Frequently Asked Questions
Can I use the SD-100A-5 for 5V embedded controllers or industrial computing hardware?
Yes, it provides a constant 5V output and can deliver up to 18A. With a 100W rating and a listed 9-18V input range, it fits higher-current 5V DC applications within that power limit.
Is the SD-100A-5 suitable for powering 5V logic or communications equipment from a low-voltage DC bus?
It is designed for 5V constant voltage output from an input source in the listed 9-18V range. The 18A output capacity supports 5V loads that need relatively high current within the 100W rating.
Can this converter be used for 5V automation electronics in battery-powered systems?
Yes, if the source remains within the specified 9-18V range and the load needs regulated 5V DC. The converter is rated for up to 100W total output power and 18A output current.
Is the SD-100A-5 intended for outdoor environments or only protected enclosures?
The operating temperature range is listed as -15°C to +60°C. No IP rating is provided, so the specs do not identify it as an outdoor-rated or water-resistant model.
How does the SD-100A-5 compare with the other SD-100A models?
Within the SD-100A family, the SD-100A-5 is 100W at 5V and 18A, the SD-100A-12 is 102W at 12V and 8.5A, and the SD-100A-24 is 100.8W at 24V and 4.2A. They are all around the same power class, with different output voltages and current levels.

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.
