The Circutor Computer C12 Wi-Fi (code R14842) is a 12-step power factor controller with built-in Wi-Fi communications, designed for reactive power compensation in balanced low-voltage installations. It operates from a 400 V AC supply and controls up to 12 contactor-switched capacitor steps, while showing up to 27 electrical parameters on its high-contrast panel-mount display. A dedicated alarm relay and up to 12 user-configurable alarm thresholds support continuous monitoring and control of installation performance.
