Product Description
RLS Series Contactless Intelligent Voltage Regulator

Product Introduction
    Known by its professional and reliable voltage regulator, the Kewang Technology Co.,ltd is one of the leading manufactures of electromagnetic devices in the word, and also a time-honored brand in China. The AVR, also Automatic Voltage Stabilizer, is one of the key products of our company. Actually, the Kewang Group got started with electromagnetic devices, like Transformers, Voltage Stabilizers, and Reactors in the 1990s. 
    The RLS Series AVR, built with top quality components and cutting-edge technology, has been provided to satisfy customers for more than 20 years both in China and oversea. With great flexibility and capacity to cope with the various conditions of the utility grid, it has been proved to be perfect power protector. Actually most of the RLS have been working continuously for more than 10 years or more without malfunction. 
With a considerable wide range of input voltage, it is able to cope with the various fluctuation of the grid, peak voltage, low voltage, surge, etc.  Always keep the output voltage stable, thus helping the voltage-sensitive equipment to operate properly. The oil immersed voltage stabilizer has the functions of phase failure, phase loss, over voltage and over-current protections; With inductive control, it could work with high efficiency, without mechanical wearing, no spark and maintenance-free.
     Our priority is to manufacture accurately every voltage stabilizer in order to achieve each Customer's full satisfaction.
    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.

    --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.
