AC voltage stabilizer
230 - 400 V, 0.7 - 230 kVA
AEES
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.
