APFC panels automatically switch capacitor steps to improve power factor and reduce penalties caused by excessive reactive power demand.
What power factor means
Power factor shows how effectively electrical power is converted into useful work. Low power factor increases reactive demand and can attract penalties from utilities.
How APFC works
An APFC panel senses power factor and switches capacitor banks in steps to compensate reactive power. This helps maintain target power factor as plant load changes.
