FIELD: electricity. ^ SUBSTANCE: second (6) and third (9) diodes are connected oppositely in series. Besides, the point of connection of their cathodes via serially connected first resistor (7) and the stabilitron (8) is connected to the base of the transistor of n-p-n type (5), the anode of the third (9) diode is connected to a positive output of the reserve source of supply (4). ^ EFFECT: reduced consumption in a redundancy mode, higher reliability of the device, simplified circuit solution. ^ 2 dwg |
