Test conditions and notes9

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. 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 360mm*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. For charging related applications, please consult Mean Well for details.
7. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSP-200-2.5/-3.3/-4/-5/-7.5/-12/-13.5/-15)
8. 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).
9. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What systems use a 4V power supply like the RSP-200-4?

The RSP-200-4 delivers 4V at 40A (160W) and is suited for specialized logic rails in telecommunications line cards, certain DSP hardware platforms, DRAM termination buses, and custom embedded boards specifying a 4V supply. The 88–264VAC input is compatible with worldwide AC supplies.

How does the RSP-200-4 compare to the RSP-200-3.3 and RSP-200-5?

The RSP-200-3.3 delivers 3.3V/40A/132W. The RSP-200-4 delivers 4V/40A/160W. The RSP-200-5 delivers 5V/40A/200W. All three share the same 40A output current limit and 215.0 × 115.0 × 30.0 mm chassis. Wattage increases proportionally with voltage.

Is the RSP-200-4 appropriate for 1U rack panel installation?

Yes. At 215 × 115 × 30 mm and 0.72 kg, the RSP-200-4's 30 mm height suits 1U low-profile equipment. It is a component power supply mounted inside the final equipment using M4 threaded holes on the bottom and both sides.

What is the operating temperature range of the RSP-200-4?

The RSP-200-4 is rated from -30°C to +70°C ambient, identical to other RSP-200 models. No IP rating is specified; an enclosure is required for wet or dusty installation environments.

What certifications does the RSP-200-4 hold?

The RSP-200-4 is approved to UL62368-1, TÜV BS EN/EN62368-1, EAC TP TC 004, CCC GB4943.1, BSMI CNS15598-1 and AS/NZS 60950.1, and complies with EN55032 Class B emission and EN55035 immunity. BIS approval does not cover the 4V model.
