REMOTE OVERVOLTAGE PROTECTION
PROGRAMMING

CAUTION!

Do not program the remote overvoltage setpoint greater than 10%
above the power supply rated voltage (5.5 VDC programming voltage
source), as internal power supply damage might occur (except as noted
for reset).


A remote DC voltage source can be connected externally between Pins J1-3
(REM OV SET) and J1-6 (COM) to set the Overvoltage Protection (OVP) trip
level. A 0.25-5.5 VDC signal equals 5-110% of rated output voltage. See
Figure 3-17 for connection requirements. The Remote OVP setpoint will
always take precedence over the front panel (local) trip level, even if the front
panel (local) OVP trip level is set to a lower value.

Note:

To reset an OVP, apply a 10.5

–13.3 VDC signal to Pin J1-3 for a

minimum of 7 s.
