Gate Unit Power Supply ABB 3BHB004661R0101

Description

The ABB 3BHB004661R0101, also known as KUC711AE101, is a gate power supply unit engineered to deliver galvanic isolation and fast switching performance for insulated-gate bipolar transistors (IGBTs) in medium-voltage drive systems. It is a critical component in ABB’s ACS800/ACS1000 drive platforms, supporting fiber-optic triggering and high-voltage isolation between control electronics and power semiconductors. The module is built to operate in harsh industrial environments, offering 5 kV isolation voltage and ≤50 ns propagation delay, ensuring accurate and synchronized gate firing. Its rugged design and ABB’s proprietary Fiber-Optic Triggering (FOT) technology make it ideal for high-speed, high-reliability applications.
