6 Maximum Line Regulation
Maximum line regulation is the maximum output voltage
change when the input voltage is slowly varied within the
input voltage range. The measurement point for the input
and output voltages are ±Vin, ±Vo1 and ±Vo2 respec-
tively.
7 Maximum load regulation
Maximum load regulation is the maximum output voltage
value change when varying the load current slowly within
the standard output current range. The measurement point
for the input and output voltages are ±Vin, ±Vo1 and ±
Vo2 respectively.
8 Brownout
There will be output voltage overshoot during brown-out
(momentary input line off) condition.
9 Over Current Protection
The PAH75D24 SERIES is equipped with an over current
protection circuit. When the short or overload condition is
removed, the output will automatically recover. This set-
ting is fixed and cannot be varied externally. If the short or
overload condition continues, the power module could be
damaged due to the heat condition.
 Over Voltage Protection
There are 2 types of over voltage protection method avail-
able for PAH75D24 SERIES. In the standard model, a
latching shutdown method is adopted. For this method
there are two ways to reset the power module after OVP
protection triggers. They are by (i) giving a pulse to the
control pin or (ii) recycling the input voltage. In the /V op-
tional model, the power module will shutdown after OVP
protection triggers but will recover automatically when over
voltage is removed.
 Thermal Protection
The PAH75D24 SERIES have a thermal protection circuit
that senses the baseplate temperature between the range
of 105℃ to 130℃ for an over temperature condition.

Under a condition where the ambient temperature or the
power module internal temperature rises excessively, the
thermal protection circuit will shut down the power mod-
ule. The power module will recover automatically when the
baseplate temperature cools down.
 ON/OFF Control (CNT)
Without turning the input on and off, the output can be en-
abled and disabled using this function. This control circuit
is on the input side of the power module; CNT terminal
pin. There are two options available in this function, which
are Negative Logic and Positive Logic. In the standard
model where Negative Logic is used, power module will
turn on when the CNT terminal pin is shorted to –Vin or a
low logic voltage is provided. The Power module will turn
off when CNT terminal pin is open or Logic high is provid-
ed. In the /P optional model where Positive Logic is used,
the control method is vice versa to Negative logic.
The maximum CNT pin voltage when it is opened is 7V.
The maximum low logic sourcing current is 0.6mA. When
using this function, attach a 0.1uF capacitor between the
CNT and –Vin terminals as close as possible.
Remote ON/OFF control can also be exercised by opening
or closing the contacts of a switch or relay, or by operating
a transistor as a switch in series with the CNT terminal.
Standard remote ON/OFF control circuit is provided in
the primary circuit. For secondary control, isolation can be
achieved through use of an optocoupler or relay.
Below tables summarize the CNT levels and output states
with different logic types.
a） Negative Logic: (Standard model)
b） Positive Logic: (/P option)
 Operation Temperature
The baseplate temperature range for PAH75D24 SERIES
is from -40℃ to 100℃.
 Operation Humidity
Avoid the buildup of condensation on or in the power mod-
ule.
