Frequently Asked Questions
Can I use the SD-15B-12 to supply a small 12V automation load from an 18-36 input source?
Yes, this model is built for a wider 18-36 input range and provides a constant 12V output at up to 1.25A. Its 15W rating suits lower-power 12V automation, embedded, or industrial auxiliary loads within that limit.
Is the SD-15B-12 appropriate for a 24V-class control system that needs a small regulated 12V rail?
It can be appropriate when the available source is within the 18-36 input range and the downstream device needs 12V constant voltage. The output is limited to 15W and 1.25A, so it is intended for smaller 12V devices rather than heavier loads.
Can this converter power a compact 12V HMI accessory, relay interface, or control board?
This converter is better suited to low-power 12V accessories or control boards that stay within 1.25A output current. Its compact 78.0 × 51.0 × 28.0 mm size and 0.18 kg weight also help where panel space is limited.
Is the SD-15B-12 suitable for outdoor environments or only indoor enclosures?
The operating temperature range is -20°C to +85°C, which supports a broad temperature window. No IP rating is listed in the provided specifications, so the product data does not confirm outdoor, wet-location, or washdown use.
How does the SD-15B-12 differ from the other SD-15B models?
The SD-15B family includes SD-15B-5 at 15W, 5V, 3A; SD-15B-12 at 15W, 12V, 1.25A; and SD-15B-24 at 15W, 24V, 0.62A. All three share the 18-36 input range, constant voltage mode, -20°C to +85°C operating temperature, 78.0 × 51.0 × 28.0 mm dimensions, 0.18 kg weight, EAC certification, and a 3-year warranty.

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.
