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-400-24-C in a 24V factory control enclosure?

Yes, if the enclosure's DC bus requires constant 24V and the connected load does not exceed 10.5A. Its 252W output makes it appropriate for higher-capacity 24V control and automation assemblies.

Is the RPS-400-24-C suitable for a 24V embedded system with several DC subsystems?

It can be suitable when the embedded system and all attached 24V subsystems stay within 10.5A total current draw. Because it is a constant-voltage model, it is intended for 24V DC equipment that expects a fixed-voltage source.

Can this model power a 24V industrial communications or edge device setup?

Yes, for 24V DC communications, edge, or control hardware that fits inside the 252W and 10.5A output limits. The 80-264VAC input is also useful where the upstream AC source may vary across installations.

Would the RPS-400-24-C fit a medical or laboratory platform that needs a 24V internal supply?

It is listed as a medical power supply with medical safety approval (IEC 60601-1, ANSI/AAMI ES60601-1, 2xMOPP) and earth leakage below 200μA. If the platform requires constant 24V DC and no more than 10.5A, the electrical rating aligns with that requirement.

How does the RPS-400-24-C differ from the other 24V versions in the same power class?

The RPS-400-24, RPS-400-24-C, RPS-400-24-SF, and RPS-400-24-TF all reach 400.8W at 16.7A with 25CFM airflow, built in on the SF and TF, while this -C and the base RPS-400-24 give 252W at 10.5A by convection. Physically, this RPS-400-24-C is 130.0 x 86.0 x 43.0 mm and 0.51 kg, the base RPS-400-24 is 127.0 x 76.2 x 35.0 mm and 0.39 kg, the SF version is 160.0 x 86.0 x 43.0 mm and 0.64 kg, and the TF version is 130.0 x 86.0 x 58.5 mm and 0.58 kg.

Is the RPS-400-24-C rated for outdoor or washdown environments?

The provided specs list an operating range of -30°C to +70°C, which supports a wide indoor temperature envelope. No IP rating is shown, so the listed data does not support exposed outdoor, washdown, or sealed-enclosure claims.
