myVolts 12V 33A 400W AT Power Supply

Industrial AT power supply

The myVolts 12V 33A 400W AT power supply converts AC 100-240V input to a regulated 12V DC output at 33A. It is built for industrial automation, LED displays, CCTV systems, radio equipment, computer projects, LED strip lighting and 3D printers. A metal enclosed body aids heat dissipation and the unit includes a cooling fan rated for -20 to 60 Celsius operating temperatures.

Sustained load protection

Under continuous operation the supply relies on short-circuit, overload, over-voltage, over-current, overheat, leakage and over-cooling protection circuits. The fan-cooled metal enclosure maintains thermal stability across the full -20 to 60 Celsius range. Protection features engage automatically to preserve the unit and connected equipment during prolonged high-current draw.

AC input voltage selection

The unit accepts 100-240V AC at 50/60Hz but requires manual selection between 110V and 220V via a physical switch before powering on. Incorrect switch position can damage the supply. Output connections use screw terminals for secure wiring. No other input standards or automatic ranging are supported.
