Overview

Advanced Voltage Protection

The YIY-AVC is an inverter-based system designed to protect sensitive industrial and commercial loads from voltage disturbances. It provides fast and accurate correction for voltage sags and surges, alongside continuous regulation and load voltage compensation. This system is optimally engineered to ensure equipment immunity from power quality events on the supply network without the need for batteries.
