Frequently Asked Questions
Can I use this converter for a 24V PLC, relay, and sensor circuit in automation equipment?
Yes, it can fit a 24V constant-voltage load when the source is within 19-36VAC. The output is rated at up to 8.4A and 201.6W, so the total PLC, relay, and sensor demand needs to stay inside that range.
Will this work for a 24V HMI or industrial touchscreen system?
It can support a 24V HMI or touchscreen system that expects constant-voltage power. This model provides 24V output up to 8.4A, with 201.6W total available power.
Is this suitable for a 24V embedded controller or communications device?
It is appropriate for 24V embedded or communications hardware if the equipment uses a fixed 24V input and the load does not exceed 8.4A or 201.6W. The 19-36VAC input range also helps when the upstream source varies within that span.
Can this be used in a cold or hot indoor equipment enclosure?
The specified operating temperature range is -20°C to +60°C, so it is intended to operate across a fairly wide enclosure temperature range. Because no IP rating is listed, the safer fit is a protected indoor enclosure rather than direct outdoor exposure.
What are the differences between the SD-200B-48 and the other SD-200B versions?
The SD-200B variants listed here are SD-200B-12 at 170W, 5V, 34A; SD-200B-24 at 200.4W, 12V, 16.7A; SD-200B-48 at 201.6W, 24V, 8.4A; and SD-200B-5 at 201.6W, 48V, 4.2A. That means the selection is mainly about matching the required output voltage and current while staying within the same 19-36VAC input family.

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.
