SYCON-66 XX SS - Automatic Power Factor Controller

Sycon 66 XX SS

This advance version in 66 series with small volume and light weight, displays all parameters like system power factor voltage, current, system KVA, system KVAr, system KW, shortfall KVAr, THD. It works on smart switching algorithm where a number of capacitors can be turned ON or OFF instantaneously used on the capacitive KVAr requirement. It also displays harmonics from 3rd to 13th. It has capability to auto-identify the capacitor values. All the settings are password protected. It has in-built capacitor protection system in case of harmonic overload and over-voltage. With in-built TEST mode, the panel can be tested without CT current.


Large alphanumeric LCD display (2 x 16 characters)
