Capacitor controller

The QEI Capacitor Controller is a modern reactive power compensation solution, utilizing an intelligent system to maintain a stable and optimal power factor (cosφ) for the electrical system.

The product is designed to automatically switch capacitor banks based on real-time load demand, thereby reducing power losses, avoiding reactive power penalties, and improving operational efficiency for businesses.

Key Features:

• Intelligent and precise control. Utilizing the QEI capacitor controller, the system automatically adjusts capacitor banks based on cosφ, kW, kVAr, current, voltage and temperature. It responds rapidly to load fluctuations.
• Flexible programming. Settings based on time and operating schedules. Multiple customizable control modes. Suitable for complex electrical systems.
• Operational cost optimization. Reduces power losses. Avoids reactive power penalties. Enhances electricity utilization efficiency.
• Durable design – easy to operate. The cabinet is robustly manufactured to meet technical standards. High-quality components ensure a long service life. Easy to maintain and expand.
