Industrial 240W 12V Power Supply

The ALRS12V20AT delivers 240 watts at 12 volts with a 20 amp output for 3D printers, computing equipment and LED installations. Its enclosed 41mm low-profile chassis fits tight industrial cabinets. The unit ships new and ready for continuous duty.

Selectable AC Input and Surge Tolerance

A slide switch selects 110V or 220V nominal input across a 90V to 264VAC range. The supply withstands a 300VAC surge for five seconds without damage. Efficiency exceeds 85 percent, reducing heat in enclosed racks.

Fan-Cooled Installation and Vibration Limits

A built-in long-life fan maintains full-load operation from 10°C to 60°C ambient. The 5G anti-vibration rating suits stationary machinery but not mobile or high-shock environments. Buyers needing redundant or hot-swap modules should specify a different architecture.
