APF 3P3W/3P4W-RM Series 50A–200A Rack Mount Active Power Filter

Main Functions：

• Harmonic Filtering: Supports 2–51 order harmonic suppression under single harmonic filtering mode; priority mode focuses on 2–13 primary harmonics;
• Multi-mode Priority Setting: Customizable priority modes including H+Q, Q+H, Q+H+B, H+Q+B (H=Harmonic, Q=Reactive Power, B=Unbalance);
• Dynamic Reactive Power Compensation: Smooth continuous reactive power regulation, lift power factor above 0.95 to eliminate reactive power penalty and reduce transformer & line loss;
• Three-phase Unbalance Correction: Balance three-phase load current and reduce neutral line overheating;
• Resonance Suppression: No system resonance or harmonic amplification risk when matched with passive capacitor banks;
• Comprehensive Protection: Full protection against overvoltage, undervoltage, overcurrent, IGBT failure, phase loss, over-temperature and communication faults;
• Parallel Expansion: Max. 5 units parallel operation in one system, customized expansion available;
• Remote Monitoring: Standard RS485 communication port with Modbus protocol for remote data collection and operation monitoring.
