DRC series intelligent reactive power compensation controller

DRC series intelligent reactive power compensation controller is a new generation of control device developed with the most advanced technology.
1. Using 32-bit ARM chip, real-time data collection, power statistics, historical data storage, fault alarm, power grid harmonic analysis and other functions are realized.
2. Adhering to the human-oriented design concept, the man-machine interface is friendly, and the operation is convenient.
3. Modular assembly, streamlined appearance design. The display interface adopts LCD Chinese display, both pictures and texts, and the interface is rich in content.
4. Three-phase voltage and three-phase current sampling, real-time display of A, B, C three-phase voltage, current, power factor, active power, reactive power, total power factor, voltage total harmonic distortion rate, current total harmonic Distortion rate, frequency and other information.
5. It can realize fast dynamic reactive power compensation control, and the capacity of each channel can be set separately to ensure reliable input and no shock when the load is low.
6. In order to ensure the safety of parameter setting, this machine has a lock function. The parameter setting can only be carried out after the correct password is entered and the programming lock is unlocked.
7. It has multiple protection functions such as undervoltage, overvoltage, harmonic overrun, and current blocking.
8. Powerful data collection and processing functions can be used for data transmission, statistics and storage.
