Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.RectifiersSelenium rectifier "VS 4-12" presumably since 1975 has been produced by the Leningrad plant "Elektrodelo". The BC serves to convert the alternating voltage of the electrical network 127 or 220 V with a frequency of 50 Hz into a constant pulsating voltage from 4 to 12 V, adjustable abruptly, with a current strength of up to 3 A. It is intended for staging various demonstrations, laboratory work and a physical workshop in general educational institutions ...
