Fuji Electric Holdings Co., Ltd., announces today that its core operating company, Fuji Electric Systems Co., Ltd., has released the high-performance FRENIC-VG series of vector control※1 invertors that achieve the industry’s highest level of control performance.
Calls are growing for improved productivity of equipment that uses invertors, such as machinery at production plants and factories, and conveyor cranes at seaports. Accordingly, invertors that feature high performance and multi-functionality are increasingly in demand. In response, Fuji Electric Systems is releasing the FRENIC-VG series of inverters that feature a speed response of 600 hertz, six times the level of the company’s previous models. The series achieves the high precision and detailed control required by production plants and equipment to control response speed during vector control, thereby further raising production efficiency.
Fuji Electric Systems is offering a wide range of models in the high-performance FRENIC-VG series of vector control※1 invertors to contribute to improving the productivity of customers’ production facilities and equipment.
