USP-500 series - Advice

500W Single Output with PFC FunctionUSP-500 seriesFunction Description of CN50Pin No. Function DescriptionCS1Current sharing signal. When units are connected in parallel, the CS pins of the units should be connected to allow current balance(Optional) between units.2,83456-SRC-RC-RC+GNDDC-OK7 +SNegative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be twisted in pair tominimize noise pick-up effect. The maximum line drop compensation is 0.5V.Return for RC+ signal input.Turns the output on and off by electrical or dry contact between pin 4 ( RC+) and pin 3 (RC-). 0~0.8V: Power ON, 4~10V: Power OFF.This pin connects to the negative terminal (-V). Return for DC_OK signal output.DC-OK signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on.Positive sensing. The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be twisted in pair tominimize noise pick-up effect. The maximum line drop compensation is 0.5V.Function Manual1.Remote ControlThe PSU can be turned ON/OFF by using the"Remote Control" function.Between RC+(pin4) and RC-(pin3)SW OFF (0 ~ 0.8V)SW ON (4 ~ 10V)Output StatusONOFFCN501278+VTB2-VLED+LOAD-1NCCN50GND-S RC+ DC-OK7+S-S2SW8Fig 1.1External PowerSourceI=6~20mA2.DC-OK SignalDC-OK signal is a TTL level signal.
