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-100C-5 to power a 5V embedded controller from a 36V or 48V DC source?
Yes, this converter accepts 33.6~62.4V input and provides a constant-voltage 5V output. With up to 20A and 100W available, it suits 5V embedded controllers, industrial computing devices, and logic systems that operate within that load level.
Is the RSD-100C-5 a good choice for generating 5V power inside telecom or automation cabinets?
Yes, a nominal 48V DC source fits inside the 33.6~62.4V input range. The converter steps that down to 5V constant voltage with up to 20A and 100W for 5V electronics used in control, communications, or monitoring equipment.
Can this model support 5V control electronics in vibration-prone industrial equipment?
The specs list 10~500Hz, 5G vibration with IEC61373 shock and vibration compliance, which makes it relevant for equipment that sees mechanical stress. It is intended for 5V constant-voltage loads up to 20A and 100W from a 33.6~62.4V input supply.
Will the RSD-100C-5 handle cold or hot industrial 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 stated in the provided data, so environmental protection against water or dust would need to come from the enclosure rather than the converter itself.
What is the difference between the RSD-100C-5 and other 100W RSD-100 variants?
The 5V versions in the RSD-100 family are RSD-100B-5, RSD-100C-5, and RSD-100D-5, each rated at 100W and 20A. Related 12V models are 100.8W and 8.4A, and related 24V models are 100.8W and 4.2A; the C version is the member of the 33.6~62.4V input group.
