Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. Touch current was measured from primary input to DC output.
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).
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-200-48 for a 48V industrial control or automation system?

Yes, it is a constant-voltage 48V supply rated 3A and 144W with convection cooling, or 4.2A and 201.6W with a 10CFM fan, which fits automation equipment that requires a regulated 48V DC source within that load range. Its 80-264VAC input also supports use in facilities with a wide AC input range.

Is the RPS-200-48 suitable for 48V telecom or network equipment?

It can be a fit for 48V equipment that runs on constant voltage and stays within 3A/144W convection-cooled, or 4.2A/201.6W with a 10CFM fan. Buyers should match the equipment's required DC voltage and total load to the unit's 48V output rating.

Can this power supply be used in medical or lab equipment?

Yes, this model is described as medical safety approved and features extreme low leakage current, which makes it relevant for medical or laboratory devices that require 48V DC. The output is limited to 48V at 3A (144W) with convection cooling, or 4.2A (201.6W) with a 10CFM fan.

How does the RPS-200-48 compare with other RPS-200 models?

Within the RPS-200 range, the convection ratings are 140.4W at 11.7A for 12V, 141W at 9.4A for 15V, 141.6W at 5.9A for 24V, 143.1W at 5.3A for 27V, and 144W at 3A for 48V, rising to about 200W with a 10CFM fan. The RPS-200-48 and RPS-200-48-C share the same rated output, though the enclosed -C follows a more restrictive convection derating curve.

Can the RPS-200-48 be used in outdoor or harsh-temperature locations?

The operating temperature range is -30°C to +70°C, with derating at higher ambient temperatures per the derating curve. However, no IP rating is listed in the provided specs, so it should be used where the final system enclosure provides the required environmental protection.
