Product Overview
The Voltainer three phase air cooled servo stabilizer continuously monitors incoming supply and corrects it through a servo-driven variac and buck-boost transformer. The result is a steady 415 V ±1% output, even when the grid swings between 340 V and 480 V.
Every unit is built around a copper-wound variac and transformer, a digital servo voltage controller with metering on the front panel, and a full set of protections — so your motors, drives and controllers are shielded from the damage that unstable voltage causes.
