Frequently Asked Questions
Can I use the SD-100D-5 to power 5V embedded controllers from a 72-144V DC source?
Yes. This unit converts 72-144V input to regulated 5V constant-voltage output. Its 100W rating and 18A output current make it suitable for higher-current 5V embedded and control electronics on high-voltage DC systems.
Is the SD-100D-5 suitable for 5V industrial computers or data acquisition hardware?
It is a fit when the equipment requires 5V input and the total load stays within 100W or 18A. The wide 72-144V input range is useful in systems built around higher-voltage DC buses. Its constant-voltage output is intended for electronics that need a stable 5V supply.
Can this model power several 5V automation devices from one high-voltage DC bus?
It can support multiple 5V devices if their combined demand remains at or below 100W and 18A. That makes it practical for grouped 5V control, monitoring, or processing electronics fed from a 72-144V source. It is better suited to moderate-power 5V loads than the smaller 15W or 25W units in the same series.
Can the SD-100D-5 be used in outdoor equipment enclosures?
No IP rating is listed for this converter, so it is generally better for protected indoor enclosures than direct outdoor exposure. The operating temperature range is -15°C to +60°C. If it is placed in outdoor equipment, the surrounding enclosure would need to provide the environmental protection.
What distinguishes the SD-100D-5 from the other SD-100D models?
The difference is the output class within the same family. SD-100D-5 is 100W at 5V and 18A, SD-100D-12 is 102W at 12V and 8.5A, and SD-100D-24 is 100.8W at 24V and 4.2A. All three stay near the 100W range while targeting different output voltages and current levels.

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.
