Varispeed G7

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.

Features

• The First Product in the world which works on 3-Level Control Method
• Accurate Torque control which protects the machine from sudden load fluctuations.
• High speed search function save the recovery time during momentary Power loss.
• Low Surge voltage, Low Electrical noise,Low Acoustic noise and Leakage current is greatly reduced
• Energy Saving control performance reduces the operational cost
• LCD keypad display: 5 lines x 16 characters, backlit, 7 languages, copy function
• Support Global Field bus Networks
• Certified under UL/cUL and CE Marking as standard
