capacitor bank reactive power controller/12 levels/6 levels/8 levels/JKW5C

Product catalog summary

General Overview
The JKW series reactive power auto-compensation controllers are designed for three-phase compensation in low voltage distribution systems. They automatically adjust capacitor compensating devices to achieve a predetermined power factor, enhancing transformer efficiency, reducing line loss, and improving voltage supply.

Main Parameters and Conditions

High precision in reactive power compensation and power factor measurement.
Initial phase presetting with software-adjustable polarity.
Two control modes: power factor control and reactive power control.
User-friendly interface with digital control parameters.
Automatic and manual operation modes.
Protection against over-voltage, under-voltage, and memory protection for power failures.
Low current signal input impedance (≤0.01Ω).

Main Structural Features
Details on structural features are not explicitly provided in the document.
