Notes:
1. Measured with Output 1 at 55% of load while varying output 2 from 10% to 100% load.
2. When measuring output ripple, it’s recommended that an external 4.7 µF ceramic capacitor be
placed from the +Vout pin to the -Vout pin for single output units and from each output to common
for dual outputs units.
3. These converters are specified for operation without

Mechanical Dimensions
External Trim
A simple external circuit may be used to
adjust the converter output (single output
models only). To adjust the output DOWN,
connect a 5%, 3W resistor between the
plus output pin and the Vout trim pin. To
adjust the output UP, connect a 5%, 3W
resistor between the minus utput pin and
the Vout trim pin.
For UP/Down trimming capability, connect
a 10 kW potentiometer between the plus
and minus outputs with the wiper arm
connected to the Vout trim pin.
The trim range is
±10%.
