NOTE
1. All parameters NOT specially mentioned are measured at 48, 96VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.

Function Description of CN3
SD-500
series
Pin No. Function Description 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 to 1 +S minimize noise pick-up effect. The maximum line drop compensation is 0.5V. 2 3 4 5 6 -S Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be twisted in pair to minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
Open collector signal, reference to pin4(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum O/P OK external voltage is 13V. GND RC RCG These pins connect to the negative terminal (-V). Remote ON/OFF Remote ON/OFF ground

2.Output OK signal "Output OK" is an open collector signal. It indicates the output status of the PSU. It can operate in two ways : One is sinking current from external signal ; the other is sending out a voltage signal. 2-1 Sink current : The maximum sink current is 10mA and the maximum external voltage is 13V. 2-2 Voltage signal :
Between O/P OK(pin3) and GND(pin4) 0 ~ 0.5V 12 ~ 13V Output Status ON OFF
