Frequently Asked Questions
Can I use the SD-25C-12 to run a small 12V control device from a 36-72V source?
Yes, it is built for applications where the input stays within 36-72V and the load needs 12V constant voltage output. The available output is 2.1A and 25.2W, so it fits smaller 12V control and embedded loads rather than heavier 12V equipment.
Is the SD-25C-12 suitable for 12V relays, sensors, or alarm/control electronics in industrial systems?
It can support low-power 12V electronics as long as the total demand stays within 2.1A and 25.2W. That makes it appropriate for compact industrial control, signaling, or embedded support circuits that need regulated 12V output.
Can this converter power a small 12V fan or accessory in a telecom or automation cabinet?
It can be used for smaller 12V loads when the source voltage is within 36-72V and the load stays under 2.1A. The 25.2W output rating means it is intended for lighter-duty 12V accessories, not high-draw 12V devices.
How does the SD-25C-12 compare with the other SD-25C models?
The SD-25C family includes SD-25C-5 at 25W, 5V, 5A; SD-25C-12 at 25.2W, 12V, 2.1A; and SD-25C-24 at 26.4W, 24V, 1.1A. These models share the same 36-72V input range and differ by output voltage, current, and rated power.
Is the SD-25C-12 rated for outdoor conditions?
No IP rating is provided in the listed specs, so the product data does not support treating it as an outdoor-rated converter. The specified operating temperature range is -10°C to +60°C, which points to use in protected environments that remain within that temperature span.

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.
