CM400DY-66H Mitsubishi - IGBT Module
CM400DY-66H Description
The CM400DY-66H from Mitsubishi Electric is an IGBT module with a 3300 V / 400 A rating. Inside, it has two switches in a half-bridge (2-in-1) arrangement. Engineers use it mainly in the inverter section of motor drives, as well as in UPS, welding and power-conversion equipment. Production of many older modules has ended, but we keep sourcing them for repair and maintenance customers.
USComponent is a BBB A+ accredited distributor that specializes in power modules and industrial components, new and legacy. Ask us for a quote on the CM400DY-66H; we ship worldwide. Please verify the ratings and package against the manufacturer's datasheet first.
