Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 24,48,110VDC 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. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-100-5 / -12)
- 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. 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 I use the RSD-100D-24 to power a 24V industrial controller or HMI?
Yes, if the controller or HMI needs a constant 24V supply and draws no more than 4.2A. This converter is rated for 100.8W total output, so it fits lower-power 24V industrial control loads within that limit.
Is the RSD-100D-24 suitable for 24V embedded or automation electronics inside a vehicle or mobile equipment cabinet?
It can fit 24V embedded and automation loads that need constant voltage and stay within 4.2A and 100.8W. The specs also list 5G vibration with IEC61373 shock and vibration compliance, which is relevant for equipment exposed to movement or mechanical vibration.
Can this converter run a 24V sensor, relay, or control subsystem from a higher-voltage DC source?
It is intended for applications that need 24V output from a 67.2~143V input range. As long as the connected 24V subsystem stays within the 4.2A output current and 100.8W power rating, it matches that type of control-duty use.
Is the RSD-100D-24 appropriate for outdoor or harsh-temperature use?
It operates from -40°C to +55°C without derating, and up to +70°C at 60% load by free air convection or at full load when mounted on an external base plate (EN50155 TX class). However, no IP rating is listed in the provided specs, so outdoor or washdown suitability is not established by this product data alone.
How does the RSD-100D-24 compare with other RSD 100W-class outputs?
Within the listed 100W-class siblings, the 5V versions are 100W at 20A, the 12V versions are 100.8W at 8.4A, and the 24V versions are 100.8W at 4.2A. In the D group specifically, RSD-100D-5 is 100W 5V 20A, RSD-100D-12 is 100.8W 12V 8.4A, and RSD-100D-24 is 100.8W 24V 4.2A.
