What Is an APFC Panel and Why Is It Important for Electrical Efficiency?
An APFC Panel, or Automatic Power Factor Correction Panel, is an electrical control system designed to automatically improve the power factor of an electrical installation by switching capacitor stages according to changing load conditions. It helps compensate for reactive power, reduce avoidable electrical losses, improve system efficiency, and support stable operation of connected equipment. APFC systems are particularly relevant for facilities with motors, transformers, HVAC equipment, and other inductive loads where maintaining an improved power factor can contribute to better electrical performance and reduced demand-related costs.
Types of APFC Panel
As APFC Panel Manufacturers, Suppliers, Dealers, Traders, Wholesalers and Exporters in Pune, we offer reliable APFC panels for efficient and automatic power factor correction across various electrical applications.
- Contactor-Switched (Relay-Based) APFC Panel This APFC Panel uses electromechanical contactors controlled by a microprocessor-based APFC relay to switch capacitor steps according to reactive power demand. It offers a cost-effective and dependable solution for electrical systems with stable or gradually changing loads.
- Thyristor-Switched (Solid-State / Real-Time) APFC Panel This panel uses solid-state thyristor switches for rapid capacitor-stage operation without mechanical contactor movement. It is ideal for fast-changing loads such as cranes, welding equipment, and machinery with frequent load fluctuations.
- Hybrid APFC Panel A Hybrid APFC Panel combines fixed or contactor-switched capacitor stages for steady base loads with thyristor-switched stages for rapidly varying loads. This configuration provides economical power factor correction while maintaining fast response to sudden changes in reactive power demand.
- Detuned APFC Panel A Detuned APFC Panel incorporates series reactors with capacitor banks to reduce the risk of harmonic resonance and protect capacitors in harmonic-rich electrical networks. It is particularly suitable for installations using VFDs, computers, UPS systems, and other non-linear electrical loads.
- LT (Low Tension) APFC Panel An LT APFC Panel is designed for low-voltage electrical distribution systems, commonly operating at 415V, to automatically compensate reactive power. It is widely suitable for commercial buildings, offices, manufacturing facilities, and small-to-medium industrial installations.
- HT (High Tension) APFC Panel An HT APFC Panel is engineered for high-voltage systems such as 11kV or 33kV installations, supporting reactive power compensation on the primary side of transformers. It is mainly used in heavy industrial facilities where high electrical loads require centralized and effective power factor management.
Our Power Factor Correction Panels include APFC Control Panels, Electric APFC Panels, LV APFC Panels, Three-Phase APFC Panels, and APFC Capacitor Panels, designed to improve power factor, compensate reactive power, and support efficient electrical operation.

FAQ’s
An APFC panel automatically adds or removes capacitor stages to improve the facility’s power factor according to the load. By reducing excessive reactive power demand and improving Power Factor Improvement, it can help avoid or reduce power-factor-related electricity penalties.
An APFC panel is generally set to maintain a power factor around 0.95 to 0.99, depending on the utility requirement and system design. The target should be selected carefully to achieve efficient compensation without unnecessary overcorrection or leading power factor.
Common causes include capacitor overheating, excessive harmonics, incorrect sizing, poor ventilation, frequent switching, and loose electrical connections. Using properly rated components, suitable protection, adequate cooling, regular maintenance, and Detuned APFC Panel technology where required can improve reliability.
A standard capacitor bank may provide fixed or manually controlled reactive power compensation, while an APFC panel automatically switches capacitor stages according to the changing load. This automatic control provides more precise power factor correction and helps prevent under-compensation or over-compensation.
We focus on quality manufacturing, customized panel design, competitive pricing, testing, and timely delivery to meet different industrial and commercial requirements. Our experienced team and customer-focused approach help us provide dependable APFC Panel solutions tailored to individual electrical loads.
The required capacitor capacity can be calculated using the existing and desired power factors: kVAR = kW × (tan φ₁ − tan φ₂). For accurate sizing, the actual load profile, maximum demand, existing power factor, operating conditions, and harmonic levels should be assessed before finalizing the capacitor bank capacity.
