The power supply is built into a powder coated metal enclosure designed for wall mounting and designed for continuous operation rated power. The connections for the AC input power, DC output copper bus bars, and controls terminals are located at the bottom of the wall mount enclosure. In addition to thorough attention to design and construction quality, the cooling system enables the power supply to work reliably with a long lifespan. The cooling air enters through air openings located on the wall-mount and a special designed Air Guiding System keeps the electronics isolated from the air flow. An Automatic Fan Speed Control adjusts the air flow to the required cooling, which reduces the wear of the cooling fans and reduced ambient noise.
