Voltage stabilizers

The automatic voltage regulators provide voltage stabilisation from instable networks single phase (STM) or three phases (STT) even with important phases voltages assymetry and/or importance unbalanced load (STY).

The STY, STT and STM series voltage regulators are equipped with an electronic sensing circuit which controls a motor driven variable autotransformer. This one feeds a buck-boost transformer connected in series between the supply and the load in order to regulate the voltage.
