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-50-15 for 15V instrumentation or analog control equipment?

Yes, if the equipment requires constant 15V DC and the load stays within 3.4A and 51W. It is a practical match for industrial electronics and bench or embedded systems built around a 15V rail.

Is the RS-50-15 suitable for a 15V embedded controller or test fixture?

It can be, because it delivers constant 15V output up to 3.4A with 51W total available power. That fits 15V embedded assemblies and fixture electronics that are rated within those limits.

Can this model power 15V automation modules inside a control enclosure?

It is intended for constant-voltage 15V loads and can support them up to 3.4A and 51W. For automation hardware that specifies 15V DC input, the key check is keeping the total draw inside the unit's rated output.

How does the RS-50-15 compare with the other 15V RS series supplies?

The listed 15V models are RS-15-15 at 15W and 1A, RS-25-15 at 25.5W and 1.7A, RS-35-15 at 35W and 2.4A, RS-50-15 at 51W and 3.4A, RS-75-15 at 75W and 5A, RS-100-15 at 105W and 7A, and RS-150-15 at 150W and 10A. The RS-50-15 sits in the middle of that 15V range for output capacity.

Is the RS-50-15 rated for outdoor use or only protected environments?

The specs list an operating temperature range of -25Β°C to +70Β°C and 5G vibration resistance. No IP rating is listed, so the published data supports protected indoor use but does not confirm outdoor or washdown suitability.
