Automatic Reactive Power Compensation Controller
JKWD5
The JKW series reactive power automatic compensation controller is suitable for automatic adjustment of capacitor compensation devices in low-voltage distribution systems (hereinafter referred to as the controller). It ensures the power factor reaches the user's desired state, improves transformer utilization, reduces line losses, and improves the voltage level of the power supply, thereby enhancing economic and social benefits.
1. Calculates switching capacitor capacity based on reactive power, resulting in high compensation accuracy.
2. High power factor measurement accuracy and a wide display range.
3. Initial phase preset (software adjustment of the same-name terminal or current signal polarity).
4. Two control modes: power factor and reactive power.
5. User-friendly human-machine interface for easy operation.
6. Fully digitally adjustable control parameters for intuitive and easy use.
7. Automatic and manual operation modes.
8. Overvoltage and undervoltage protection.
9. Power-off protection to prevent data loss.
10. Low current signal input impedance ≤ 0.01Ω.
Operating Conditions:
1. Altitude not exceeding 2,500 meters.
