Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.Surge ProtectorsFerroresonant voltage stabilizer "Sabit" (FSN-200), presumably since 1962, has been produced by the Baku plant "Elektrobytpribor". The stabilizer is designed to maintain a voltage of 220 volts at the output, when it changes in the network from 154 to 253 volts. Maximum load power 200 W. The mass of the device is 8 kg. Presumably, since 1968, the plant has been producing a stabilizer similar in design and design under the name "Sabit-2" (model 2).
