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-35A in a small controller that needs both 5V logic and 12V support power?

Yes. The RD-35A is a dual output constant voltage supply with 5V and 12V outputs. The listed 5V output current is 4A and total power is 32W, so it fits lower-power control or embedded systems that need both rails.

Is the RD-35A suitable for compact automation hardware with limited mounting space?

It is well suited to compact enclosures because the housing is 99.0 x 82.0 x 36.0 mm and weighs 0.3 kg. With 32W total power and a 5V output rated at 4A, it fits lighter-duty industrial or embedded equipment that needs a small dual output supply.

Can the RD-35A be used in industrial equipment that sees vibration or warm cabinet conditions?

Yes. The specifications list 5G vibration resistance and an operating range of -25°C to +70°C. Those ratings make it suitable for enclosed industrial and automation equipment where vibration and internal heat are part of normal operation.

Is the RD-35A appropriate for outdoor installations?

An IP rating is not listed for this model, so it should be considered an indoor power supply or one that must be installed inside a protective enclosure. The operating temperature range is -25°C to +70°C, but no outdoor ingress protection is specified.

How does the RD-35A compare with the other RD family models listed here?

The RD-35A is one of the smaller models at 32W with a listed 5V output current of 4A. Other specified siblings are RD-35B at 35W with 5V 2.2A and 24V 1A, RD-3513 at 35.1W with 13.5V 1.3A and -13.5V 1.3A. Higher power models in the RD series include RD-50A, RD-50B, RD-65A, RD-65B, RD-85A, RD-85B, RD-125A, and RD-125B, which offer higher wattages and different voltage combinations.
