Functions and Applications
The NVFP5 series inverter adopts sensorless vector control technology, with fast load response, large low-frequency torque, and strong overload capacity, which can achieve precise control of the equipment. It is equipped with RS485 communication protocol, and can be expanded with various communication functions and I/O ports to meet the complex control and system integration needs on site. It fully considers the harmonic interference of the industrial power grid, dust and oil pollution, and the product is equipped with a harmonic interference suppression circuit, which can effectively suppress harmonic interference. The modular structure design reduces the entry of dust and oil into the machine, and can meet the needs of complex on-site environments. It is widely used in petroleum and petrochemical, steel and metallurgy, chemical, non-ferrous, thermal power plants, new materials, papermaking and pharmaceuticals, building materials, food, water treatment, information electronics, rubber, rail transit, automobile manufacturing, shipbuilding and other industries.
