NOTE
- All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25’C of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0. 1uf & 47uf parallel capacitor.
- Tolerance : indudes set up tolerance, line regulation and load reguiation
- Derating may be needed under low input voltages. Please check the derating curve for more details.
- Length of set up time is measured at first cold start. Tuming ON/OFF the power supply may lead to increase of the set up time.
- No load power consumption<0.5W when RC- & RG+ (CN100 pin1,2) 0 ~ 0.8V or short
- When the input voltage is less than 40VAG, the SPS may exhibit degradation of performance. The final product manufacturers must re-confirm this deviation that does not affect basic safety or essential performance.
- The power supply is considered a componert which wil be installed into a final equipment. All the EMG tests are been exectted by mounting the unit on 2 360mm”360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that stil meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supples.”(as available on https://www.meanwel.com/Upload/PDF/EMI_statemert_en.pdf)
- The ambient temperature derating of 3.5’C/1000m with faniess models and of 5’C/1000m with fan models for operating alttude higher than 2000m(500t)

Output Derating VS Input Voltage 
Function Description of CN100
| Pin No. | Function | Description |
| 1 | RC+ | Turns the output on and off by electrical or dry contact between pin 2 (RC-), Short: Power OFF, Open: Power ON. |
| 2 | RC- | Remote control ground. |
| 3 | AUX | Auxiliary voltage output, 4.75~5.25V, referenced to pin 4(AUXG). The maximum load current is 0.3A. This output is not controlled by the “remote ON/OFF control”. |
| 4 | AUXG | Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V). |
| 5 | DC-OK | DC-OK Signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on. |
| 6 | GND | This pin connects to the negative terminal(-V). Return for DC-OK signal output. |
| 7 | +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. |
| 8 | -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. |
Function Manual
1.Remote Sense
The remote sensing compensates voltage drop on the load wiring up t0 0.5V.
2.DC-OK Signal
DC-OKsignal is a TTL level signal. High when PSU turns on.
| Between DC-OK(pin5) and GND(pin6) | Output Status |
| 3.3 ~ 5.6V | ON |
| 0 ~ 1V | OFF |
3.Remote Control
The PSU can be turned ON/OFF by using the “Remote Control” function.
| Between RC+(pin1) and RC-(pin2) | Output Status |
| SW ON (Short) | OFF |
| SW OFF (Open) | ON |
