Overview
The Mitsubishi CM400HA-24H is a single IGBTMODâ„¢ power module designed for demanding industrial switching applications. This 1200V, 400A module combines robust construction with low conduction losses, making it ideal for motion control, UPS systems, welding power supplies, and laser power systems. The isolated baseplate and H-series architecture provide reliable thermal management and design flexibility for custom power converter topologies.
