BusQor DC-DC Bus Converters
    Open-frame, single board construction for higher reliability
BusQor Series Bus Converters The BusQor® bus converter are the next-generation, board-mountable, isolated, fixed switching frequency DC-DC converters that use synchronous rectification to achieve extremely high conversion efficiency.  The BusQor® bus converters are available in Un-regulated, Semi-regulated, Fully-regulated and High Input Voltage models.  The SynQor bus converters are ideal for creating the mid-bus voltage required to drive standard point-of-load (non-isolated) DC-DC isolated converters.
