KVARBOX-A is an advanced Static Var Generator with Active Filtering (ASVG) for a comprehensive 2-in-1 power quality solution. This module reliably eliminates 2nd to 25th odd harmonics with a filtering efficiency exceeding 90–97%. It features a robust 3L IGBT architecture and an ultra-fast response time (≤ 5 ms). It provides maximum protection even for facilities with a high density of non-linear loads (frequency converters, LED lighting, switched-mode power supplies).

Lightning-fast response to grid fluctuations: The total device response time is under 40 ms (< 40 ms). The ASVG can immediately react to sudden load changes in the grid and prevent power supply destabilization.
High energy efficiency: System efficiency reaches ≥ 97%. For facilities (such as hospital campuses), this means minimal thermal losses during compensation and significant electricity cost savings.
Wall-mount design: These are wall-mount modules that can be easily installed on a wall using mounting brackets.

Key Applications

Reactive power compensation, phase load balancing + active harmonic filtering for:

Low-voltage substations
Manufacturing and industrial plants
Buildings with dynamic or variable loads
Applications with high power quality requirements
