1. All parameters NOT specially mentioned are measured at 230VAC 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
(as available on http://www.meanwell.com)
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. The power supply unit will have no output if the shorting connector is not assembled. It contains three shorting wires: one is from on/off(pin13) to
12V-AUX(pin14), two is from PC(pin7) to PO(pin8) and the other is from PV(pin5) to PS(pin6). Please refter to function manual for details.

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).

3.DC_OK signal
"DC_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 TTL
signal ; the other is sending out a TTL voltage signal.

The maximum sink current is 10mA and the maximum
external voltage is 5.6V.
