Home/Products/Rustek 3XP Series Industrial Three-Phase Voltage Stabilizer
Industrial three-phase voltage regulation

Three-phase voltage stabilization from 60 to 150 kVA.

Rustek 3XP Series three-phase automatic voltage regulators are designed for factories, manufacturing plants, industrial machinery, workshops and commercial facilities. Available in 60, 80, 120 and 150 kVA models, the series provides independent voltage regulation for each phase, advanced FIFO step-switching technology and comprehensive protection against overvoltage, undervoltage, voltage fluctuations, overload, overheating and phase-sequence faults. With a wide 140–300 V input phase-voltage range, automatic and bypass modes, adjustable settings and LCD monitoring, the 3XP Series ensures stable, reliable power for demanding applications.
