High Quality Power Supply 12V 33A with Fan S-400-12

The Power Supply 12V 33A (model S-400-12) is a 400 W enclosed switching power supply that converts mains AC into a steady 12 V DC at up to 33 A. A built-in cooling fan keeps it cool under heavy load, and screw terminals make wiring simple, so it is well suited to LED strips, CCTV systems, 3D printers, CNC machines and other 12 V equipment.
