Frequently Asked Questions
Can I use the SD-25B-5 for a 5V embedded controller or single-board computer in industrial equipment?
Yes, it provides 5V constant voltage output up to 5A with 25W total power available. That makes it suitable for low-voltage embedded electronics that need a regulated 5V rail from a 19-36V input source.
Is the SD-25B-5 a fit for powering 5V logic, I/O boards, or communication modules?
It can support 5V control electronics as long as the total load stays within 5A and 25W. This makes it a practical choice for compact logic boards, interface modules, and similar low-power electronics rather than larger 5V systems.
Can this model be used in a 24V-class control cabinet when the load needs 5V?
It is designed for installations where the available input stays within 19-36V and the output requirement is 5V constant voltage. With up to 5A output current, it fits modest 5V embedded and automation electronics within a 25W budget.
What are the differences between the SD-25B-5 and the other SD-25B versions?
The SD-25B series includes SD-25B-5 at 25W, 5V, 5A; SD-25B-12 at 25.2W, 12V, 2.1A; and SD-25B-24 at 26.4W, 24V, 1.1A. All three share the same 19-36V input range in this series grouping.
Can the SD-25B-5 be used outdoors or in unprotected environments?
The provided specs do not show an IP rating, so there is no stated basis for outdoor exposure or direct moisture exposure. Its operating temperature range is -10°C to +60°C, so it is better suited to protected indoor equipment spaces that stay within that range.

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.
