Product Overview
WF·EL TNS-Z-20KVA is a high-efficiency three-phase intelligent high-precision fully automatic AC voltage regulator, specially designed for 380V/50Hz industrial power grid. It adopts advanced servo motor automatic compensation voltage regulation technology, real-time monitors A/B/C three-phase voltage, current and frequency through high-definition color LCD display, automatically compensates grid voltage fluctuation and three-phase unbalance problems.
With full copper winding coil, low power loss, high efficiency ≥98%, and complete overvoltage, undervoltage, overload, short circuit, phase loss protection functions. It supports 24 hours a day, 7 days a week continuous industrial operation, effectively protecting CNC machine tools, laser cutting machines, injection molding machines and other precision industrial equipment from unstable power supply damage.
