Low-Voltage Integrated Power Quality Management Cabinet

Low-Voltage Integrated Power Quality Management Cabinet

One-stop integrated solution combining capacitors, SVG, and APF to comprehensively address reactive power and harmonic issues.

Get in touch→

Modular Design: Independent, compact power units for easy installation and maintenance. Ratings: 100~400kvar (reactive) and 30~150A (harmonic). Parallel operation: one unit fails, others keep running – high reliability.
PF = 1 Correction: Compensates both capacitive and inductive reactive power with continuous output, error <1%.
Harmonic Filtering: Filters 2nd–50th harmonics from nonlinear loads, improving power quality and equipment safety.
Unbalance Compensation: Corrects three-phase unbalance and excessive neutral current.
Fast & Reliable: Proprietary tech: 80kHz switching, 6kHz current loop bandwidth, response <10ms.
Flexible Use: Mix and match units: parallel for capacity expansion, reactive+harmonic combined, or passive phase-shifter to avoid resonance.
Easy Install & Maintain: Supports grid/load side CT sampling. Rack-mounted units, clear HMI alarms, and modular swap of faulty units.
