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 PROTECTIONS parameter conditions/description input under voltage protection Power supply shuts down when ac input is under 80 ±5 Vac.
