1. It adopts intelligent controller control, complete functions, reliable performance, automatic compensation method; can increase the power factor to above 0.9;
2. Real-time display of power factor of the grid, display range: lag (0.00-+0.99), lead (0.00- -0.99);
3. It has multiple comprehensive protection functions such as over-voltage, over-harmonic, over-compensation, system failure, phase loss, overload, etc.;
4. Memorizes the parameters that have been set, the parameters will not be lost after the system is powered off, and the power grid is restored After it is normal, it will automatically enter the running state without personnel on duty;

Ordering instructions
1. The capacity of on-site compensation should not be too large to avoid damage to the motor. According to the capacity, generally no more than 30% of the motor power, and the compensation reactive current is less than 90% of the motor no-load current;
2. Frequency conversion speed regulation, thyristor Motors with voltage regulation and frequent forward and reverse rotation, and reverse connection braking cannot use this product;
3. The on-site compensation line is directly connected to the motors D1, D2, and D3.
