50Hz RLS 380v Phase 200KVA  Automatic Voltage Regulator
Introduction:
RLS series voltage stabilizer (AVR)is designed in advanced inductive and digital control system to stabilize the output voltage within requirement. The oil immersed voltage stabilizer has the protection functions of phase failure, phase loss, over voltage and over-current. Its main circuit has the characteristics of contactless voltage regulation, no mechanical wearing, no spark, no interference and low failure rate. In addition, this voltage stabilizer has the advantages of high impact resistance, super strong instantaneous overload capacity and long service life. The capacity is from 100KVA to 2500KVA.
 
Application:
COMMERCIAL: High-rise building, elevator control, large A/C chillers, lighting, and other sensitive critical systems.
INDUSTRIAL: Industrial automation, production lines, CNC, factory robotics, heavy load machinery, precision machinery.
MEDICAL: X-ray, CT scanner, MRI system, Radiation therapy machine, other medical imaging equipments.
TELECOM: Data exchange center, Mobile base stations, control centers and transmission relay stations.
 
Features:
--Auto/Manual operation and manual regulation functions.
--LED display for input voltage, output voltage, output current.
--Digital MCU is controlling output voltage. Voltage precision is adjustable.
--Contactless carbon brush, High Reliability and strong resistance ability to overload.
--Stepless voltage regulation to stabilize output voltage.
--Good adaptability to variant loads and ambient.
  
Application Environment:
Installation site should be no serious effect on the transformer insulating gas, steam, chemical deposition, dust, dirt, and other explosive corrosive medium; It cannot be installed in a condition of significant vibration turbulence.
