Product description
Parameters

  BQ800 series inverter is a high-performance vector inverter independently developed by our company, which can realize the control and regulation of asynchronous motor. BQ800 series uses high-performance vector control technology, low speed, high torque output. It has good functional characteristics, strong overload capacity, supports multiple function cards, and supports embedded installation and wall-mounted installation in terms of installation method. It has powerful functions and stable performance.
