remote sense1
Designated as RS+ and RS- on CN3. Total voltage compensation for cable losses with respect to the
main output.
remote on/off
Defined RSW on CN3, requiring a low signal to inhibit output.
LED display (LED 1)
Green - the power supply is operating normally.
Orange - when any protection occurs or RSW is low.
power good
Designated as PG on CN3. This signal goes high 100~500 ms after the output reaches regulation. It
goes low at least 1 ms before loss of regulation.
current sharing
Designated as CSH on CN3, optional single wired for forced surrent sharing function and parallel up to
4 units within 10% accuracy at full load.
current monitor
Designated as CMN on CN3 for for current sense for 0.5~3 Vdc to represent 0~100% output current.
AC fail (optional)
Designated as ACF on CN3 to monitor the input voltage when input goes under 80 ±5 Vac the signal
will go low (0 V) and then go high (+5 V) once it reappears over 86 Vac.
Notes:
1. Not available for current sharing models

Power supply shuts down when ac input is under 80 ±5 Vac. When ac line reappears over 86 ±5 Vac,
the power supply restarts automatically.
