Product Details

The RailQor® half-brick converter series is composed of nextgeneration, board-mountable, isolated (REINFORCED), fixed switching frequency dc-dc converters that use synchronous rectification to achieve extremely high power conversion efficiency. Each module is supplied completely encased to provide protection from the harsh environments seen in many industrial and transportation applications.
