DC-DC Converter

Product Details

The InQor half-brick converter series is composed of nextgeneration, board-mountable, isolated (REINFORCED INSULATION), 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.
