Compact Activar/Equalizer

Compact Reactive Power Compensation Unit

The Compact Activar/Equalizer are static/dynamic VAR compensation systems for transient-free power factor correction and dynamic load compensation. Traditional power quality systems are often larger, complex and expensive. Our compact systems emerge in response to these challenges for industrial and commercial sectors with limited space. With only 120(H) x 102(W) x 76(D) cm, our system’s footprint is the most efficient design offered by Elspec. As all Elspec’s power quality solutions, our compact systems are compensating the voltage, harmonics, voltage flickering & fluctuations, at zero-crossing. This makes them the fastest Power Factor correction systems. Our power quality solutions enhance machinery lifetime and improve production efficiency. Our compact cost-effective design offers easy upgradability, and modularity. The unique modular design enables system extensions including hybrid layout for integrated active harmonic filtration.
