Frequently Asked Questions
Can I use the SD-150B-12 to power a 12V automation panel from a 24V DC system?
Yes. This converter accepts 19-36V input and provides regulated 12V constant-voltage output. With 150W total power and 12.5A output current, it is suited to 12V automation and control loads on nominal 24V DC systems.
Is the SD-150B-12 a good fit for 12V industrial PCs, HMIs, or monitoring devices?
It can be a fit when the equipment requires a stable 12V supply and the load stays within 150W or 12.5A. The 19-36V input range matches many industrial DC systems in the 24V class. Its constant-voltage operation is intended for electronics that are specified for fixed 12V input power.
Can this converter support several 12V control devices from one 24V battery or DC bus?
It can support grouped 12V loads as long as the total demand remains within 150W and 12.5A. That makes it suitable for moderate-current 12V control, communication, and embedded devices on a 19-36V source. It offers more output headroom than the 102W, 8.5A SD-100 series units.
Is the SD-150B-12 suitable for indoor and outdoor installations?
No IP rating is listed, so this model is better suited to protected indoor enclosures rather than exposed outdoor locations. The operating temperature range is -10°C to +60°C. For outdoor service, an enclosure would need to provide the appropriate environmental protection.
How does the SD-150B-12 compare with other SD-150 models?
Within the SD-150 group, the SD-150B-12 is 150W at 12V and 12.5A, while the SD-150B-24 is 151.2W at 24V and 6.5A. The SD-150C-12 and SD-150D-12 are also 150W, 12V, 12.5A, and the SD-150C-24 and SD-150D-24 are 151.2W, 24V, 6.5A. The main difference across these 150W siblings is the output voltage and current combination by model.

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.
