Cosel GHA700F Power Supplies
Cosel GHA700F Power Supplies are 700W high-density base plate-cooled AC/DC power supplies with low leakage current. These power supplies deliver power based on the robust platform with optimized thermal conduction. The GHA700F power supplies feature a power density of 33.8W/in3, a universal input voltage range of 85VAC to 264VAC, and an efficiency of up to 96%. These power supplies are available in four output voltages of 24VDC, 30VDC, 48VDC, and 56VDC, to power an extensive range of systems-bus voltages. The GHA700F power supplies offer inrush current limitation, over-voltage protection, and over-current protection with automatic recovery when the fault condition is removed. The GHA700F measures 76.2mm x 38.1mm x 127mm (W x H x D) and weighs 570g maximum. These power supplies are used in medical and ITE applications.Features
