Product Details

The MCOTS-B-270L-270-HT bus converter is a next-generation, board-mountable, isolated, fixed switching frequency DC-DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The MCOTS series provides an isolated 1 to 1 voltage from 230 V to 310 V intermediate bus with no regulation in a standard Half-brick module. MCOTS-B-270L-270-HT converter is ideal for creating the mid-bus voltage required to drive standard 270 V DC-DC isolated converters.
