DQC3000B Intelligent Dynamic Reactive Power Compensation Controller is a new type of power quality monitoring terminal developed by Orient Borvo (Beijing) Technology Co., Ltd. It is used for distribution systems with frequent load changes and harmonics below 1000V. It features dynamic compensation control, real-time harmonic analysis, and power parameter measurement and display.
The DQC3000B Intelligent Dynamic Reactive Power Compensation Controller, developed by Dongfang Bow (Beijing) Technology Co., Ltd., is designed for distribution systems with voltages up to 1000 V that experience frequent load changes and harmonic distortion. It uses a TI DSP processor to provide fast reactive power compensation (response ≤10 ms) and real‑time harmonic analysis (2‑31 orders).
The manual covers the controller’s main functions, hardware specifications, wiring diagrams, communication interfaces (RS232, RS485, CAN‑BUS), data logging capabilities, and safety precautions. Installation instructions, terminal assignments, and configuration guidelines are provided for both star‑feed‑forward and star‑feedback wiring modes. This manual is written in Chinese.
