltage may be below the value specified
in the tables Electrical Output Data.
Inrush Current Limitation
The models without option E incorporate an NTC resistor
in the input circuitry, which at initial turn-on reduces the
peak inrush current value by a factor of 5 to 10 to protect
connectors and switching devices against damage.
Subsequent switch-on cycles within short periods will
cause an increase of the peak inrush current value due to
the warming-up of the NTC resistor.
The inrush current peak value (initial switch-on cycle) can
be determined by following calculation:

150 – 280 Watt AC-DC Converters
Thermal Considerations
If a converter is located in free, quasi-stationary air
(convection cooling) at the indicated maximum ambient
temperature TA max (see table: Temperature specifications)
and is operated at its nominal input voltage and output
power, the temperature measured at the Measuring point
of case temperature TC (see: Mechanical Data) will approach
the indicated value TC max after the warm-up phase.
However, the relationship between TA and TC depends
heavily on the conditions of operation and integration into a
system. The thermal conditions are influenced by input
voltage, output current, airflow, and temperature of
surrounding components and surfaces. TA max is therefore,
contrary to TC max, an indicative value only.
Caution: The installer must ensure that under all operating
conditions TC remains within the limits stated in the table:
Temperature specifications.
Notes: Sufficient forced cooling or an additional heat sink
(applied to -7 or -9) models allows TA to be higher than 71 °C
(e.g., 85 °C), if TC max is not exceeded. Details are specified
in fig. 12, including -5 and -6 models.
Fig. 12
Output current derating versus temperature for -5, -6, and
-7 (equal to -9) models.
Thermal Protection
A temperature sensor generates an internal inhibit signal,
which disables the outputs, when the case temperature
exceeds TC max. The outputs automatically recover, when
the temperature drops below this limit.
Continuous operation under simultaneous extreme worst-
case conditions of the following three parameters should
be avoided: Minimum input voltage, maximum output
power, and maximum temperature.
Output Protection
Each output is protected by a suppressor diode against
overvoltage, which could occur due to a failure of the
control circuit. In such a case, the suppressor diode
becomes a short circuit. The suppressor diodes may
smooth short overvoltages resulting from dynamic load
changes, but they are not designed to withstand externally
applied overvoltages.
A short circuit at any of the two outputs will cause a
shutdown of the other output. A red LED indicates any
overload condition.
Note: Vo BR is specified in Electrical Output Data. If this
voltage is exceeded, the suppressor diode generates losses
and may become a short circuit.
Parallel or Series Connection of Converters
Single- or double-output models with equal output voltage
can be connected in parallel without any precautions using
option T (current sharing). If the T pins are interconnected,
all converters share the output current equally.
Single-output models and/or main and second outputs of
double-output models can be connected in series with any
other (similar) output.
Notes:
– Parallel connection of double-output models should always
include both, main and second output to maintain good
regulation.
– Not more than 5 converters should be connected in parallel.
– Series connection of second outputs without involving their
main outputs should be avoided, as regulation may be poor.
– Series connection of outputs totalizing more than 36 V
nominal voltage need additional measures to limit the output
to SELV (Safe Extra Low Voltage).
– The maximum output current is limited by the output with the
lowest current limitation, if several outputs are connected in
series.

Output Regulation of Double-Output Models
Output 1 is under normal conditions regulated to Vo nom,
independent of the output currents.
Vo2 depends upon the load distribution. If both outputs are
loaded with more than 10 % of Io nom, the deviation of Vo2
remains within ±5% of Vo1. The following 3 figures show the
regulation with varying load distribution.
T wo output s of a double-output model connected in parallel
behave like the output of a single-output model.
Note: If output 2 is not used, we recommend connecting it in
parallel with output 1. This ensures good regulation and
efficiency.

Inhibit for Remote On/Off
The outputs may be enabled or disabled by means of a
logic signal (TTL, CMOS, etc.) applied between the inhibit
input i (pin 18) and pin 14 (S– or Vo1–). In systems with
several converters, this feature can be used to control the
activation sequence of the converters. If the inhibit function
is not required, connect the inhibit pin 18 to pin 14.
Note: If pin 18 is not connected, the output is disabled.

