RailQor® PCB DC-DC Converters

DC-DC isolated converter modules for the rail industry.

Supplier: SynQor®

Technology type: PCB DC/DC Power Supplies

The RailQor® converter series is composed of next-generation, board-mountable, isolated, fixed switching frequency DC-DC converters that use synchronous rectification to achieve extremely high power conversion efficiency, even at low output power levels.

The quarter-brick 25W - 50W mega-series has power dissipation so low that no heatsink is necessary to operate at 85°C in an enclosed environment without airflow. Each module is supplied completely encased to provide protection from the harsh environments seen in many industrial and transportation applications.
