Frequently Asked Questions
Can I use the SD-25B-12 in a 24V or 36V industrial system that needs a 12V output rail?
It can fit that use case when the available input is within the listed 19-36VAC range and the 12V load stays within 2.1A and 25.2W. The output mode is constant voltage.
Is the SD-25B-12 suitable for a small 12V automation or control module?
Yes, for small 12V automation or control loads that require constant-voltage output up to 2.1A. Its rated output power is 25.2W.
Can this converter power a 12V embedded device from a higher input range?
It is designed for applications needing 12V output from a listed 19-36VAC input range. The connected 12V device must remain within 2.1A and 25.2W.
How does the SD-25B-12 compare with the other SD-25B models?
Within the SD-25B family, SD-25B-12 is 25.2W at 12V and 2.1A, SD-25B-24 is 26.4W at 24V and 1.1A, and SD-25B-5 is 25W at 5V and 5A. The listed differences are the output voltage, output current, and wattage by model.
Is the SD-25B-12 intended for indoor or outdoor environments?
The provided specs show an operating temperature range of -10°C to +60°C, but they do not include an IP rating. That means the temperature range is stated, while outdoor exposure protection is not.

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.
