Product Description
Automatic voltage stabilizer with under voltage 
Automatic Voltage Stabilizer with Under Voltage
Working principle
Advanced technology of inductive regulation and oil-cooled method adopted,contactless intelligent RLS Series voltage stabilizers utilize A/D sampling voltage stabilizer' output via MCU,
and control the positions of rotor and stator,as per specified voltage precision, to stabilize output voltage;


Apply to varied precision machines.large electri equipments,large-scale lightings,production lines,school,hotels,hospitals,railways,Science R&D institutions,whole SEM(small-medium enterprises)and workshops of big large-scale enterprise,and so on.
