Frequently Asked Questions
Can I use the SD-350B-48 for 48V telecom or networking equipment from a 19-36V DC input?
Yes, this model converts a 19-36V input to a constant 48V output. Its 350.4W rating and 7.3A output make it suitable for 48V equipment that needs regulated DC power in telecom, networking, or industrial systems.
Is the SD-350B-48 appropriate for 48V industrial automation devices or controllers?
It can be, provided the load expects a constant 48V supply and stays within 7.3A. The 350.4W output gives it more capacity than lower-power 48V converters in the family for heavier automation loads.
Can this converter support a 48V embedded or communications subsystem in a vehicle or cabinet?
Yes, if the available source is within 19V to 36V and the downstream equipment requires regulated 48V DC. The model is designed as a constant-voltage converter and includes 1.5~2KVAC isolation by models, which is relevant in many industrial and embedded power architectures.
Can the SD-350B-48 be used outdoors or in wide-temperature locations?
The published operating temperature range is -20°C to +60°C, so it is specified for that temperature span. No IP rating appears in the provided specs, so outdoor suitability is not confirmed by the listed information.
How does the SD-350B-48 compare to the other SD-350B voltage options?
In the same SD-350B series, the 5V version is 285W at 57A, the 12V version is 330W at 27.5A, the 24V version is 350.4W at 14.6A, and this 48V version is 350.4W at 7.3A. The main differences are the output voltage and the current available at that voltage.

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.
