Test conditions and notes10

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. The rated power includes 5Vsb @ 0.6A.
3. The rated power includes 5Vsb @ 0.8A.
4. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
5. Tolerance : includes set up tolerance, line regulation and load regulation.
6. Derating may be needed under low input voltages. Please check the derating curve for more details.
7. Touch current was measured from primary input to DC output.
8. 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).
9. HS1,HS2 & HS3 can not be shorted.
10. 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 )

FAQ

Can I use the RPSG-160-48 for a 48V industrial controller or PLC-related device?

This model is a constant voltage 48V power supply with up to 2.3A output. It is generally suited to 48V industrial or automation equipment that requires a regulated 48V supply and stays within the 113.4W power rating.

Is the RPSG-160-48 suitable for 48V embedded or medical electronic systems?

The unit provides a constant 48V output and is identified as a medical power supply. Buyers evaluating embedded or medical equipment should confirm the load stays within 2.3A and 113.4W and that the listed IEC 60601-1, ANSI/AAMI ES60601-1, and EAC approvals match the end application.

Can this 48V power supply be used in industrial monitoring or communication equipment?

It can fit 48V industrial monitoring or communication hardware that needs a constant voltage source rather than a current-regulated supply. The available output is 48V at 2.3A, with a total power limit of 113.4W.

Is the RPSG-160-48 intended for indoor or outdoor use?

The listed operating temperature is -20°C to +70°C, so the temperature range is broad for indoor equipment environments. No IP rating is provided in the specs, so the product page does not establish outdoor or washdown suitability from enclosure protection data.

How does the RPSG-160-48 compare with the other RPSG-160 models?

Within the RPSG-160 family, the listed siblings are 5V 20A at 103W, 12V 9.1A at 112.2W, 15V 7.3A at 112.5W, 24V 4.6A at 113.4W, and this 48V 2.3A version at 113.4W. All are shown in the same series, while the output voltage, output current, and wattage vary by model.
