Product Overview

The MODERN range of AC Power Conditioner (Voltage Stabilizer/Voltage Regulator) are universally recognized as the finest range of servo-controlled voltage stabilizers. The units couple exceptional performance with unequalled build quality to provide an unmatched combination of reliability and versatility.

The units are designed to correct power quality problems like brownouts, surges, over-voltage, sags, voltage imbalance, unbalanced current, line noise etc. in the main power supply. Our Power Conditioner features voltage regulation, isolation, filtering, harmonic cancellation, transient suppression, surge protection, or any combination of these in a one-box solution.
