(1)The power supply unit will have no output if the shorting connector (accessory comes along with the PSU) is not assembled. It contains
(2)Factory setting is shorted as Fig1.1
three shorting wires : one is from ON/OFF (pin13) to 12V-AUX (pin14), two is from PV(pin5) to PS (pin6) and the other is from PC (pin7) to PO (pin8).

ON/OFF
Auxiliary voltage output, 10.8~13.2V, referenced to pin 12(G-AUX). The maximum load current is 0.1A. This output is not controlled by the
"remote ON/OFF control".
Open collector signal, referenced to pin10,11(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum
external voltage is 5.6V.
These pins connect to the negative terminal (-V). Return for DC_OK Signal output.
Turns the output on and off by electrical or dry contact between pin 13 ( ON/OFF) and pin 14 (12V-AUX). Short: Power ON, Open: Power OFF.
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.
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
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V).

PV
Connect to external DC voltage source for output voltage triming, referenced to pin 10,11 (GND). Output voltage can be trimmed between
40 ~ 110% of the rated output voltage.

PC
Short connecting between PV (pin5) and PS (pin6) if "output voltage TRIM" function is not used.
Short connecting between PC (pin7) and PO (pin8) if output current trim function is not used.
Connect to external DC voltage source for output current triming, referenced output current can be trimmed between 40 ~ 110% of the rated
output current. Please refer to function manual for details.
