Isolated remote output 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 enable the output, i.e.,
Zin ~ 6 kΩ turn on the output of the supply. This input control is
optically isolated from the power supply circuit up to 500
VDC. Circuit return Pin 2 (ISO RTN).
See Section 3.7.
Isolated circuit return used with isolated on/off control
—
J1-1 and J1-14.
Remote overvoltage set. A remote signal sets the over-
voltage trip level. 0.25-5.5 VDC = 5-110%. Apply a 10.5
Zin ~
VDC to 13.3 VDC signal for 7 seconds to reset an OVP

condition. Circuit return Pin 6 (COM).
See Section 3.8.
