The equation shown below determines the required exter-
nal resistor (R
age change of Δ%.
Vo = Nominal output Voltage.
The graph shown is the external resistor (R
a percentage output voltage change of Δ% .
If the output voltage is raised above its nominal value, the
output current needs to be derated to a value such that the
output power does not exceed the maximum output power
specified in the specification sheet. In addition to that,
there is also a limitation to the input voltage range for the
5V version only which is as shown below.
3 Output Ripple & Noise Measurement Method
The method for output ripple and noise are based upon
JEITA RC-9002A. Upon measurement of the ripple volt-
age, make sure that the oscilloscope probe leads are not
too long.

4 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 voltage are ±Vin and ±S (sensing point) re-
spectively.
5 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 and ±S (sense
point) respectively.
6 Brownout
There will be output voltage overshoot during brown-out
(momentary input line off) condition.
7 Over Current Protection
The PAH-S48 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.
8 Over Voltage Protection
There are 2 types of over protection method available for
the PAH 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 optional model, the power
module will shutdown after OVP protection triggers but will
recover automatically when over voltage is removed.
9 Thermal Protection
The PAH-S48 SERIES have a thermal protection circuit
that sense 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 module. The
power module will recover automatically when the base-
plate temperature cools down.
 Remote Sensing
The PAH-S48 SERIES is equipped with remote sensing
terminals, which compensate for the voltage drops between
the power supply output terminals and the load terminals.
Remote sensing should be performed at the load. When
remote sensing is not required (local sensing), short the +S
with the +V terminal, and the -S with the -V terminal. The
