Programming OVP with an External Voltage Source
CAUTION!
Always remove J3 mating connector from supply before soldering.
Programming OVP with a 0–5 VDC or 0–10 VDC Source
1. Set S1-3, the rear panel DIP Switch, UP, in the open position for 0–5 VDC programming
range.
2. Set S1-3, the rear panel DIP Switch, DOWN, in the closed position for 0–10 VDC
programming range.
3. Connect the external programming source between pins 3 (OVP programming
input/positive) and 12 (return). Varying the programming voltage from zero to maximum
will cause the OVP setting to vary from approximately 0 to 110% of the model rating.
4. Turn the power supply ON and adjust the external voltage programming to zero.
5. Set the front panel LOCAL/REMOTE switch to the REMOTE position and adjust the
external OVP programming source voltage. By pressing the OVP PREVIEW button and
looking at the front panel voltmeter setting, the external control can be adjusted to the
desired value.
6. Slowly increase the external output voltage programming signal until the red OVP LED
lights and the power supply shuts down.
S1 Switch Settings
S1-3 OPEN = 0–5V
S1-3 CLOSED = 0–10V