Programmable Output Voltage (R-Function)
As a standard feature, the converters offer an adjustable
output voltage, identified by letter R in the type
designation. The control input R (pin 16) accepts either a
control voltage Vext or a resistor Rext to adjust the desired
output voltage. When input R is not connected, the output
voltage is set to Vo nom.
a)Adjustment by means of an external control voltage Vext
between pin 16 (R) and pin 14:
The control voltage range is 0 – 2.75 VDC and allows an
output voltage adjustment in the range of approximately
0 – 110% Vo nom.
Vo
Vext ≈ –––––– • 2.5 V
Vo nom
b) Adjustment by means of an external resistor:
Depending upon the value of the required output voltage
the resistor shall be connected
either: Between pin 16 and pin 14 (Vo < Vo nom) to
achieve an output voltage adjustment range of approxi-
mately 0 – 100% Vo nom.
or: Between pin 16 and pin 12 (Vo > Vo nom) to achieve an
output voltage adjustment range of 100 – 110% Vo nom.
Warning:
–Vext shall never exceed 2.75 V.
– The value of R'ext shall never be less than the lowest
value as indicated in table R'ext (for V0 > V0 nom) to
prevent the converter from damage!
Sense Lines (Single-Output Models)
Important: Sense lines must always be connected!
Incorrectly connected sense lines may activate the
overvoltage protection resulting in a permanent short-circuit
of the output.
This feature allows for compensation of voltage drops
across the connector contact s and if necessary, across the
load lines. We recommend connecting the sense lines
directly at the female connector.
To ensure correct operation, both sense lines (S+, S–)
should be connected to their respective power outputs
(Vo+ and Vo–), and the voltage difference between any
sense line and its respective power output (as measured
on the connector) should not exceed the following values:
Table 9: Maximum voltage compensation allowed using
sense lines
Output Total voltage difference Voltage difference
voltage between sense lines and between
their respective outputs Vo– and S–
5.1 V <0.5 V <0.25 V
12 V, 15 V, 24 V <1.0 V <0.25 V
Note: If the output voltages are increased above Vo nom via
R-input control, option P setting, remote sensing or option T,
the output currents must be reduced accordingly, so that
Po nom is not exceeded.

Notes:
– The R-Function excludes option P (output voltage
adjustment by potentiometer).
If the output voltages are increased above Vo nom via R-input
control, option P setting, remote sensing, or option T, the
output currents should be reduced, so that Po nom is not
exceeded.
– With double-output models the second output follows the
value of the controlled main output.
– In case of parallel connection the output voltages should be
individually set within a tolerance of 1 – 2%.

Battery Charging /Temperature Sensor
All converters with an R-input are suitable for battery
charger applications, but we recommend to choose the
models especially designed for this application, see Model
Selection, table 2.
For optimal battery charging and life expectancy of the
battery an external temperature sensor can be connected
to the R-input. The sensor is mounted as close as possible
to the battery and adjusts the output voltage according to
the battery temperature.
Depending upon cell voltage and the temperature
coefficient of the battery, different sensor types are
available, see Accessories.

Installation Instructions
Note: These converters have a power factor correction
(PFC). The LK4000/5000 models are intended to replace the
LK1000 and LK2000 converters in order to comply with IEC/
EN 61000-3-2. LK1000 is replaced by LK4003 with option K.
Switch off the system and check for hazardous voltages
before altering any connection!
These converters are components, intended exclusively
for inclusion within other equipment by an industrial
assembly operation or by professional installers.
Installation must strictly follow the national safety
regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings, and segre-
gation requirements of the end-use application.
Connection to the system shall be made via the matching
H15 female connector H15; see Accessories. Other
installation methods may not meet the safety
requirements.
Pin no. 24 ( ) is reliably connected with the case. For
safety reasons it is essential to connect this pin reliably to
protective earth. See Safety of Operator-Accessible Output
Circuits.
The phase input 30/32 (L~) is connected via a built-in fuse
(see Input Fuse and table 4), which is designed to protect
in the case of a converter failure.

