Features

1. High-speed digital signal processor core.

2. Chinese and English interface optional, optional manual and automatic mode
3. Reactive power and power factor are used as composite control objects, effectively avoiding over or under compensation of
reactive power, and no switching oscillation occurs at small loads
4. Analysis system 3 ~ 21th harmonic content, voltage harmonic total distortion rate (TH Du%), current harmonic total distortion
rate (TH Di%)

5. Adopt adaptive frequency algorithm, strong
anti-interference ability, adapt to thousands of complicated site conditions
6. According to the capacity setting of each
compensation branch, the combination of "cyclic switching" and "encoding optimized switching" improves the compensation accuracy and extends the service life of the capacitor bank.
7. International Modbus communication protocol.
