A Thyristor-Based APFC Panel (Automatic Power Factor Correction Panel) is an advanced electrical control panel designed to improve power factor using thyristor switching technology for capacitor banks. Unlike traditional contactor-based panels, it allows instant, noise-free, and arc-free capacitor switching, making it ideal for industries with fast-changing loads like welding, CNC, elevators, or printing machines.

Features:

• Uses thyristor switches (SCRs) to connect/disconnect capacitor banks.
• Provides real-time, rapid reactive power compensation.
• Works without mechanical wear (no contactors = low maintenance).
• Ideal for harmonic-rich or rapidly fluctuating loads.

Components:

• Thyristor modules (SCR-based)
• Power capacitors
• Detuned reactors (optional, for harmonic filtration)
• APFC relay/controller
• Current Transformers (CTs)
• MCBs/MCCBs/SPDs for protection
• Cooling fans or ventilation system
