Test conditions and notes8

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. Please refer to "Derating curve".
8. The power supply is considered a component which will be installed into a final equipment. All EMC tests are 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."

FAQ

Can the RPS-500-48-TF power a 48V industrial PC, controller, or automation subsystem?

It can be used for 48V equipment when the total demand does not exceed 10.4A and 499.2W. As a constant voltage supply, it is intended for 48V loads rather than applications that require a different output voltage.

Is this model a fit for high-power 48V embedded or communications hardware?

Yes, it is a 48V constant voltage power supply rated for up to 10.4A. That gives it 499.2W of available output for embedded, communications, or control hardware built around a 48V input rail.

Can I use the RPS-500-48-TF in a medical electronics platform that needs 48V output?

This model is medical safety approved and is specified with low leakage current (earth leakage <220μA, touch current <100μA). It is intended for 48V medical electronics or related equipment as long as the load remains within 10.4A and 499.2W.

Is the RPS-500-48-TF okay for outdoor cabinets or exposed factory areas?

The provided specs do not list an IP rating, so it is better treated as an indoor or enclosed-unit power supply rather than one for exposed outdoor service. Its operating temperature range is -30°C to +70°C with derating at higher temperatures, but that does not replace a stated ingress-protection rating.

Why would someone choose the RPS-500-48-TF over another 48V 500W form factor?

A key selection point is its 130 x 86 x 58.5 mm size with a built-in top fan, a shorter footprint than the 160 mm SF version, and 0.58 kg weight while still providing 48V, 10.4A, and 499.2W. It also supports a wide 80-264VAC input range.
