Product overview
The Yaskawa GA50C4018EBA is a compact industrial variable-frequency drive for controlling the speed and torque of induction, permanent-magnet and synchronous-reluctance motors.
This version supports motors up to 5.5 kW in heavy-duty operation or 7.5 kW in normal-duty operation. It incorporates an EMC filter, braking transistor, Safe Torque Off and multiple communication options.
