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 0.1uf & 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. Please contact MEANWELL for 320~370VDC application.
6. 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)
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 applications is the RSP-2000-48 suited for?

The RSP-2000-48 delivers 2016W at 48V with a 42A output, making it well-suited for powering DC motor drives, industrial automation controllers, and high-density server rack infrastructure. Its -35°C to +70°C operating range supports demanding factory and data center environments.

Is the RSP-2000-48 rated for operation in cold environments?

Yes. The RSP-2000-48 operates from -35°C to +70°C. It is intended for indoor enclosed installations and carries certifications including UL, CSA, TÜV, BSMI, AS/NZS, BIS, and EAC.

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

Within the 48V RSP line, the RSP-2000-48 provides 2016W and 42A from a 90-264VAC input. The RSP-2400-48 and RSP-3000-48 are higher wattage models in the series. The RSP-2000-48 accepts the full 90-264VAC range, making it a flexible choice where wide-range AC input is needed.

Does the RSP-2000-48 support paralleling for higher current output?

Yes. The RSP-2000-48 features active current sharing, rated for up to 3+1 units in parallel. This allows system designers to scale output current beyond the single-unit 42A rating while using a built-in N+1 redundancy configuration.

What is the efficiency of the RSP-2000-48?

The RSP-2000-48 achieves efficiency up to 92% and includes built-in active PFC. The unit weighs 1.95 kg and measures 295.0 × 127.0 × 41.0 mm, making it a compact choice for high-wattage 48V applications.
