Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Touch current was measured from primary input to DC output.
  5. 5. 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).
  6. 6. Heat Sink HS1,HS2,HS3 can not be shorted.
  7. 7. 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 RPS-75-48 for a 48V industrial controller or PLC-related device?

This model is intended for 48V DC equipment that needs a constant voltage supply and stays within 1.6A and 76.8W. It can fit industrial control, automation, or embedded hardware that is specified for 48V input within that load range.

Is this power supply suitable for 48V medical or laboratory equipment?

It can be used with 48V medical or lab equipment that requires constant voltage and draws no more than 1.6A or 76.8W. The unit is described as medical safety approved, which can matter for regulated equipment builds.

Can the RPS-75-48 power a small 48V embedded or telecom device?

Yes, if the device requires 48V DC and its total load does not exceed 1.6A or 76.8W. That makes it more appropriate for lower-power 48V electronics than for heavier 48V loads.

Is the RPS-75-48 appropriate for indoor or outdoor use?

The listed operating temperature is -20°C to +70°C, so the temperature range is broad for indoor equipment enclosures. No IP rating is listed, so it should be treated as a power supply for protected indoor installations rather than exposed wet or outdoor locations.

How does the RPS-75-48 compare with the other RPS-75 models?

Within the RPS-75 family, the available outputs are RPS-75-3.3 at 49.5W and 3.3V 15A, RPS-75-5 at 70W and 5V 14A, RPS-75-12 at 75.6W and 12V 6.3A, RPS-75-15 at 75W and 15V 5A, RPS-75-24 at 76.8W and 24V 3.2A, RPS-75-36 at 75.6W and 36V 2.1A, and RPS-75-48 at 76.8W and 48V 1.6A. The main difference is the output voltage and current rating for each model.
