Product features

◆ The perfect combination of measurement and control technology with synchronous switches has been achieved, controlling the movement speed of the switching switch, eliminating bouncing, improving lifespan, tracking and correcting the closing phase angle, and achieving millions of switches
Secondary cutting lifespan. Compared with existing intelligent power capacitors of the same kind, it has many advantages such as high reliability, low fault, low power consumption, and long service life.
◆ Closing without surge current, achieving zero crossing of capacitor voltage, current overcurrent cutting, synchronous switching completely avoiding switching overvoltage, no overvoltage breakdown, no arc pulling and reignition. In the most appropriate way
Compensation is provided, with complete control functions and high-end electric energy analyzer functions. It has complete functions and good performance, and can also be configured with various peripherals to meet different customer needs.
The product has complete measurement and protection functions, with special protections such as internal temperature of capacitors, harmonic content of the power grid, phase failure, and three-phase imbalance. The product can be used in a modular manner on multiple units, and when multiple units are used, they can be used independently
A reactive power automatic control system is formed by generating the main unit and the rest as the slave units. Individual faults occur and the slave unit automatically exits without affecting the operation of other machines. If the main unit fails, it automatically exits and a new main unit is generated,
Forming a new system requires a high level of intelligence. The individual capacitor displays the product's operating conditions and electrical circuit conditions, and the human-machine dialogue is concise and intuitive.
