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 equipment runs on 15V that the RSP-500-15 can support?

The RSP-500-15 delivers 501W at 15V and 33.4A, suitable for industrial transducer power supplies, certain servo amplifier auxiliary rails, and embedded systems using a 15V nominal bus. Its 1U form factor (230.0 × 127.0 × 40.5 mm) fits standard rack enclosures.

Is the RSP-500-15 rated for cold-climate indoor use?

Yes. The RSP-500-15 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-500-15 compare to the RSP-500-12 and RSP-500-24?

These three RSP-500 models share the 230.0 × 127.0 × 40.5 mm chassis and 85-264VAC input. The RSP-500-12 provides 500.4W at 41.7A, the RSP-500-15 provides 501W at 33.4A, and the RSP-500-24 provides 504W at 21A. Power output is consistent across the three; current rating decreases as voltage increases.

What active power conditioning does the RSP-500-15 include?

The RSP-500-15 includes built-in active PFC to improve input power quality. It weighs 1.3 kg and includes a 3-year warranty.
