Output Trim (Single Output Models)
A simple external circuit may be used to adjust Vout on
single output models. To adjust the output DOWN, con-
nect 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 output pin and the Vout
trim pin. Resistor values are given in the chart below.
For UP/Down trimming capability, connect a 10 kW poten-
tiometer between the plus and minus outputs with the
wiper arm connected to the Vout trim pin.
Care should be taken that the maximum output power of
the unit does not exceed the maximum rating.
