Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Touch current was measured from primary input to DC output.
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).
8. 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 )

FAQ

Can I use the RPS-45-5 for a 5V embedded system or industrial controller?

Yes, it provides constant-voltage 5V output with up to 8A available and a 40W maximum output. That makes it suitable for 5V embedded and industrial control electronics that stay within those limits.

Is the RPS-45-5 suitable for powering 5V USB-style logic boards or interface electronics inside equipment?

It can support 5V logic and interface sections when the total load does not exceed 8A or 40W. Buyers should match the equipment to the regulated 5V output rather than treating it as a multi-voltage supply.

Can this model be used in medical or lab devices that need a 5V internal power rail?

Yes, it is designed as a 5V constant-voltage supply and is rated for up to 8A. It is also medical safety approved and features extremely low leakage current, which can matter in medical and laboratory equipment.

Is the RPS-45-5 a good choice for compact 5V automation assemblies with limited space?

Yes, the small 76.2 x 50.8 x 24.0 mm footprint and 0.11 kg weight help in compact enclosures. Electrically, it delivers up to 40W at 5V for low-voltage control and logic loads.

How does the RPS-45-5 compare with other RPS-45 models?

The RPS-45 range includes 3.3V at 26.4W and 8A, 7.5V at 40.5W and 5.4A, 12V at 45.6W and 3.8A, 15V at 45W and 3A, 24V at 45.6W and 1.9A, and 48V at 45.1W and 0.94A. The RPS-45-5 is the 5V version and is rated at 40W with up to 8A output current.

Can the RPS-45-5 be used in outdoor equipment or only indoors?

The operating temperature range is -30C to +70C, so it can work across a wide temperature span in protected equipment. No IP rating is provided, so it is better suited to indoor or enclosed installations than exposed outdoor use.
