Power Factor Controlling Capacitors are generally switched by contactors. But due to this uneven switching of contactors, inrush currents get developed. These inrush currents decrease the life of capacitors. A contactor is a mechanical device, it has a definite life based on its number of switchings. Also due to mechanical contacts, there are limitations to switching time.

To solve these limitations of capacitor switching by contactors, SYCON has come up with thyristor switching modules. These modules are switched by zero-crossing detection algorithm.
