Frequently Asked Questions
Can I use the SD-500H-24 for 24V PLC, control panel, or automation equipment on a 72-144V DC bus?
Yes, it provides a constant 24V output rated at 21A and 504W. That suits 24V industrial control or automation equipment as long as the connected load remains within the 21A output rating.
Is the SD-500H-24 suitable for 24V embedded or communications equipment in a higher-voltage DC system?
It can be used when the equipment requires regulated 24V DC and the load does not exceed 504W. The converter accepts a 72-144V input and uses a 4:1 wide input range, which fits broader-input DC systems.
Can this model support 24V automation applications that need auxiliary power and remote control features?
Yes, the listed features include a 12V/0.25A auxiliary output, built-in remote ON/OFF control, and remote sense. Those features can help in 24V automation systems where the main load is powered from the 504W, 21A output.
Is the SD-500H-24 appropriate for exposed outdoor use?
The provided specs give an operating temperature range of -20°C to +60°C, but they do not provide an IP rating. That means temperature capability is stated, while exposed outdoor suitability is not confirmed by the listed data.
What are the differences between the SD-500H-24 and the other SD-500H models?
The SD-500H-12 is rated at 480W with 12V output and 40A, the SD-500H-24 is 504W at 24V and 21A, and the SD-500H-48 is 504W at 48V and 10.5A. The series shares the same physical size and feature set, but each version is matched to a different output voltage and current level.

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.
