Allen-Bradley 80558001177 IGBT Driver Circuit Board

The Allen-Bradley 80558001177 IGBT Driver Circuit Board provides isolated gate-drive control for IGBT power modules in industrial power electronics, serving as the switching interface between the system controller and high-power IGBTs to ensure reliable, high-speed gate switching with electrical isolation. Commonly installed in industrial variable frequency drives (VFDs), motor control systems, inverter assemblies, welding equipment, and power supplies where rapid, dependable gate transitions are required. Key specs include Part Number 80558001177, board number 14968 Rev C, and Reference 104277 4004; the board is an industrial PCB assembly designed for chassis or drive assembly mounting and provides gate-drive signal conditioning for IGBT modules. Typically used for OEM replacement, retrofit projects, and power electronics maintenance by maintenance teams and system integrators, it supports isolation between control and power stages (design dependent) and is compatible with industrial drives, inverters, motor controllers, and other high-power switching equipment.
