Test conditions and notes6
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 5. Strongly recommended that external output capacitance should not exceed 5000uF.(Only for: RSP-100-3.3/-5/-7.5)
  6. 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

Is the RSP-100-12 suitable for powering 12V industrial control panels or PLC systems?

Yes. The RSP-100-12 delivers 12V at up to 8.5A (102W total), which is well suited for 12V DC control panels, PLC rack power, and embedded automation systems. Its universal input range of 85–264VAC means it operates on both 110V and 230V mains without reconfiguration. The operating temperature range of -30°C to +70°C also suits factory floor environments.

Can the RSP-100-12 be used in IT rack enclosures?

The datasheet does not specify rack mounting; the RSP-100-12 measures 179.0 × 99.0 × 30.0 mm and is installed inside the equipment or enclosure using its M4 mounting holes. At 102W output and 0.52 kg, it is suitable for powering 12V rack accessories, network switches, or embedded equipment where 12V power is required.

What are the differences between RSP-100 voltage variants?

All RSP-100 variants share the same 179.0 × 99.0 × 30.0 mm chassis and 85–264VAC input. The voltage options and their output current ratings are: RSP-100-3.3 (66W/3.3V/20A), RSP-100-5 (100W/5V/20A), RSP-100-7.5 (101.25W/7.5V/13.5A), RSP-100-12 (102W/12V/8.5A), RSP-100-13.5 (101.25W/13.5V/7.5A), RSP-100-15 (100.5W/15V/6.7A), RSP-100-24 (100.8W/24V/4.2A), RSP-100-27 (102.6W/27V/3.8A), RSP-100-48 (100.8W/48V/2.1A). Higher voltage variants deliver lower current at similar wattage. Select the variant matching your load's nominal voltage.

What is the operating temperature range of the RSP-100-12, and does it suit outdoor enclosures?

The RSP-100-12 is rated for -30°C to +70°C operation, with output derating at higher ambient temperatures according to the derating curve. It does not carry an IP rating and humidity must stay within 20–90% RH non-condensing, so it is not suited to outdoor or wet locations. Install it inside dry indoor industrial or commercial equipment.

What certifications does the RSP-100-12 hold?

The RSP-100-12 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. These cover the US, Europe, China, Taiwan, India and Russia/CIS markets, simplifying compliance for multi-region product deployments.
