Autotransformer AOSN-20-220 UHL4 5 0kVA 20A adjustment range 0-250V IP20 Elektrotekhnik ET556153

AOSN series autotransformers are designed to maintain stable voltage in industrial power grids. They are used in laboratory research and in commissioning works. They are used for voltage regulation in muffle furnaces and thermostats. The AOSN autotransformer allows for smooth adjustment of the output voltage from 0 to 250V under load. The rated load current of the AOSN autotransformer, depending on the model, is 2, 4, 8, 20A. Rated primary voltage is 220V. The rated power of the AOSN autotransformer, depending on the model, is from 0.5 to 5kVA. All models feature a graduated scale and a voltmeter displaying the output voltage.
