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-25-5 to power a 5V single-board computer or embedded controller?

Yes, if the equipment needs a 5V constant voltage supply and the total load does not exceed 5A or 25W. That makes it suitable for many 5V embedded controllers, processor boards, and support electronics within that power budget.

Is the RS-25-5 suitable for 5V industrial logic, I/O, or communications electronics?

It is intended for 5V constant voltage loads and can deliver up to 5A. For industrial logic or communications electronics designed for a regulated 5V rail, it is a fit if the total demand stays within 25W.

Can this power supply run multiple low-power 5V modules in one enclosure?

It can, provided the combined load remains at or below 5A and 25W. Its compact 78.0 x 51.0 x 28.0 mm size also helps when several low-power modules share limited enclosure space.

Would the RS-25-5 work in compact automation or test equipment that needs a 5V rail?

It is a reasonable choice for compact automation or bench equipment that needs 5V DC and stays within 5A output current. The 88-264VAC input range also supports use across common global AC supply ranges.

Can the RS-25-5 be used in outdoor or washdown environments?

The operating temperature range is specified as -20 degrees C to +70 degrees C, so the thermal range is defined. No IP rating is listed, which means the provided specs do not confirm protection for outdoor exposure, washdown, or dust-heavy environments.

How does the RS-25-5 compare with the other RS-25 models?

The RS-25 lineup includes RS-25-3.3 at 19.8W, 3.3V, 6A; RS-25-5 at 25W, 5V, 5A; RS-25-12 at 25.2W, 12V, 2.1A; RS-25-15 at 25.5W, 15V, 1.7A; RS-25-24 at 26.4W, 24V, 1.1A; and RS-25-48 at 27.36W, 48V, 0.57A. Compared with the higher-voltage versions, the 5V model provides higher output current at 5A.
