ADQ500 Series


500 W Quarter Brick

The 500 W quarter-brick isolated DC-DC converters in the ADQ500 series offer regulated 12 VDC and up to 42 A output from an input range of 36 to 75 VDC with a typical full-load efficiency of 95.5%. Switching at 175 kHz, the parts are designed for 48 V supplies in computing, server, and communications equipment. Operating ambient temperature range is -40 to 85˚C. Standard protection features include input undervoltage, overvoltage lockout, output overvoltage, output overcurrent, and overtemperature conditions. The converters offer pre-bias start-up and allow paralleling with automatic droop method of current sharing. Choose from digital and analog interface options as well as open-frame and baseplate versions with 0.43 inch (11 mm) and 0.52 inch (13.3 mm) installed heights, respectively.
