Frequently Asked Questions
Can I use the SD-100B-24 for 24V PLC I/O, sensors, or industrial control circuits from a 19-36V source?
Yes, it provides regulated 24V constant voltage output up to 4.2A with a 100.8W power rating. That makes it suitable for 24V automation and control loads when the input available is within 19-36V.
Is the SD-100B-24 a good fit for 24V industrial networking or communications equipment?
It can be used for 24V communications or control hardware that requires constant voltage and remains within 4.2A and 100.8W. The 19-36V input range can be useful in systems where the upstream DC source varies across that range.
Can the SD-100B-24 power a 24V embedded or automation subsystem inside equipment cabinets?
This model is intended for 24V constant voltage loads and can support subsystems up to 4.2A. Its 100.8W rating suits moderate-power embedded and automation assemblies rather than larger 24V loads.
Can the SD-100B-24 be used in outdoor cabinets or exposed locations?
The published specs include an operating temperature range of -15°C to +60°C, but they do not list an IP rating. Based on the stated data, it is better treated as a converter for protected indoor or enclosed use where that temperature range can be maintained.
What are the main differences between the SD-100B-24 and other SD-100 models?
In the SD-100 family, the 24V models SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 are each rated at 100.8W and 4.2A. The 12V versions SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12 are 102W and 8.5A, while the 5V versions SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 are 100W and 18A.

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.
