Product Details

The MCOTS-B-900-28-FT 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 step down voltage from 900 V to 28 V intermediate bus with no regulation in a standard full-brick module. MCOTS-B-900-28-FT converter is ideal for creating the mid-bus voltage required to drive standard 28 V DC-DC isolated converters.
