Tronic Three Phase Servo Digital 100KVA Voltage Stabilizer, 400V Output

Our review

This Tronic unit is a three-phase servo digital stabilizer rated at 100kVA, delivering a 400V output while accepting input from 320V to 470V AC. That wide window is the point: where the supply sags or surges, connected machinery keeps seeing steady voltage, which cuts wear and reduces unplanned downtime. It suits workshops, processing plants, and other sites running three-phase industrial loads rather than a single machine or a home. Before buying, confirm your total connected load and starting currents stay within 100kVA, check whether your supply is genuinely three-phase, and plan for ventilation and floor space, since units of this class are heavy and generate heat. Compare against other servo-type stabilizers by input range, output accuracy, and how well their capacity matches your actual load; an oversized or undersized unit helps less than a correct match. It is available on Sokonia.
