Industrial Variable Voltage Control Solutions for Stable & Reliable Power Systems

Variable Voltage Regulators, also known as Voltage Regulators, Voltage Stabilizers, AC Voltage Regulators, or Adjustable Voltage Regulators, are essential power control devices designed to automatically or manually adjust output voltage to a stable and precise level. By compensating for voltage fluctuations, load variations, and unstable grid conditions, variable voltage regulators protect electrical equipment, ensure consistent performance, and extend the service life of industrial and commercial power systems.

PowerNex Variable Voltage Regulators are engineered for continuous-duty operation across a wide range of voltages and capacities. Designed for single-phase and three-phase systems, our voltage regulation solutions are widely used in factories, production lines, laboratories, testing facilities, utilities, and infrastructure projects where stable voltage control is critical.
