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. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 0% to 100% rated load.
- 6. 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 )
- 7. 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).

FAQ
Can I use the RS-50-48 for a 48V industrial control device or automation module?
Yes, this model is a constant-voltage 48V supply rated for 52.8W and 1.1A. It fits 48V industrial or automation loads that stay within that output range.
Is the RS-50-48 a good fit for a small 48V embedded system or communications enclosure?
It can be, as long as the equipment requires 48V constant voltage and does not exceed 1.1A or 52.8W. Its compact 99.0 x 97.0 x 36.0 mm size can also help where enclosure space is limited.
Can this power supply run a 48V automation accessory in a vibration-prone machine area?
This unit is specified to withstand 5G vibration, so it is better suited to industrial equipment than a basic open-frame supply with no vibration detail listed. The load still needs to match its 48V, 1.1A, and 52.8W output limits.
Would the RS-50-48 work for a low-power 48V control panel device?
Yes, it is intended for constant-voltage 48V applications and provides up to 1.1A. That makes it a practical option for lower-power 48V panel devices rather than larger 48V loads.
Is the RS-50-48 suitable for outdoor use or harsh temperature conditions?
The operating temperature range is -25C to +70C, so it covers a wide temperature span. No IP rating is listed in the provided specs, so outdoor suitability should not be assumed from this data alone.
