Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.Regulating autotransformersThe household adjusting autotransformer "ARB-400" has been produced by the Production Association "Elvo" since the 1st quarter of 1989. The autotransformer is used to manually maintain a relatively stable voltage of 220 volts with slow changes in the voltage of the electrical network from 150 to 250 volts with a load power of up to 400 watts. The indicator of the voltage of 220 volts is the extinguished LEDs. If the voltage in the network is less than the norm, the left LED lights up, more than the right one. The autotransformer can be used to power any electrical and radio-television equipment.
