NVF2 series inverter is a high performance open loop vector inverter, it has high starting torque, strong overload capacity, flexible and convenient operation, positive and reverse PID control and other features. This series of inverters are divided into heavy load type (constant torque type) and light load type (fan-pump type), which have the features of strong load adaptability, stable and reliable operation, and automatic energy saving operation. Products are widely used in paper making, textile, water supply, municipal, food, cement, chemical, printing, metallurgy, mining, plastic machinery and other electrical transmission and automation control fields.
The NVF2 series variable frequency drives are high‑performance open‑loop vector drives developed for a wide range of industrial applications such as paper making, textile, water supply, and metal processing. Two types are offered: heavy‑load (constant torque) and light‑load (fan/pump) models, supporting single‑phase and three‑phase input voltages.
The manual details environmental limits, protection features, technical parameters, terminal assignments, mechanical dimensions, and ordering information, helping users select the correct model and install the drive safely. This manual is written in Chinese.
