Test conditions and notes6

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 0.1uf & 47uf 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. 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 720mm*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)
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).

FAQ

What makes the RSP-1500-5 unusual compared to other RSP-1500 variants?

The RSP-1500-5 is rated at 1200W rather than 1500W, delivering 5V at 240A (1200W). The 5V output voltage results in very high current — 240A — while the total wattage is capped at 1200W by the current design. This makes it appropriate for high-current 5V bus systems such as large embedded computing farms, industrial LED display power rails, and distributed 5V logic systems requiring exceptional current capacity.

Can the RSP-1500-5 support parallel operation for N+1 redundancy?

Yes. The RSP-1500-5 has built-in active current sharing for up to 6000W or (3+1) units. With total current limited to rated current × number of units × 0.9, three units deliver up to 648A at 5V, with a fourth unit providing the +1 redundancy. Load balancing is automatic across the paralleled units.

How does the RSP-1500-5 compare to the RSP-1500-12 and RSP-1500-24?

RSP-1500 series: RSP-1500-5 (1200W/5V/240A), RSP-1500-12 (1500W/12V/125A), RSP-1500-15 (1500W/15V/100A), RSP-1500-24 (1512W/24V/63A), RSP-1500-27 (1512W/27V/56A), RSP-1500-48 (1536W/48V/32A). The RSP-1500-5 is the only variant under 1500W due to the 5V current ceiling. All variants share the 278.0 × 127.0 × 83.5 mm chassis and 90–264VAC input.

What is the operating temperature range of the RSP-1500-5?

The RSP-1500-5 operates from -20°C to +70°C ambient, with load derating at higher temperatures (the 5V model has its own, steeper curve in the derating chart). It has no IP rating and requires an enclosure for harsh environments.

What certifications does the RSP-1500-5 carry?

The RSP-1500-5 is approved to UL62368-1, CAN/CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1, BSMI CNS15598-1, AS/NZS62368.1 and EAC TP TC 004. CCC (China) is not listed on the RSP-1500 datasheet.
