Reactive Power Compensation: Instantly corrects inductive/capacitive reactive power demand, improving power factor to ≥0.99 and reducing energy losses.
Harmonic Mitigation: Suppresses harmonic distortions to THDi < 5%, protecting equipment from damage and ensuring compliance with global standards (IEEE 519, IEC 61000).
Three-Phase Unbalance Control: Balances load currents, enhancing system stability and extending equipment lifespan.
Rapid Response: <10ms reaction time to dynamic load changes, ensuring real-time compensation.
Flexible Configuration: Supports single-phase, three-phase three-wire, and three-phase four-wire systems with modular designs for easy scalability (up to 8 parallel modules).
Wide Operating Range:
Voltage: 220V, 400V, 500V, 690V (±20% tolerance)
Frequency: 50Hz (±5%)
Temperature: -20°C to +50°C, with humidity <90% (non-condensing).
Built to withstand harsh environments with IP20 protection and forced air cooling.
Low noise design (<60dB) and compact sizes for wall-mounted, rack-mounted, or cabinet installations (customizable for specific needs).
Phase Angle Detection: Monitors load current phase vs. voltage to identify lagging/leading reactive power.
Active Compensation: Generates opposite reactive current (leading for inductive loads, lagging for capacitive loads) to align current and voltage phases, achieving near-unity power factor.
Harmonic Filtering: Targets nonlinear load distortions, ensuring clean power supply.
