The Compact Activar/Equalizer are static/dynamic VAR compensation systems for transient-free power factor correction and dynamic load compensation. Traditional 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.
By compensating voltage drops, harmonics, voltage flickering & fluctuations, our systems 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.
