Product Applications

Water treatment and environmental protection plants: Primarily used for small and medium-sized industrial water pumps, blowers, and constant pressure water supply systems. In low overload (LO) mode, it can perfectly drive 5.5 kW fan and pump loads, achieving variable frequency energy saving and emission reduction.

Packaging and printing machinery plants: Used for material feeding and winding control in bag making machines, case packing machines, label printing machines, etc. The G120's powerful vector control capability ensures constant tension of paper and plastic film at different production speeds.

Automotive manufacturing and machine tool processing plants: Responsible for smooth motor control in automotive assembly lines and machine tool auxiliary axes (such as cutting fluid pumps, chip conveyors, and small conveyor tracks). Its excellent anti-interference and low failure rate effectively avoid huge losses caused by unexpected production line downtime.

Plastics and rubber processing plants: Widely used for power control of small injection molding machines, extruder feeding devices, and mixing machines.

Lifting and material handling plants: Used for smooth speed regulation of small overhead cranes, elevators, or trolleys, ensuring smooth material movement and preventing swaying.
