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 0.1μF & 47μF 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. 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. Strongly recommended that external output capacitance should not exceed 5000uF.(Only for: RSP-100-3.3/-5/-7.5)
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 embedded or industrial loads can the RSP-100-5 power?

The RSP-100-5 delivers 5V at 20A (100W) and is suited for 5V DC logic buses, Raspberry Pi clusters, industrial microcontroller panels, USB charging banks, and relay control boards. The 85–264VAC universal input means no external transformer is required on either 110V or 230V mains.

How does the RSP-100-5 compare to the RSP-100-3.3 and RSP-100-12 at the lowest voltages?

The RSP-100-3.3 delivers 3.3V at 20A (66W), the RSP-100-5 delivers 5V at 20A (100W), and the RSP-100-12 delivers 12V at 8.5A (102W). The 3.3V variant is limited to 66W by its 20A rating; the 5V and higher-voltage variants achieve approximately 100W. All use the same 179.0 × 99.0 × 30.0 mm chassis.

Is the RSP-100-5 suitable for use in rack-mounted test and measurement equipment?

Yes. Test and measurement instruments are among the applications listed on the datasheet, and its 179.0 × 99.0 × 30.0 mm size (30 mm height) suits compact equipment. It delivers 100W at 5V with active PFC, suitable for 5V instrumentation front-ends, data acquisition modules, and other test equipment drawing up to 20A at 5V.

What temperature range does the RSP-100-5 support?

The RSP-100-5 operates from -30°C to +70°C ambient, with output derating at higher temperatures according to the derating curve. This covers most indoor industrial environments including cold rooms. No IP rating is stated, so it must be installed in an enclosure that keeps it dry (20–90% RH non-condensing).

What certifications cover the RSP-100-5?

The RSP-100-5 is approved to UL62368-1, TÜV BS EN/EN62368-1, BS EN/EN61558-1 and -2-16, CCC GB4943.1, BSMI CNS15598-1, EAC TP TC 004 and BIS IS13252. This spans the US, Europe, China, Taiwan, India and the Eurasian Economic Union, supporting multi-region product qualification.
