| 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 0.1μF & 47μF 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 360mm*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. 7. 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). ※ Product Liability Disclaimer：For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx |

Function Description of CN3
| Pin No. | Function | Description |
| 1 | +S | 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. |
| 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, reference 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 | RC | Remote ON/OFF |
| 6 | RCG | Remote ON/OFF ground |
Function Manual
- Remote ON/OFF
(1)Remote ON/OFF control becomes available by applying voltage in CN3
(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

(B)Using external voltage source
- 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 signalthe 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 
- Remote Sense
The remote sensing compensates voltage drop on the load wiring up to 0.5V.
