| Corporate: www.cdtechno.com Corporate: www.cdtechno.com Product: www.cdpoweronline.com VKQ100MS05 100 Watt, 5.0Vout, Quarter Brick DC/DC Converter FEATURES No Heatsink Required 36 - 75V Input Range No External Components Required Small Size: 1.5" x 2.3" x .50" Safety per UL/CUL 60950, High Efficiency: >86% EN 60950, Operational Fixed Frequency Operation Insulation Meets TNV-SELV 480kHz Isolation Requirements Primary Remote On/Off Adjustable Output Voltage APPLICATIONS Brick Wall Current Limiting Distributed Power Architectures On Board Input Differential Telecommunications Filter Battery Powered Systems No Minimum Load Requirement Workstations Remote Sense The VKQ100MS05 DC/DC converter presents an economical and practical solution for distributed power system architectures which require high power density and efficiency while maintaining system modularity and upgradeability. With the ability to operate over a wide input voltage range of 36 to 75 Vdc, this module is ideal for telecommunications and battery backup applications where input flexibility must be combined with output voltage regulation. In addition, the output is fully isolated from the input, allowing for a variety of polarity and grounding configurations. Innovative circuit design using surface mount components results in a compact, efficient and reliable solution to DC/DC conversion needs. Internal power dissipation is minimized by the VKQ100MS05's high efficiency and is aided by a metal baseplate to which all heat dissipative elements are coupled. The control circuitry of the VKQ100MS05 has been designed to provide overvoltage protection as well as current limiting for continuous shortcircuit protection.
