PAH75D48 SERIES module is not internally fused. To
ensure 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 per-
formance of the module.
The function of capacitor C3 is to reduce the output ripple
of the power module and high frequency noise that is pro-
duced by the module.
If in any application that an input reversal connection is
possible, a protective diode which is connected across
+Vin and -Vin is recommended.
3 Input Voltage Range
The operating input voltage range of PAH75D48 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.
4 Output Voltage Adjust Range
The output voltage of power module can be adjusted by
connecting an external resistor (R
pin and either the +Vo or –Vo pins. There are two options
available for the trim function for models 5033 & 3325,
which are standard & /Z option.
With an external resistor (R
pin, output voltage will decrease as shown in diagram be-
low.
If the external resistor (R
TRIM pin and –Vo pin, the output voltage will increase.
Diagram shown below is the output voltage trim up con-
nection.

The equations and graphs for the required external resistor
(R
of ΔVo% is as shown in the next page.
For output adjust down, the allowable output current have
to be the same as nominal output current.
For output adjust up, the allowable output current have to
derate to maximun power.
