Dynamic harmonic suppression - Full-band compensation of the 2nd to 50th harmonic, with selective order setting based on the site spectrum; at rated conditions the grid-side total harmonic distortion of current (THDi) can be reduced to below 5%.
Continuous reactive compensation - Bidirectional (capacitive and inductive) stepless output, eliminating the over-compensation, under-compensation and switching transients of stepped capacitor banks; power factor after compensation can reach 0.99 or better.
Three-phase unbalance correction (optional) - Per-phase compensation of negative- and zero-sequence components in three-phase four-wire systems, reducing neutral current and voltage unbalance.
Modular parallel expansion - Each cabinet comprises independent power modules and supports multi-cabinet paralleling, so capacity can be added as required; if one module fails, the remaining modules keep running for higher availability.
Smart monitoring and HMI - The touch screen displays voltage and current waveforms, harmonic spectrum, THD, power factor, module status and event logs in real time; RS485/Modbus-RTU is standard, with Ethernet, 4G and cloud-based remote service as options.
Comprehensive protection - Over-current, short-circuit, over-voltage, under-voltage, over-temperature, phase loss, DC-bus abnormality and fan-failure protection and alarms; the unit blocks and trips automatically on fault without injecting disturbance into the system.
No resonance risk - Active injection does not alter system impedance, so the cabinet can operate alongside existing capacitor-compensation banks.
