Why Choose ZHIMING's Reactive Power Auto-Compensation Capacitor Controller?
Intelligent Real-time Grid Monitoring
The reactive power auto-compensation capacitor controller continuously samples real-time voltage, current and power factor data of low-voltage three-phase grid. Based on collected operational parameters, this reactive power auto-compensation capacitor controller calculates required compensation capacity accurately to match varying load changes dynamically.
Automatic Capacitor Switching Control
Instead of manual on-off operation, the reactive power auto-compensation capacitor controller outputs automatic switching signals to accessorily matched compensation capacitors. It realizes graded input or cut of capacitance to lock system power factor within preset target range efficiently.
Multiple Built-in Safety Protection Functions
Equipped with overvoltage, undervoltage and overcurrent protection logic inside, the reactive power auto-compensation capacitor controller cuts off capacitor loops timely under abnormal grid conditions. This design avoids capacitor breakdown and extends the whole service life of matched compensation equipment.
Wide Compatibility With Various Capacitors
The reactive power auto-compensation capacitor controller supports collocation with standard dry-type, anti-harmonic low-voltage three-phase power capacitors. It fits most conventional reactive compensation cabinets used in industrial plants, commercial buildings and distribution stations.
Cost-saving & Long-term Economic Benefit
By stabilizing power factor and lowering reactive power waste, the reactive power auto-compensation capacitor controller helps users eliminate extra penalty charges from power supply bureau. Less circuit power loss also reduces monthly power consumption for long-running production workshops.
