Frequently Asked Questions
Can I use the SD-100B-5 to power 5V industrial controllers or embedded electronics from a 19-36V source?
Yes, this model delivers 5V constant voltage output up to 18A with a 100W rating. It is appropriate for 5V embedded or control electronics when the source feeding the converter stays within 19-36V.
Is the SD-100B-5 suitable for 5V logic-heavy systems with higher current demand?
It is better suited to 5V applications that need more current than the 12V or 24V versions because this model is rated for 18A at 5V. The output remains constant voltage, which is typical for digital and embedded loads that expect a fixed 5V rail.
Can the SD-100B-5 be used for 5V automation interfaces, industrial computing boards, or communications modules?
It can fit 5V industrial and embedded subsystems that need regulated output and stay within 18A and 100W. That makes it a practical choice for denser 5V electronics loads than models intended for 12V or 24V outputs.
Is the SD-100B-5 intended for outdoor environments?
The stated operating temperature range is -15°C to +60°C, but no IP rating is listed in the provided specs. On that basis, outdoor or exposed-environment suitability is not defined, so it is best considered for protected indoor enclosures within the stated temperature range.
How does the SD-100B-5 compare with the other SD-100 output variants?
The 5V SD-100 models SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 are rated at 100W and 18A. The 12V versions SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12 are 102W and 8.5A, while the 24V versions SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 are 100.8W and 4.2A.

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.
