PAH
1 External Components
The table below shows the recommended values for the
external components above.
＊ (1) The above value is for operating temperature range
1 Input Voltage Range
The operating input voltage range of PAH-S48 SERIES
is 36〜76VDC. The maximum allowable input ripple volt-
age (Vrpl) is 4V. Any ripple that exceeds this value might
cause the module to become unstable.
Protection for input reverse connection
Please connect protection diode and a fuse as shown
below.
2 Output Voltage Adjust Range
The output voltage of power module can be adjusted by
connecting an external resistor (R
and either the +S or –S pins. With an external resistor (R
between TRIM pin and –S pin, output voltage will decrease

PAH-S48 SERIES module is not internally fused. To en-
sure safe operation and to receive each safety standard
approval, please connect an external fuse, F1 as shown in
the diagram above.
Input capacitor C1 is recommended to stabilize the mod-
ule when the module is powered from a high impedance
source.
Capacitor C2 is used to absorb noise coming from the
module itself. This capacitor will also help the EMI perfor-
mance of the module.
The function of capacitor C3 is to reduce the output ripple
of the power module whereas the capacitor C4 is to reduce
high frequency noise that is produced by the module.
If in any application where an input reversal connection is
possible, a protective diode that is connected across +Vin
and –Vin is recommended.

nal resistor (R
