Frequently Asked Questions
Can I use the SD-500L-48 for 48V industrial networking or control equipment?
Yes, if the equipment requires constant 48V DC and the total load stays within 10.5A and 504W. The converter accepts a 19-72V input range and delivers regulated 48V output for higher-voltage DC systems.
Is the SD-500L-48 suitable for 48V embedded or edge-computing platforms?
It can be used where the platform is designed for a constant 48V input and the source is within the 19-72V range. With 504W output capacity, it fits higher-power 48V embedded and industrial electronics applications.
Can this converter power 48V automation devices from a variable DC source?
Yes, for automation loads that need regulated 48V DC up to 10.5A. The 4:1 wide input range supports source variation across 19-72V while maintaining constant-voltage output.
Can the SD-500L-48 be used in communications equipment with a 48V DC architecture?
It is a fit for communications or control equipment designed around 48V DC, as long as the total demand does not exceed 504W. The listed remote ON/OFF control and remote sense features are also relevant in supervised equipment systems.
How does the SD-500L-48 compare with the other SD-500L models?
The SD-500L-48 is rated for 504W at 48V and 10.5A. The SD-500L-12 is 480W at 12V and 40A, and the SD-500L-24 is 504W at 24V and 21A. All three share the 19-72V input range, 215.0 × 115.0 × 50.0 mm dimensions, 1.15 kg weight, and -20°C to +60°C operating range.
Is the SD-500L-48 rated for outdoor environments?
The provided specs list an operating temperature range of -20°C to +60°C. They do not list an IP rating, so the supplied data does not confirm outdoor or water-exposed use without an additional protective enclosure.

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.
