Sources of alternating current '' B2-2 '' and '' B2-3 ''.Power supplies. Rectifiers, stabilizers, autotransformers, transient transformers, etc.Blocks and power supplies laboratorySources of alternating current "B2-2" and "B2-3" were produced presumably since 1982. The models differ only in the output power of 500 and 1000 V * A, respectively. IPT "B2-2" and "B2-3" ensure the maintenance of a constant supply voltage (220 V, 50 Hz) of precision electronic (measuring) equipment. Parallel operation with devices of the same type is possible. Power consumption 550 VA (B2-2); 1200 VA (B2-3). The overall dimensions of any stabilizer are 435x130x235 mm. Weight 20 kg.
