Output Voltage Adjustment
Mechanical Dimensions
www.micropowerdirect.com
A simple external circuit may be used to adjust the
converter output. The range of adjustment is ±10%.
To adjust the output down, connect a 5%, 3W resistor
from the plus sense pin (7) to the VOUT trim pin (6). To
adjust the output up, connect a 5%, 3W resistor from
the minus sense pin (5) to the VOUT trim pin. For up/
down trimming, connect a 10 k⍀ potentiometer from
the plus to the minus sense pins. Connect the wiper
arm to the VOUT trim pin.
For a table of trim resistor values, contact the factory.
