APFC Panels

Automatic capacitor-bank control for improved power factor and reduced reactive demand.

APFC Panels

What it does and
why it is used.

APFC Panels solutions are engineered around the approved single-line diagram, load schedule, protection philosophy and site operating requirement.

Monitors system power factor and automatically switches capacitor steps to maintain the configured target while protecting the capacitor bank and switching components.

  • Microprocessor APFC relay
  • Automatic capacitor stages
  • Contactor or thyristor switching
  • Detuned reactor options
  • Ventilation and protection
  • Metering and indication
  • Commercial buildings
  • Manufacturing facilities
  • Technology parks
  • Infrastructure projects
