Frequently Asked Questions
Can I use the SD-15A-12 to power a 12V industrial sensor or small control accessory from a 9-18 input source?
Yes, this model is a constant voltage DC-DC converter with a 12V output and 1.25A output current. Its 15W rating and 9-18 input range fit low-power 12V industrial sensors, control accessories, or embedded devices that stay within those limits.
Is the SD-15A-12 suitable for a compact embedded 12V electronics load in a mobile or battery-based system?
It can be a fit when your source stays within the 9-18 input range and the load needs regulated 12V constant voltage output. With 15W available in a 78.0 × 51.0 × 28.0 mm package, it is aimed at compact low-power 12V loads rather than higher-current equipment.
Can this converter support a low-power 12V automation device in a control enclosure?
This unit is intended for low-power 12V automation or control devices that draw no more than 1.25A at 12V. The 15W output rating and 1.5~2KVAC isolation by models make it more appropriate for small auxiliary loads than for larger 12V control hardware.
Is the SD-15A-12 rated for outdoor or harsh-temperature use?
The operating temperature range is -20°C to +85°C, so the temperature spec is broad for industrial environments. No IP rating is listed in the provided specs, so outdoor exposure or washdown suitability is not specified by this product data.
What is the difference between the SD-15A-12 and the other SD-15A models?
Within the SD-15A group, SD-15A-5 is 15W, 5V, 3A; SD-15A-12 is 15W, 12V, 1.25A; and SD-15A-24 is 15W, 24V, 0.62A. All share the 9-18 input range, constant voltage operation, -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.
