Test conditions and notes5

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. 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)
5. 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 systems benefit from the RSP-2400-48's 48V, 50A output?

The RSP-2400-48 provides 2400W at 48V with 50A output, suitable for powering telecom DC power systems, PoE aggregation equipment, and high-capacity battery charging applications. The 48V bus is a common standard in telecommunications and data center power distribution.

Is the RSP-2400-48 suitable for low-temperature environments?

The RSP-2400-48 operates down to -20°C, making it appropriate for heated indoor enclosures in cold climates but not for unheated outdoor installations. Its upper limit is +70°C, matching the range of other RSP-2400 series units.

How does the RSP-2400-48 compare to the RSP-2000-48 and RSP-3000-48?

The RSP-2000-48 provides 2000.4W and 100A on a wide 90-264VAC input. The RSP-2400-48 steps up to 2400W and 50A, and the RSP-3000-48 reaches 3000W and 62.5A — both requiring a narrower 180-264VAC input. All three share 48V output; the RSP-2000-48 alone supports low-line AC.

What efficiency and paralleling capability does the RSP-2400-48 offer?

The RSP-2400-48 achieves up to 91.5% efficiency and supports 2+1 active current sharing for N+1 redundancy. It weighs 3.3 kg and measures 278.0 × 177.8 × 63.5 mm.
