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 230mm*230mm 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-15-5 for a 5V embedded controller or development board in industrial equipment?

Yes, this unit provides constant-voltage 5V output up to 3A. It fits 5V embedded electronics, controller boards, and small industrial logic assemblies that stay within its 15W rating.

Is the RS-15-5 suitable for powering USB-class 5V electronics inside a machine or kiosk?

It can be appropriate for internal 5V electronics when the total load does not exceed 3A. The main selection points are its 5V output (adjustable 4.75-5.5V) and 15W maximum power.

Can this model support 5V sensor interfaces or automation I/O modules?

It is a reasonable choice for 5V sensor interface boards, compact I/O modules, and low-power automation electronics that need constant-voltage 5V power. Capacity is limited to 3A, so it is best for lighter 5V loads rather than larger systems.

Is the RS-15-5 useful in equipment that sees vibration or elevated cabinet temperatures?

The specifications list 5G vibration resistance and operation up to +70Β°C with derating per the derating curve. That makes it relevant for protected industrial enclosures where a small 5V, 15W supply is needed and environmental stress is a concern.

Can the RS-15-5 be used in outdoor equipment?

The rated operating temperature is -20Β°C to +70Β°C, with output derating at higher ambient temperatures, so the thermal range is broad for indoor equipment use. The provided specs do not show an IP rating, so it is better matched to protected indoor installations rather than exposed outdoor locations.
