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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation. (In order to meet tolerance, it is recommended that CH1 load >15% rated current for A type and CH1 load > 10% rated current for B type.)
  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 “EMI 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 RD-35B for a compact system that needs 5V control power and a 24V rail?

Yes. The RD-35B is a dual output constant voltage supply with 5V and 24V outputs. Its listed 5V output current is 2.2A and total power is 35W, which suits lower-power embedded, control, or automation assemblies using both voltages.

Is the RD-35B a fit for small industrial or embedded devices with universal AC input requirements?

It can fit those applications because it accepts 88-264VAC input and provides dual constant voltage outputs. The unit is rated at 35W total power and comes in a compact 99.0 x 82.0 x 36.0 mm package. That combination works well for smaller control hardware using 5V and 24V rails.

Can the RD-35B be used in enclosed equipment that experiences vibration or temperature variation?

Yes. The listed features include 5G vibration resistance and operation up to +70°C. Its operating temperature range is -25°C to +70°C, which supports use in protected industrial enclosures with changing ambient conditions.

Is the RD-35B rated for indoor or outdoor environments?

These specifications do not provide an IP rating, so it should be used indoors or inside a protective enclosure rather than in exposed outdoor conditions. The temperature range is -25°C to +70°C, but no ingress protection is stated.

What distinguishes the RD-35B from other RD series models in the same list?

The RD-35B is a 35W model with a listed 5V output current of 2.2A and 24V output current of 1A. Other specified siblings are RD-35A at 32W with 5V 4A and 12V 1A, RD-3513 at 35.1W with 13.5V 1.3A and -13.5V 1.3A, RD-50A at 54W with 5V 6A, RD-50B at 53.6W with 5V 4A, RD-65A at 66W with 5V 6A, RD-65B at 68W with 5V 4A, RD-85A and RD-85B at 88W with 5V 8A, RD-125A at 130.9W with 5V 7.7A, and RD-125B at 133.4W with 5V 4.6A.
