Power Factor Correction (PFI)

The Varlogic controllers permanently monitor the reactive power of the 
installation and control the connection and disconnection of capacitor 
steps in order to obtain the targeted power factor. 

Performance 
■ Permanent monitoring of the network and equipment. 
■ Information provided about equipment status, 
■ Alarm signals transmitted in case of anomaly 
■ Communication by Modbus protocol. 
■ New control algorithm designed to reduce the number 
of switching operations and quickly attain the targeted power factor. 
Simplicity 
■ Simplified programming and possibility of intelligent self-set-up. 
■ Ergonomic layout of control buttons. 
■ Quick and simple mounting and wiring. 
■ A special menu allows controller self-configuration. 
User-friendliness 
The large display allows: 
■ Direct viewing of installation electrical information and capacitor stage condition. 
■ Direct reading of set-up configuration. 
■ Intuitive browsing in the various menus (indication, commissioning, configuration). 
■ Alarm indication.
