Product Introduction

The JKWD5 Automatic Reactive Power Compensation Controller is engineered specifically for low-voltage (400V) distribution networks. By automatically regulating reactive power, JKWD5 Automatic Reactive Power Compensation Controller maintains the grid's power factor within optimal target ranges. This significantly enhances transformer utilization efficiency, reduces line losses, and stabilizes voltage supply quality.

Furthermore,JKWD5 Automatic Reactive Power Compensation Controller helps facility operators avoid costly utility power factor penalties, maximizing both operational efficiency and economic returns.

Product Features

Dual Operation Modes: Supports both Power Factor Control and Reactive Power Control for maximum application flexibility.

Anti-Hunting Protection: Features advanced switching oscillation blocking in Power Factor mode to prevent rapid, repetitive capacitor cycling and extend equipment lifespan.

Automatic Polarity Detection: Automatically detects current signal polarity with exceptional precision and reliability, eliminating wiring errors during installation.

Intuitive User Interface: Designed with a user-friendly interface for streamlined operation and straightforward navigation.

Harmonic Monitoring & Protection: Equipped with real-time harmonic measurement capabilities and protective trip features to safeguard capacitor banks.

Fully Digital Parameters: All control thresholds and parameters are fully adjustable digitally for precise system tuning.

Dual Control Modes (Manual/Auto): Offers both manual and automatic operation modes to simplify installation, testing, and system commissioning.

Overvoltage Protection: Monitors system voltage and automatically disconnects capacitor banks during overvoltage events to prevent component damage.

Non-Volatile Memory Storage: Retains all programmed parameters permanently, ensuring settings are unaffected by power outages or system shutdowns.

Control parameter presetting:
