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 0.1ΞΌF & 47ΞΌF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 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 β€œEMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  7. 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-50-5 for a 5V industrial controller or logic board?

Yes, if the equipment requires 5V constant voltage and draws no more than 10A or 50W. That makes it suitable for many 5V control and logic applications in industrial or embedded systems.

Is the RS-50-5 suitable for powering a 5V embedded computer or development platform?

It can be a fit for 5V embedded hardware when the combined load stays within 10A and 50W. The wide 88-264VAC input also supports use in systems that need broad AC input compatibility.

Can this model power multiple 5V peripherals in one enclosure?

Yes, as long as the total 5V load remains at or below 10A and 50W. Its constant-voltage output makes it appropriate for grouped 5V electronics that share the same power requirement.

Would the RS-50-5 work in an industrial cabinet with vibration and limited space?

It is designed for 5G vibration and has a compact 99.0 x 97.0 x 36.0 mm form factor. That combination can be useful in tighter control cabinets where a 5V, 10A supply is needed.

Can the RS-50-5 be used outdoors or in high-temperature environments?

The specified operating range is -25C to +70C, so it supports a broad temperature window. No IP rating is provided here, so the specs do not establish outdoor or washdown suitability.
