The Automatic Phase Corrector is a smart, microcontroller‑based device designed to monitor and correct the phase sequence in three‑phase electrical systems. It ensures that your motors and industrial equipment always run in the correct rotation, preventing damage, downtime, and operational inefficiency.
Equipped with automatic phase detection, single phasing protection, voltage imbalance monitoring, and auto-reset functionality, it provides hands-free, continuous protection for a wide range of industrial and commercial applications. LED indicators clearly display input and corrected phase status for easy diagnostics.
