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-12 to derive 12V power from a 72V, 96V, or 110V DC system?
Yes, this model accepts 67.2~143V input and provides a constant-voltage 12V output. With up to 8.4A and 100.8W, it is suitable for 12V control, monitoring, and embedded loads on higher-voltage DC systems within that range.
Is the RSD-100D-12 suitable for high-voltage battery or DC bus automation equipment that needs 12V controls?
Yes, the 67.2~143V input range is intended for higher-voltage DC bus applications. It converts that input to 12V constant voltage at up to 8.4A and 100.8W for automation electronics that need a lower-voltage control rail.
Can this converter be used in railway, mobile, or industrial equipment with vibration?
The specs list 10~500Hz, 5G vibration with IEC61373 shock and vibration compliance, which supports use in equipment where mechanical vibration is a design factor. Its output remains 12V constant voltage with 8.4A and 100.8W available from a 67.2~143V input source.
Is the RSD-100D-12 intended for exposed outdoor environments?
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). No IP rating is listed in the provided specs, so it should be treated as a converter for protected enclosures rather than exposed outdoor installation without additional housing.
How does the RSD-100D-12 compare with other 100W RSD-100 models?
In the 100W RSD-100 group, the 12V models are RSD-100B-12, RSD-100C-12, and RSD-100D-12, all rated at 100.8W and 8.4A. The same family also includes 24V versions at 100.8W and 4.2A and 5V versions at 100W and 20A; the D model is the high-input variant with a 67.2~143V input range.
