!"#Function
2.1 CNT
! The products provide a control function allowing the user to turn the output on
and off using an external circuit.
! When CNT disconnects or connects with +Vin or is in the midair, output is on.
When CNT connects with –Vin directly, output is off.
! For 48Vin products, applying a voltage greater than 18V to the CNT pin will
enable the output, while applying a voltage less than 4.5V will disable it. For
24Vin products, ap plying a voltage greater than 24V (it is unlimited wh en the
CNT connects with +Vin directly.) will enable the output, while applying a
voltage less than 4.5V will disable it. Grounding of CNT is –Vin.
!
! During operation, the working current of CNT is related to its input voltage.

! ON/OFF control can be realized through mechanical switcher or transistor
! In the isolated appliction, CNT control can be realized through optoisolator or
relay.
! It is recommended to parallel a 0.1 F capacitor to remove the interference
when the control line is too long.
! When not use CNT function, connect CNT with +Vin.

2.2 input over/under voltage shutdown
! The module has input over/under voltage protection.
! When the input power is below 65%~75% rated input voltage, the input
under-voltage protection active, output is cut off. There is a 1-2V hysteresis
between the under-voltage shutdown point and restart up point.
! When the input power is up than 150%~159% rated input voltage, the input
over-voltage protection active, output is cut off. There is a 1-3V hysteresis
between the over-voltage shutdown point and restart up point.

2.3 Output over-current protection
! AEW series DC/DC converters feature Over-current Protection (OCP) circuits.
When output current exceeds 110% to 150% of rated current, such as during a short
circuit condition, the output will shutdown immediately, and can tolerate short
circuit conditions indefinitely.
! When the overcurrent condition is removed, the converter will automatically
restart.
2.4 Output over-voltage shutdown (OVP)
! The AEW series provides over-voltage protection on the output, which will
shut the output off if the voltage exceeds 116 to 150% of the nominal output
voltage, and the output is shutdown.#
! It must power the module on again to recover the output.#
! If the module is trimmed up to the voltage, which exceeds the 110% rated
output voltage, the output over-voltage protection will be probably triggered
off.#
! For dual output products:
Through testing the over-voltage condition between +Vo and –V, the
over-voltage protection active (operating at 116% 150% rated output
voltage).
! For triple output products:
Through testing the over-voltage condition between +Vo and COM, the
over-voltage protection active. When Vo1 exceeds 116%~150% rated output
voltage, the over-voltage protection active. After the protection, please turn off
the power supply, and restart after 2-3 seconds, the output will be normal.

2.5 Trim function
! Output voltage trim range is ±10%. Trimming up by more than 10% of the
nominal output may activate the OVP circuit or damage the converter. Trimming
down more than 10% can cause improper regulation.
! The output voltage of the AEW series can be trimmed using the trim pin
provided. Applying a voltage to the trim pin through a voltage divider or resistance
from the output will cause the output to increase or decrease by up to 10%.
! When trimming a dual output converter, both outputs trim simultaneously.
! Trim down and trim up circuits and the corresponding configuration are shown
in the following figures.

3. Input and O utput
3.1 Input fuse
The AEW power module has no internal fuse. An external fuse must always
be employed! To meet international safety requirements, a 250 Volt rated fuse
should be used. If one of the input lines is connected to chassis ground, then
the fuse must be placed in the other input line.
Standard safety agency regulations require input fusing. Recommended fuse
ratings for the AEH Series are shown in the following table:#
Input voltage Dual output Triple output

3.2 Input filtering
! Input filters are included in the converters to help achieve standard system
emissions certifications. Some users however, may find that additional input
filtering is necessary. The AEW series has an internal switching frequency of
280 kHz so a high frequency capacitor mounted close to the input terminals
produces the best results. To reduce reflected noise, a capacitor can be added
across the input as shown in following figure, forming a π filter.
For conditions where EMI is a concern, a different input filter can be used.
Following figure shows an input filter designed to reduce EMI effects.

4. Decoupling
Noise on the power distribution system is not always created by the converter.
High-speed analog or digital loads with dynamic power demands can cause
noise to cross the power inductor back onto the input lines. Noise can be
reduced by decoupling the load. In most cases, connecting a 10 µF tantalum
capacitor in parallel with a 0.1µF ceramic capacitor across the load will
decouple it. The capacitors should be connected as close to the load as
possible.
5. Powe r dissipation
! Parallel Power Distribution
Following figure shows a typical parallel power distribution design. Such
designs, sometimes called daisy chains, can be used for very low output
currents, but are not normally recommended. The voltage across loads far
from the source can vary greatly depending on the IR drops along the leads
and changes in the loads closer to the source. Dynamic load conditions
increase the potential problems.
! Radial Power Distribution
Radial power distribution is the preferred method of providing power to the
load. Figure 19 shows how individual loads are connected directly to the
power source. This arrangement requires additional power leads, but it avoids
the voltage variation problems associated with the parallel power distribution
technique.

! Mixed Distribution
In the real world a combination of parallel and radial power distribution is
often used. Dynamic and high current loads are connected using a radial
design, while static and low current loads can be connected in parallel. This
combined approach minimizes the drawbacks of a parallel design when a
purely radial design is not feasible.
! Redundant Operation
A common requirement in high reliability systems is to provide redundant power
supplies. The easiest way to do this is to place two converters in parallel, providing
fault tolerance but not load sharing. Oring diodes should be used to ensure that
failure of one converter would not cause failure of the second. Figure 21 shows
such an arrangement. Upon application of power, one of the converters will provide
a slightly higher output voltage and will support the full load demand. The second
converter will see a zero load condition and will idle. If the first converter should
fail, the second converter will support the full load. When designing redundant
converter circuits, Shottky diodes should be used to minimize the forward voltage
drop. The voltage drop across the Shottky diodes must also be considered when
determining load voltage requirements. \

6. Input Reverse Voltage Protection
Under installation and cabling conditions where reverse polarity across the input
may occur, reverse polarity protection is recommended. Protection can easily be
provided as shown in following. In both cases the diode used is rated for 2A/100V.
Placing the diode across the inputs rather than in-line with the input offers an
advantage in that the diode only conducts in a reverse polarity condition, which
increases circuit efficiency and thermal performance.
7. Series operating
When converters are connected in series to increase the output voltage, diodes
should be added as shown in following figure. Choose low forward voltage drop
diodes, such as shottky diodes. The reverse voltage of the diode should be greater
than the output voltage, and the diode’s turn-on current should be greater than the
series load current. The maximum operating output current of the series connection
should not be greater than the maximum output current of any single converter.

8. Installation
! Installation method
AEW series converters can be mounted in any orientation, but care should be taken
to allow for free airflow. Common placement techniques put heat sources such as
power components at the end of the airflow path or provide separate airflow paths.
This arrangement keeps other system equipment cooler and increases component
life spans.
