SYCON-66 XX - Automatic Power Factor Controller

Sycon 66 XX

This version of 66 XX series displays all parameters such as power factor, shortfall KVAR Excess KVAR , voltage, current and THD all at a time. By selection, it displays % harmonic from 3rd to 13th and capacitor values. It has built in facility to cut-off the capacitors in case of harmonic overload. It has password protected settings. It’s built-in TEST mode enables to test the panel without CT current. Auto as well as Manual mode of operation are available in this relay.
