Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 12,24,48,96VDC 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. 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 )
- 5. 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 SD-100C-24 for 24V PLC, sensor, or automation loads on a 36-72V DC bus?
Yes, it is a constant voltage DC-DC converter that accepts 36-72V input and delivers 24V output up to 4.2A. Its 100.8W rating makes it suitable for moderate 24V control and automation loads on higher-voltage DC systems.
Is the SD-100C-24 suitable for 24V industrial communications or embedded equipment fed from nominal 48V systems?
It can be used where the available source is within 36-72V and the downstream hardware needs regulated 24V constant voltage. The usable load limit is 4.2A and 100.8W.
Can the SD-100C-24 power 24V control subsystems inside industrial cabinets or mobile equipment?
This model is suited to enclosed 24V subsystems that need a stable constant voltage output from a higher-voltage DC input. The 2:1 wide input range of 36-72V helps match platforms that do not stay at one fixed input level.
Is the SD-100C-24 appropriate for outdoor enclosures or harsh locations?
The stated operating temperature range is -15°C to +60°C, but the provided specs do not include an IP rating. Based on that, the temperature range is defined, while ingress protection for exposed outdoor use is not.
What is the output-positioning of the SD-100C-24 within the SD-100 series?
The 24V SD-100 models SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 are each rated at 100.8W and 4.2A. The 12V versions SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12 are 102W and 8.5A, while the 5V versions SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 are 100W and 18A.