BCD20001-G Rev AC, 16-Dec-2010 Page 21 of 29 www.power-one.com
K Series with PFC Data Sheet
150 – 280 Watt AC-DC Converters
An additional external fuse, suitable for the application,
might be necessary in the wiring to the other line input 26/
28 (N~) if:
• Local requirements demand an individual fuse in each
source line
• Phase and neutral of the mains are not defined or
cannot be assigned to the corresponding terminals (L~
to phase and N~ to neutral).
• Neutral and earth impedance is high or undefined
Notes:
– If the inhibit function is not used, pin no. 18 (i) should be
connected to pin no. 14 (S–/Vo1–) to enable the output(s).
– Do not open the converters, or warranty will be invalidated.
– Due to high current values, the converters provide two
internally parallel contacts for certain paths (pins 4/6, 8/10,
26/28 and 30/32). It is recommended to use both female
contacts in parallel connection order to keep the voltage
drop and the temperature of the contacts low.
– If the second output of double-output models is not used,
connect it in parallel with the main output.
Make sure that there is sufficient airflow available for
convection cooling. This should be verified by measuring
the case temperature, when the converter is installed and
operated in the end-use application; see Thermal
Considerations.
Ensure that a converter failure (e.g., an internal short-
circuit) does not result in a hazardous condition; see also
Safety of Operator-Accessible Output Circuits.
Standards and Approvals
The converters are safety-approved to EN/IEC
60950-1, and UL/CSA 60950-1 2nd Ed. (version
106 or greater).
The converters correspond to Class I equip-
ment and have been evaluated for:
• Building-in
• Basic insulation between input and case based on 250
VAC, and double or reinforced insulation between input
and output(s).
• Functional insulation between outputs.

• Overvoltage category II
• Pollution degree 2 environment
• Max. altitude: 2000 m.
• The converters fulfill the requirements of a fire enclosure.
All boards of the converters are coated with a protective
lacquer.
The converters are subject to manufacturing surveillance
in accordance with the above mentioned UL standards
and ISO 9001:2000. A CB-scheme is available.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power
supplies are not hermetically sealed.
Protection Degree
Condition: Female connector fitted to the converter.
• IP 30: All models except those with option P, and except
those with option D or V including a potentiometer.
• IP 20: All models fitted with option P, or with option D or
V with potentiometer.
Leakage Currents
Leakage currents flow due to internal leakage capacitances
and Y-capacitors. The current values are proportional to the
supply voltage and are specified in the table below.
Isolation
The electric strength test is performed in the factory as
routine test in accordance with EN 50116 and IEC/EN
60950 and should not be repeated in the field. Power-One
will not honor any warranty claims resulting from electric
strength field tests.

Safety of Operator-Accessible Output Circuits
If the output circuit of a converter is operator-accessible, it
shall be an SELV circuit according to IEC/EN 60950.
The table below shows a possible installation
configuration, compliance with which causes the output
circuit of a K Series AC-DC converter to be a SELV circuit
according to IEC/EN 60950 up to a configured output voltage
of 36 V (sum of nominal voltages connected in series) .
However, it is the sole responsibility of the installer to
ensure compliance with the applicable safety regulations.

P Potentiometer
A potentiometer provides an output voltage adjustment
range of +10/–60% of Vo nom. It is accessible through a hole
in the front cover. Option P is not available for battery
charger models and is not recommended for converters
connected in parallel.
Option P excludes the R-function. With double-output
models, both outputs are influenced by the potentiometer
setting (doubling the voltage, if the outputs are in series).
If the output voltages are increased above Vo nom via R input
control, option P setting, remote sensing, or option T, the
output current(s) should be reduced accordingly, so that
Po nom is not exceeded.
T Current Sharing
This option ensures that the
output currents are approx-
imately shared between all
parallel-connected convert-
ers, hence increasing sys-
tem reliability. To use this
facility, simply interconnect

