Staco Energy Products’ StacoVAR mini is a wall-mountable automatic power factor correction bank that maintains the desired power factor level using the microprocessor-based controller to adjust to system-load conditions. It has rugged metalized polypropylene dry-type capacitors in a compact enclosure. Capacitor-rated contactors with damping resistors reduce back-to-back switching currents. The unit accurately regulates power factor automatically.
