1MBI800U4B-120 Fuji Electric - IGBT Module

1MBI800U4B-120 Description

1MBI800U4B-120 is a 1200 V, 800 A IGBT module made by Fuji Electric. The module contains a single switch with its freewheeling diode (1-in-1). Modules like this do the heavy switching in motor drives, UPS systems, induction heaters and renewable-energy inverters. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.
