Frequently Asked Questions
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, 18A 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 18A. 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 18A. 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 -15°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 18A. 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.

Not shipped.
Model: SD-50C-12Quantity: 1I was notified it was shipped the next day of ordering. Tracking shows no progress beyond label being created. I expected reasonable shipping time coming from Massachussetts. Maybe the seller neglects to give that information that it may be shipped from China. Don't be mislead!
Response from Power Supply Mall|2026-08-14Thank you for your feedback. Your order of 1 unit of the SD-50C-12 placed on August 3rd shipped via FedEx, tracking 383002421062, and was delivered to your location on August 13th. The delivery took 8 business days, which is longer than our typical timeframe. This model is less commonly stocked, so we had to arrange it from another warehouse. Most of our power supplies ship from our main location, but this particular model required sourcing from an alternate facility.
