Frequently Asked Questions
Can I use the SD-350D-48 to power a 48V telecom or network appliance from a 72-144V DC source?
Yes, it is a constant-voltage DC-DC converter with a 48V output rated at 7.3A and 350.4W. That makes it a fit for equipment that specifically requires 48V DC and stays within the 7.3A output limit.
Is the SD-350D-48 suitable for industrial control equipment that runs on 48V DC?
It can be used for industrial control loads that require a regulated 48V output and draw no more than 350.4W or 7.3A. The unit is designed for constant-voltage output and accepts a 72-144V input range.
Can this converter support embedded or automation systems with a 48V DC bus?
It is appropriate for embedded or automation systems that need 48V DC and fit within the converter's 350.4W capacity. Its 2:1 wide input range and 1.5~2KVAC isolation by models are useful in higher-voltage DC systems.
Is the SD-350D-48 suitable for outdoor or harsh-environment use?
The provided specs list an operating temperature range of -20°C to +60°C, but they do not list an IP rating. That means the temperature range is specified, while exposed outdoor or washdown suitability is not established by the listed specs.
How does the SD-350D-48 compare with the other SD-350D models?
Within the SD-350D group, the SD-350D-5 is 300W at 5V and 60A, the SD-350D-12 is 350.4W at 12V and 29.2A, the SD-350D-24 is 350.4W at 24V and 14.6A, and the SD-350D-48 is 350.4W at 48V and 7.3A. All are DC-DC converters in the same family, but the output voltage and current ratings differ by model.

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.
