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. All the EMC tests are been executed by mounting the unit on a 720mm*360mm metal plate with 1mm of thickness. 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

5. Derating may be needed under low input voltages. Please check the derating curve for more details.

6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

Function Description of CN51

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.
2| -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.
3| O/P OK| Open collector signal, referenced to pin4(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum external voltage is 13V.
4| GND| These pins connect to the negative terminal (-V).
5| AUX| Auxiliary voltage output, 10.8~13.2V referenced to pin6(AUXG).The maximum load current is 0.25A.
6| AUXG| Auxiliary voltage output ground. The signal return is isolated from the output terminals(+V & -V).

8| RC2| Remote ON/OFF
9| RCG| Remote ON/OFF ground
10| NC| No connection

Function Manual

1. Remote ON/OFF
   (1)Remote ON/OFF control becomes available by applying voltage in CN51
   (2)Table 1.1 shows the specification of Remote ON/OFF function
   (3)Fig.1.2 shows the example to connect Remote ON/OFF control function

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)| Output Status
   ---|---
   0 ~ 0.5V| ON
   12 ~ 13V| OFF

3. Remote Sense
   The remote sensing compensates voltage drop on the load wiring up to 0.5V.
