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. 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-65-12 for 12V industrial controls, relays, or automation electronics?

It is a constant-voltage 12V supply with up to 5.42A output and 65W total power. That makes it suitable for 12V automation electronics when the full load stays within those electrical limits.

Is the RPS-65-12 suitable for 12V embedded systems or OEM equipment?

Yes, if the embedded or OEM system is designed for a regulated 12V rail and requires no more than 5.42A. Its compact 76.2 x 50.8 x 24.0 mm size and 0.11 kg weight also help in smaller assemblies.

Can this model be used in medical or laboratory devices that need 12V DC?

This power supply is medical safety approved and specified with extremely low leakage current. For medical or lab equipment that needs constant 12V output within 65W, those characteristics make it suitable for OEM integration.

Would the RPS-65-12 work for always-on control electronics where standby draw matters?

This model lists no-load power consumption below 0.1W, which is useful in designs where idle power matters. It still provides up to 12V and 5.42A when the equipment is operating under load.

Can the RPS-65-12 be used outdoors or in non-climate-controlled enclosures?

The operating temperature range is -30°C to +70°C, so the thermal range is broad. No IP rating is listed, so the unit itself does not define water or dust protection and would need that protection from the equipment enclosure.
