300W 24V Switching Supply for Industrial Use

This 300W switching power supply converts 90V to 264VAC input into a stable 24VDC output at 12.5A. It is built for industrial equipment, 3D printers, and LED lighting systems that require reliable enclosed power. The all-metal case provides full EMI shielding and 5G anti-vibration resistance.

85% Efficiency at Full Load

The unit delivers 85% typical efficiency while operating between 10°C and 60°C. A built-in long-life fan maintains thermal performance during continuous full-load operation. Comprehensive protection functions guard against common electrical faults in demanding environments.

Enclosed Chassis with 50mm Profile

The low-profile 1.97 inch (50mm) height fits tight cabinet spaces without special mounting hardware. Input terminals accept global mains voltages without selector switches. Installers must verify the 100W continuous rating matches the actual load to avoid thermal shutdown.

Questions about this item

What does the 300W rating mean when the supply is running inside a 3D printer or PC?

It means the unit can deliver up to 24 volts at 12.5 amps continuously, giving you 300 watts of DC power for the printer bed, hotend and electronics.

How does the 90 to 264 VAC input range affect where I can plug it in?

The wide range lets you connect it to 110 V or 220 V mains without changing a switch, and it will still start and regulate at the full 12.5 A output.

Will the 1.97 inch tall metal case fit in my printer's electronics bay?

The enclosed chassis is 50 mm high, so measure your bay clearance; the all-metal shell also acts as the mounting surface and EMI shield.
