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

Can the RSP-100-24 power 24V industrial sensors, actuators, or solenoid valves?

Yes. The RSP-100-24 provides 24V at 4.2A (100.8W) which covers a wide range of 24V DC field devices including proximity sensors, solenoid valves, and small actuators. Its 85–264VAC input supports both 110V and 230V AC supplies commonly found in industrial panels.

How does the RSP-100-24 compare to other RSP-100 voltage variants?

All RSP-100 variants share the 179.0 × 99.0 × 30.0 mm form factor, 85–264VAC input, and -30°C to +70°C temperature range. Voltage options with their output currents 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). The RSP-100-24 delivers 4.2A at 24V.

Is the RSP-100-24 appropriate for 24V embedded computing or single-board computers?

Yes. The RSP-100-24 can supply 24V at up to 4.2A to embedded computing platforms, HMI displays, and industrial PCs that operate on a 24V DC bus. Its low 30 mm height simplifies integration into compact control enclosures.

What is the temperature rating of the RSP-100-24 and how does that affect indoor use?

The RSP-100-24 is rated from -30°C to +70°C ambient; at higher ambient temperatures the output must be derated according to the sheet's derating curve. Standard indoor environments sit well inside this range. No IP rating is specified, so the unit requires an enclosure for protection against dust or moisture.

Does the RSP-100-24 include active PFC?

Yes. The RSP-100-24 features active power factor correction (PFC), which reduces harmonic disturbances on the AC supply. This is particularly relevant in industrial settings where multiple power supplies operate simultaneously on shared circuits or where utility requirements mandate PFC compliance.
