Product Description
Oil immersed Type Contactless Voltage Stabilizer 200KVA

RLS series voltage regulator is designed by advanced technology and digital control system to stabilize the output voltage within specific range. The RLS regulator has the advantage of high impact resistance, super strong instantaneous overload capacity and long service life.

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.

1. Contactless without carbon brush friction;
2. Integrated circuit with reliable function for voltage regulation;
3. High efficiecy more than 98%;
4. Protection system: over load, over voltage, short circuit protection;
5. Higher precision,longer cycle life,more stable voltage;
6. Low loss and maintenance-free for a long time.
