3.12 Remote Overvoltage 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 reset,
see note below).
Remote Overvoltage Protection (OVP) programming is summed with the front
panel or remote digital setting; see Section 3.9. A remote DC voltage source
can be connected externally between Pins J1-3 (REM OV SET) and J1-6
(COM) to set the output overvoltage trip level. A 0.25-5.5 VDC signal equals
5-110% of rated output voltage. See Figure 3-18 for connection requirements.
Note:
To reset an OVP, apply a 10.5–13.3 VDC signal to Pin J1-3 for a
minimum of 7 s.
