Automatic Line Voltage Regulator

Linear Voltage Regulators work on the same principle as Servo Voltage Stabilizers.

Output Voltage is monitored continuously and compared to a reference Standard Voltage. The deviation actuates a servo mechanism whereby a small voltage is added or subtracted to Mains Voltage to obtain a stable Output Voltage which remains within ±1 % of the set Output Voltage. Thus for a Mains variation of 300 - 500 Volts (depending on the range of the Linear Voltage Stabilizer), the Output voltage is maintained automatically at 400 ± 1 %.

ieco Linear Voltage Regulators are predominantly meant for Balanced Mains-Balanced Load type of industrial or large-power installations where equipment is mostly three Phase Machines / Motors. These Regulators have linear auto-variable transformers with Rolling Contact carbon brushes. Linear topology facilitates vertical configuration. As a result, the footprint is small compared to Toroidal type of Servo Voltage Stabilizers.
