Stabilized source of anode voltages "SIAN".

Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.Blocks and power supplies laboratoryThe stabilized source of anode voltages "SIAN" has been produced presumably since 1950. The source is intended for laboratory work related to the development and testing of vacuum tube radio equipment. The source has four output voltage limits. 150 V, where the output voltage is continuously adjustable from 80 to 150 V. 220 V, where adjustment is possible from 100 to 240 V. 290 V, where adjustment is possible from 130 to 320 V and 360 V, where adjustment is possible from 160 to 400 V. The load current must not exceed 300 mA. There are unregulated AC filament voltages: 4 and 6.3 V; at a load current of up to 6 A.
