F.4. Output Voltage Adjustment
The PEM1200 series has an OADJ pin, which allows the output voltage to be increased or decreased from its nominal value using a 1/16W power rating or
greater and 1% tolerance resistor connected between the OADJ pin and either the +VDC or –VDC pin as per figures below. Only one connection i.e. between
OADJ and +VDC or between OADJ and –VDC is permitted at a time. A change of more than ± 10% from nominal is not permitted. Please

-VDC. The ground return for the +VDC output. Max. current 3A per
pin.
+VDC. This pin provides the regulated output from the DC/DC
converter. Max. current 3A per pin.
OADJ. The output voltage can be adjusted from is nominal value,
by connecting an external resistor from this pin to either the +VDC
pin or the -VDC pin. For more details please see section F.4.
