ABB UFC762AE101 3BHE006412R0101 – Factory-Tested Inverter Circuit Board for Motor Drives

Description

Application Scenarios

At a steel rolling mill in Brazil,frequent inverter failures were causing unplanned downtime during hot rolling operations.The root cause was traced to degraded gate driver signals leading to IGBT shoot-through and module burnout.Maintenance engineers replaced the faulty control boards with the ABB UFC762AE101 3BHE006412R0101 Inverter Circuit Board,which restored precise timing and isolation in the drive’s PWM signals.Since the upgrade,the drives have operated without failure for over 18 months,even under high-temperature and high-vibration conditions.The board’s robust optocouplers and reinforced power regulation proved essential in stabilizing motor control during peak load cycles.
