AC voltage stabilizer
AEES
The STY, STT, 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.
STT and STY series are available for three phase network.
STT serie :
- Regulation on the average of the 3 phase.
- Withstand an unbalanced load of 50 %
STY serie :
- Independant regulation on each phase
- Withstands a total unbalanced load (100 %)
- Adjust the voltage assymetries betwwen phases.
