Voltage stabilizers
Single and three phases
The automatic voltage regulators provide voltage stabilisation from instable networks single phase
(STM) or three phases (STY) even with important phases voltages assymetry and/or important unbalanced load.
The STY, 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.
Benefits
STY serie:
Independant regulation on each phase.
Withstands a total unbalanced load
(100%).
Adjust the voltage assymetries
between phases.
