Improves power factor

continuously outputs and compensates reactive power to maintain power factor > 0.99. The  compensation performance is 1.2 times better than a traditional compensation device (capacitor)

Suppresses harmonics

configures the required amount of reactive current in real-time and compensates the reactive power to filter high order harmonics

Immediate reaction

immediate configuration capability provides immediate analysis and reaction time. Provides cycle reaction < 15ms and dynamic reaction < 50us.

Low voltage benefits

output current is not affected by the mains voltage fluctuation, providing stable support for mains voltage.

Low consumption rate and high operation efficiency

adopts new standard IGBT with low power consumption rate and improves full set device efficiency up to 99%. The system provides low power consumption.

Modular design, easy extension

no need for additional reactor or capacitors and the compact design reduce volume by 50%-60%. It is easy to maintain with a specially designed air path that facilitates module assembly and extension.

Highly reliable and safe

Robust design for power system eliminates resonance problems, with no more amplified harmonic current and voltage. It extends components' life cycle and protects the system.
