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-5 to power a 5V industrial controller from a 36-72V DC system?
Yes. This model is a constant-voltage DC-DC converter with a 36-72V input range and a regulated 5V output. Its 100W, 20A output is suited to 5V industrial control electronics that need higher current from a 36-72V source.
Is the SD-100C-5 a fit for 5V embedded computers or edge devices in automation panels?
It can be a fit when the equipment requires a steady 5V rail and the total load stays within 100W or 20A. The wide 36-72V input range is useful in embedded and automation systems built around higher-voltage DC buses. Its constant-voltage output is intended for electronics that expect fixed 5V input power.
Can this converter run multiple 5V PLC accessories or I/O modules from one supply?
It is intended for 5V loads as long as the combined demand does not exceed 100W or 20A. That makes it more suitable for grouped low-voltage control devices than a smaller 15W or 25W unit in the same series. The 36-72V input range also matches higher-voltage control cabinets and mobile DC platforms.
Is the SD-100C-5 suitable for outdoor or washdown locations?
No IP rating is listed for this model, so it is better suited to protected indoor enclosures rather than exposed outdoor or washdown locations. The stated operating temperature range is -10°C to +60°C, which helps define the ambient conditions it can handle. If the installation is outdoors, it would need additional enclosure protection appropriate to the site.
How does the SD-100C-5 compare with other 100W SD-series models?
Within the 100W class, the SD-100C-5 is rated for 100W, 5V, and 20A. Its same-group siblings are SD-100C-12 at 102W, 12V, 8.5A and SD-100C-24 at 100.8W, 24V, 4.2A, while the SD-100A-5, SD-100B-5, and SD-100D-5 are also 100W, 5V, 18A variants. Across the broader series, output options range from 5V to 48V and power ranges from 15W up to 1008W.
