REMOTE OVERVOLTAGE SETPOINT

3.8
CAUTION!
Do not program the remote overvoltage set point greater than 10% (5.5V)
above the power supply rated voltage (except as noted) as internal power
supply damage may occur.
A remote DC voltage source can be connected externally between
terminals J1-6 (COM) and J1-3 (REM OV SET) 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: The Remote OVP trip level will ALWAYS take precedence over the
local trip level, even if the local OVP trip level is set to a lower value. To
reset an OVP externally, apply a 10.5–13.3 VDC signal to J1-3 for a
minimum of four (4) seconds.