and make sure that the

D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit
operates independently of the built-in input undervoltage
lockout circuit. A logic "low" (self conducting JFET) or "high"
signal (NPN output) is generated at the D output (pin 20),
when one of the monitored voltages drops below the
preselected threshold level Vt. This signal is referenced to
S–/Vo1–. The D output recovers, when the monitored
voltages exceed Vt + Vh. The threshold level Vbi is adjusted
in the factory. The threshold level Vto is either adjusted by a
potentiometer accessible through a hole in the front cover,
or adjusted in the factory to a fixed value specified by the
customer.
Option D exists in various versions D0 – DD, as shown in
the table below.
JFET output (D0 – D4):
Pin D is internally connected via the drain-source path of a
JFET (self-conducting type) to the negative potential of
output 1. VD ≤ 0.4 V (logic low) corresponds to a monitored
voltage level (Vi and/or Vo1) <Vt. The current ID through the
JFET should not exceed 2.5 mA. The JFET is protected by
a 0.5 W Zener diode of 8.2 V against external overvoltages.

of a NPN transistor to the negative potential of output 1. VD
< 0.4 V (logic low) corresponds to a monitored voltage
level (Vi and/or Vo1) > Vt + Vh. The current ID through the
open collector should not exceed 20 mA. The NPN output
is not protected against external overvoltages. VD should
not exceed 40 V.

1VME request: minimum 4 ms
2tlow min = 40 – 200 ms, typ 80 ms
3VV level not defined at Vo < 2.0 V
4The V signal drops simultaneously with the output
voltage, if the pull-up resistor RP is connected to Vo+;
the V signal remains high if RP is connected to an
external source.
V ACFAIL Signal (VME)
Available only for models with Vo = 5.1 V.
This option defines an undervoltage monitoring circuit for
the input and main output voltage. It generates the ACFAIL
signal (V signal) according to the VME standard.
The low state level of the ACFAIL signal is specified at a
sink current of IV ≤ 48 mA to VV ≤ 0.6 V (open-collector
output of an NPN transistor). The pull-up resistor feeding
the open-collector output should be placed on the VME
backplane.

Output configuration of options V2 and V3
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time th of at least 4 ms before the 5.1 V
output drops at full load to 4.875 V. This hold-up time th is
provided by the capacitance supporting the boost voltage
Vb. See Hold-up Time.

1Option V monitors Vb generated by the boost regulator. The
trigger level is adjusted in the factory to 355 VDC.
2Fixed value between 95% and 98.5% of Vo1
Option V operates independently of the built-in input
undervoltage lockout circuit. A logic "low" signal is
generated at pin 20, as soon as one of the monitored
voltages drops below the preselected threshold level Vt.
The return for this signal is S– or Vo1–. The V output
recovers, when the monitored voltage(s) exceed(s) Vt + Vh.
The threshold level Vto is adjusted in the factory to a
customer-specified value.
V-output (V2, V3):
Connector pin V is internally connected to the open collec-
tor of an NPN transistor. The emitter is connected to S– or
Vo1–. VV ≤ 0.6 V (logic low) corresponds to a monitored
voltage level (Vi and / or Vo) <Vt. The current IV through the
open collector should not exceed 50 mA. The NPN output
is not protected against external overvoltages. VV should
not exceed 60 V.

K Connector H15S4
Models with 5.1 V output are fitted with a connector H15S4
(rather than H15S2). This option should be used for new
designs and provides compatibility to LK1001 models.
B, B1, B2 Cooling Plate
Where a cooling surface is available, we recommend the
use of a cooling plate instead of the standard heat sink.
The mounting system should ensure sufficient cooling
capacity to guarantee that the maximum case tempera-
ture TC max is not exceeded. The cooling capacity is calcu-
lated by:
(100 % –
η)
PLoss = –––––––––– • Vo • Io

Efficiency η see Model Selection
For the dimensions of the cooling plates, see Mechnical
Data. Option B2 is for customer-specific models with
elongated case (for 220 mm DIN-rack depth).
G RoHS
Models with G as last character of the type designation are
RoHS-compliant for all six substances.
