The Eighth-Brick series is a new high efficiency, open frame, isolated, 50 A product in an industry standard eighth-brick footprint and operates from a 36 Vdc to 75 Vdc supply. This new series elevates the power density threshold for high-end application design requirements where high output current at low voltages are required. The converter architecture takes advantage of open-frame construction to provide low mass and a low thermal impedance for a single board design. Additionally, a patent pending, full wave coupled inductor topology yields some of the highest full load efficiencies in the industry. All Eighth-Brick converters have, as standard features, remote ON/OFF capability, adjustable output voltage trim from 80% to 110% of nominal, over-current/under-voltage protection, and full international safety approval including EN60950-1 VDE and cUL60950.
