3.6 REMOTE OVERCURRENT SETPOINT
CAUTION!
Do not program the remote overcurrent set point greater than 10% (5.5V) above
the power supply rated current (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 OC SET) to set the output overcurrent trip level. A 0-
5.5 VDC signal equals 0-110% of rated output voltage. See Figure 3–11 for
connection requirements.

NOTE: The Remote OCP trip level will ALWAYS take precedence over the
local trip level, even if the local OCP trip level is set to a lower value. To reset
an OCP externally, apply a 10.5–13.3 VDC signal to J1-3 for a minimum of four
(4) seconds.
