Product Description
Most Populart High quality AC fully automatic stabilizer
SBW/DBW series Automatic voltage regulator is designed to stabilize the AC voltage. Our highlight of design is by using the superposition principle, compensation method to make the most of the stability of the system output power directly from the power grid.When the grid voltage fluctuation or load changes caused by the voltage fluctuation, can automatically maintain the stability of voltage output. We have variety, complete specifications of such kind of products with small volume, light weight, load wide adaptability, no additional additional waveform distortion, high reliability and can work continuously for a long time, convenient in operation and maintenance. Widely used in industrial and mining enterprises, household appliances, medical equipment, mechanical processing, testing equipment, elevators, school, etc.
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.
