  5. YASKAWA AC Drive - Varispeed G7

General Purpose Inverter with Advance 3 Level Control Drive

The Varispeed G7 is the first general-purpose inverter in the world to feature the 3-level control method for 400V with PWM. This control technique solves the problem of micro surges, and makes it possible to use the Varispeed G7 on existing motors.It protects motor winding and bearing and lengthen motor live.
