Elspec’s Equalizer is the world’s fastest transient-free power factor correction  system used in shipyard cranes, motor starting and a variety of other applications that have rapidly fluctuating loads requiring complete power factor correction in less than one network cycle.

The Activar solution provides transient-free, full power factor correction in just a few seconds.  Along with extending the life of the entire compensation system, this Elspec technology also enables customers to use the device as a harmonic filter and save energy while monitoring all network power parameters through the built-in power quality analyzer.
