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-12 to derive 12V control power from a 36-72V DC bus?
Yes, this converter is designed for a 36-72V input range and provides regulated 12V constant voltage output. With 8.5A output current and 102W power, it fits moderate 12V control and automation loads on higher-voltage DC systems.
Is the SD-100C-12 suitable for 12V industrial HMIs, monitoring devices, or communications equipment on 48V-class systems?
It can be a fit where the source falls inside the 36-72V input range and the load needs 12V constant voltage. Its 102W and 8.5A output rating suits moderate-power 12V electronics rather than large 12V current draws.
Can the SD-100C-12 power 12V embedded subsystems in automation or transport equipment with a higher-voltage DC source?
This model is intended for 12V loads that need regulated output from a 36-72V input source. The 2:1 wide input range supports higher-voltage DC platforms, while the 8.5A and 102W rating define the usable load size.
Is the SD-100C-12 rated for exposed outdoor service?
The available specs list an operating temperature range of -10°C to +60°C for the SD-100C series, but no IP rating is provided. That means the stated data supports temperature evaluation, but not outdoor ingress protection claims.
How does the SD-100C-12 compare with other SD-100 family outputs?
In the SD-100 range, the 12V versions SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12 are each rated at 102W and 8.5A. The 24V versions SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 are 100.8W and 4.2A, and the 5V versions SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 are 100W and 18A.
