Frequently Asked Questions
Can I use the SD-50C-12 to derive 12V control power from a 36-72V industrial source?
Yes, this model converts a 36-72V input to a 12V constant-voltage output. It is rated for 4.2A, so it fits 12V control loads that stay within that current limit.
Is the SD-50C-12 suitable for 12V embedded electronics in higher-voltage industrial systems?
It is intended for equipment that needs regulated 12V output up to 4.2A while operating from a 36-72V source. That makes it relevant where the available system voltage is higher than the required 12V load voltage.
Can this converter power 12V automation accessories in equipment that uses a 36-72V bus?
It can fit 12V automation accessories, panel devices, or interface hardware that need constant voltage and draw no more than 4.2A. The input side is specified for 36-72V.
Is the SD-50C-12 appropriate for outdoor installations?
The operating temperature is specified as -10C to +60C, which defines the thermal range. The listed specs do not provide an IP rating, so outdoor or weather-exposed suitability is not stated here.
How do the SD-50C-5, SD-50C-12, and SD-50C-24 differ?
They share the same 36-72V input range but have different outputs. SD-50C-5 is 5V at 10A, SD-50C-12 is 12V at 4.2A, and SD-50C-24 is 24V at 2.1A.

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.
