Frequently Asked Questions
Can I use the SD-25B-24 to power a small 24V PLC or control module?
It can fit small 24V control electronics that stay within the 24V, 1.1A, and 26.4W output rating. That makes it more appropriate for low-power PLC logic, compact controllers, or light automation loads than for larger 24V devices.
Is the SD-25B-24 suitable for 24V sensors, relays, and interface devices in an automation panel?
Yes, it is intended for constant-voltage 24V output and can support loads up to 1.1A with 26.4W available. It is a better fit for smaller 24V interface devices and relay or sensor circuits than for higher-current 24V equipment.
Can this converter be used in a vehicle or mobile equipment system with a 19-36V source?
It is designed for applications where the input stays within the 19-36V range and the load needs 24V constant voltage output. With 26.4W maximum output power, it suits lower-power embedded or control loads rather than larger 24V accessories.
How does the SD-25B-24 compare with the other SD-25B models?
Within the SD-25B group, the output options are SD-25B-5 at 25W, 5V, 5A; SD-25B-12 at 25.2W, 12V, 2.1A; and SD-25B-24 at 26.4W, 24V, 1.1A. All use the same 19-36V input range and share the same compact series class.
Is the SD-25B-24 suitable for outdoor or harsh-environment use?
No IP rating is listed in the provided specs, so this model should not be treated as an outdoor or washdown unit based on the available data. The stated operating temperature range is -10°C to +60°C, which supports controlled indoor equipment environments within that temperature window.

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.
