Controllers
Reactive Power Compensation Controller
The Reactive Power Compensation Controller is a fully digital device with AC sampling and a large-screen LCD Chinese interface. It displays real-time power factor, voltage, current, active power, reactive power, voltage and current THD, frequency, capacitor output and switching status, and alarms for L1, L2, and L3.
Overview
The controller uses reactive power as the sampling quantity and includes harmonic measurement and protection. Capacitor control schemes support three-phase compensation, split-phase compensation, and combined compensation, selectable via menu. Switching control programs support equal-capacity, coding, and fuzzy control modes, with manual and automatic operation. An RS-485 MODBUS fieldbus interface allows connection to intelligent switchgear systems. Optional factory power distribution monitoring software can be connected to the controller communication port to view real-time data, historical load curves, and reports on a computer. Data can be uploaded to a cloud platform for remote monitoring.
