Product Overview
WF·EL TNS-N-30KVA is a new generation three-phase intelligent separate phase high-precision fully automatic AC voltage regulator, specially designed for 380V/50Hz industrial power grid with serious three-phase unbalance problem.
It adopts advanced three-phase separate independent digital voltage regulation technology, each phase voltage is monitored and adjusted independently, which has extremely strong ability to adapt to unbalanced grid voltage. Equipped with high-definition LCD display to real-time monitor A/B/C three-phase voltage, current and operating status, automatically compensate grid voltage fluctuation. With full copper winding coil, low power loss, high efficiency ≥98%, complete intelligent safety protection system, it supports 7×24 hours continuous industrial operation, effectively protecting CNC machine tools, laser cutting machines, injection molding machines and other industrial equipment from unstable power supply damage.
