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. Fan always on for 3.3~5V,Fan ON/OFF control for 12~48V.
6. 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 )
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

What industrial systems is the RSP-500-24 suited to power?

The RSP-500-24 outputs 24V at 21A (504W), matching the 24V DC bus used extensively in PLC systems, industrial robotics, and distributed I/O modules. Its 1U low-profile form factor (230.0 × 127.0 × 40.5 mm) supports rack and panel deployment.

What is the ambient operating range of the RSP-500-24?

The RSP-500-24 operates from -30°C to +70°C (refer to the derating curve). It is an enclosed type unit with UL62368-1, TÜV BS EN/EN62368-1, AS/NZS 62368.1, EAC, CCC, BSMI and BIS safety approvals.

How does the RSP-500-24 compare to the RSP-500-27 at similar voltages?

Both units share the 230.0 × 127.0 × 40.5 mm chassis and 85-264VAC input. The RSP-500-24 delivers 504W at 21A, while the RSP-500-27 delivers 502.2W at 18.6A. Power output is nearly identical; the RSP-500-27 provides a slightly higher voltage at lower current.

Does the RSP-500-24 include active PFC?

Yes. The RSP-500-24 includes built-in active PFC across its 85-264VAC input range. The unit weighs 1.3 kg and carries a 3-year warranty.
