Automatic Reactive Power Compensation Controller
JKW5C
The JKW series reactive power automatic compensation controller is suitable for the automatic adjustment of capacitor compensation devices in low-voltage power distribution systems (hereinafter referred to as the controller), so that the power factor reaches the user's predetermined state, improves the utilization efficiency of power transformers, reduces line losses, improves the quality of power supply voltage, and thus improves economic and social benefits.
1. High power factor measurement accuracy and wide display range
2. Automatic current polarity identification
3. Two control modes: power factor (easy-to-use) and reactive power (high compensation accuracy)
4. All control parameters are fully digitally adjustable, intuitive and easy to use
5. Two operating modes: automatic and manual
6. Undervoltage and overvoltage protection functions
7. Low current signal input impedance ≤0.01Ω
Power Factor Control Mode Features: This controller is factory-set to power factor control mode. Except for potential circuit modifications, other parameters are pre-set in the most efficient way. Users only need to connect the wires correctly for normal operation.
Reactive Power Control Mode Features: Precisely controls capacitor bank switching, avoiding switching oscillations. Suitable for all operating environments, especially light loads with large capacitors.
