Product Overview

The EP4 200A1200V/ZGAD-561 is a pre-assembled power unit combining a 200A 1200V half-bridge IGBT module in EP4 package and the matched ABB ZGAD-561 isolated gate driver circuit board, engineered exclusively for medium and high-voltage industrial variable frequency drive systems. This integrated assembly delivers fully isolated gate signal amplification, real-time power device health monitoring, and fast fault protection for high-power inverter main power loops.
