Frequently Asked Questions
Can I use the SD-350D-5 for a 5V industrial controller or logic system fed from a 72-144V DC source?
Yes, this model provides a constant 5V output and is rated for 60A up to 300W. It is suited to 5V control, logic, or embedded loads that stay within the 60A and 300W limits.
Is the SD-350D-5 a good fit for 5V embedded computing or industrial SBC loads?
It can be used where the equipment requires a regulated 5V supply and the total load remains at or below 300W. With 60A available at 5V, it fits higher-current 5V DC applications better than lower-output models in the series.
Can the SD-350D-5 power 5V automation electronics in a higher-voltage DC system?
Yes, it converts a 72-144V input to a constant 5V output, which is useful when a higher-voltage DC bus has to feed low-voltage automation electronics. Its rated output is 300W at 60A, so the downstream 5V load must stay within those limits.
Can this converter be used in outdoor equipment cabinets or unsealed locations?
The operating temperature range is specified as -20°C to +60°C, but no IP rating is listed in the provided specs. That supports temperature planning, but it does not confirm suitability for direct outdoor exposure or wet locations.
What are the main differences between the SD-350D-5 and the other SD-350D versions?
The SD-350D-5 is rated at 300W with 5V output and 60A, while 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. The family shares the same general format, but each version is sized for a different output voltage and current requirement.

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.
