TKD12ZED Datasheet | Power-One

TKD SERIES - 50 WATT, 3/4 BRICK DESCRIPTION The TKD series of dual-output DC/DC converters provides high power and full isolation in a low cost, single-board design package. The TKD series provides highly reliable, onboard conversion of tele and data input voltages to isolated low output voltages without the need for a heatsink. The TKD series is ideally suited for Distributed Power Architectures (DPA), telemunications equipment, LAN/WAN, and data processing applications.
