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-35-12 for a 12V industrial control panel or automation enclosure?

Yes, if the panel components need a constant 12V DC supply and the total load stays within 36W and 3A. Its compact 99.0 Γ— 82.0 Γ— 36.0 mm size also helps in smaller control enclosures.

Is the RS-35-12 suitable for powering 12V embedded systems or industrial electronics?

It is a fit for embedded or industrial electronics that require regulated 12V DC and draw no more than 3A from a 36W supply. The wide 88-264VAC input is useful when the equipment may be deployed across different AC mains environments.

Can this 12V power supply run small 12V HMI accessories, relays, or control devices?

It can support small 12V control devices, relay assemblies, or HMI-related accessories when their combined demand remains at or below 36W and 3A. This model is constant voltage, so it is intended for equipment designed for a 12V DC source.

Is the RS-35-12 intended for indoor or outdoor use?

The provided specs list an operating temperature range of -25Β°C to +70Β°C, but no IP rating is provided. Without an IP rating, it is better suited to protected indoor or enclosed equipment use rather than exposed outdoor conditions.

How does the RS-35-12 compare with other 35W Mean Well RS models?

Within the 35W RS group, the options are RS-35-3.3 at 3.3V and 7A, RS-35-5 at 5V and 7A, RS-35-12 at 12V and 3A, RS-35-15 at 15V and 2.4A, RS-35-24 at 24V and 1.5A, and RS-35-48 at 48V and 0.8A. The main difference between them is the output voltage and matching current rating.
