Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. Touch current was measured from primary input to DC output.
6. 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).
7. The power supply is considered a component which will be installed into a final equipment. All the ClassⅠ(with FG) EMC tests are executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The ClassⅡ (without FG) EMC tests are executed by mounting the unit on a 130mm*86.6mm 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 )

FAQ

Can I use the RPS-400-36-SF to power a 36V industrial machine subsystem?

Yes, if the subsystem requires constant 36V DC and draws no more than 11.2A. This model provides up to 403.2W with its built-in side fan, which suits many 36V industrial subsystems, controllers, and powered assemblies.

Is the RPS-400-36-SF appropriate for 36V medical instrumentation?

It is identified as a medical power supply with medical safety approval (IEC 60601-1, ANSI/AAMI ES60601-1, 2xMOPP) and earth leakage below 200μA. For medical instrumentation that needs 36V constant voltage up to 11.2A, its electrical rating is aligned with that use.

Can this model support a 36V automation cabinet or control enclosure?

It can support 36V automation equipment as long as the total load stays within 403.2W and 11.2A. The 80-264VAC input range is also useful where control cabinets may be deployed across different AC mains environments.

Would the RPS-400-36-SF work for a 36V test and measurement platform?

For bench or rack equipment that needs a fixed 36V DC rail, this supply offers constant voltage output with up to 11.2A available current. Its larger 160.0 x 86.0 x 43.0 mm size may matter when comparing it with shorter variants in the same power class.

What are the main 36V options around the RPS-400-36-SF in the RPS family?

This sheet lists four 36V versions: RPS-400-36 (PCB type), RPS-400-36-C (enclosed), RPS-400-36-TF (fan on top) and RPS-400-36-SF (fan on side). All reach 403.2W at 11.2A with 25CFM airflow, built in on the TF and SF, while the RPS-400-36 and -C give 252W at 7A by convection.

Is the RPS-400-36-SF meant for indoor or outdoor use?

The provided environmental data shows an operating temperature range of -30°C to +70°C, which supports demanding indoor operating conditions. No IP rating is listed, so the specs provided do not establish outdoor or water-exposed suitability.
