ISO
ON/OFF
Zin ~ 6 k
Ω
Isolated remote on/off. Externally supplied AC/DC voltage source
for on/off control. A positive (+) 12 to 240 VAC or 6 to 120 VDC
voltage will turn on the supply. This input control is optically isolated
from the power supply circuit up to 500 VDC. See Section 3.5.
2 ISO RTN —
Isolated circuit return used with isolated on/off control
J1-1 and J1-14.

REM OC
SET
Zin ~
20 k
Ω
Remote overcurrent set. A remote signal sets the overcurrent
trip level. 0-5.5 VDC = 0-110%. Apply a 10.5 VDC to 13.3
VDC signal for 4 seconds to reset an OCP condition. See
Section 3.6.
