Engineering Data
De-rating
Output De-rati ng VS. Input Voltage
Note
1. Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
2. If the output capacity is not reduced when the
surrounding air temperature >55
°C, the
device will run into Over Temperature
Protection. When activated, the output
voltage will go into bouncing mode and will
recover when the surrounding air
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
3.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 20mm with adjacent units
while the device is in operation.
4.
Depending on the surrounding air
temperature and output load delivered by the
power supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please do not hesitate to contact
info@deltapsu.com f or more detai ls.

Safety Instructions
– If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further
information.
– The device is not recommended to be placed on low thermal conductive surface. For exampl e, plastics.
– The enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do not
touch the device while it is in operation or immediately after power is turned OFF. Risk of burning !
– Do not touch the terminals while power is being supplied. Risk of electric shock.
– Prevent any foreign metal, particles or conductors from entering the device through the openings during installation.
It may cause electric shock, safety hazard, fire and/or product failure.
– Warning: When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device,
remove L and N connections before removing the Earth connection. The power supply must be mounted by metal screws onto a
grounded metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded metal
surface.

Functional Manual
Remote ON/OFF Function You can remotely control the power supply unit
to turn ON/OFF by using an external DC source.
Follow the DC power source voltage and current
limiting defined in the table below.
Built-in Resistor Ri (ohm) Voltage Between RC+ and RC- (V) Input Current (mA)
Output ON Output OFF
820 5-12.5 0-0.5 20 Max
Notes
1. Remote ON/OFF circuits are isolated from input, output and PE.
2. Please check if the polarity of the wire connector is the same as the external DC source. If not, the power would not turn on and
the internal components may be damaged.
3. You do not need an external resistance RO for current limit while the output voltage of external DC source is within the range of
5-12.5V. If the output voltage exceeds 12.5V, please use the following equation for the value of current limit resistance RO.

Functions
Start-up Time
The time required for the output voltage to reach 90% of its set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its set value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 95% of its set value, after the input voltage is removed.
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak
value decreases exponentially during subsequent cycles of AC
voltage.
Dynamic Response
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 0 to
100% of its rated current.

Overload & Overc ur rent Protections
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds
105-135% of IO (Max load). In such occurrence, the VO will start
to droop and once the power supply has reached its maximum
power limit, the protection is activated and the power supply will
go into “Hiccup mode” (Auto-Recovery). The power supply will
recover once the fault condition of the OLP and OCP is removed
and IO is back within the speci f icat ion s.
It is not recommended to prolong the duration of IO when it is
<105% but >100%, since it may cause damage to the PSU.
Short Circuit Protection
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied,
the output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power
supply will return to normal operation after the short circuit is
removed.
Overvolt age Prot ec tio n
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 3 under “Protections”.
The power supply should be latch.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). In the event of a higher operating
temperature at 100% load, the power supply will run into OTP
when the operating temperature is beyond what is recommended
in the de-rating graph. When activated, the output voltage will go
into bouncing mode until the temperature drops to its normal
operating tem perat ur e as reco mmended in the de-rating gra ph.

Delta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and ele ctr on ic equ ip ment”.
This product conforms to this standard.
PFC – Norm EN 61000-3-2
Line Current Harmonic content
Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying
to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial
aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard,
therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
