It is an intelligent Power Factor Controller with 3 phase sensing and inbuilt intelligence to increase the capacitor life time by adapting capacitor switching information and ON time.
Unlike conventional power factor controllers which sense voltage from two phases and current from the other phase, Elmeasures IPFC is based on 3 phase sensing which renders it accurate for controlling power factor even an unbalanced condition
Available in 6,8 and 12 stages.
Applications
In all Incomers
Fixed power factor corrections individual (e.g. motor, transformers, lighting, etc.)
Group fixed power factor correction (several equipments connected in a group)
Capacitor banks of tuned and detuned
Harmonic trap applications (e.g. UPS, Frequency Drives and Converters, etc.)
Intelligent Power Factor Controlling based on the capacitor bank switching history (No of Operations, ON Time) - improves the capacitor life time
