A consumer power back-up-DC stabilizer comprises the first and second regulating elements connected to bipolar power buses, current driving two-terminal-pair networks, a reference voltage element, an output voltage measuring division device, an optoelectronic element and a feedback amplifier, the input transistor base being connected to a reference voltage element, its collector is connected with an input bus of corresponding polarity. The feedback amplifier input transistor collector through an additional resistor is connected with an input transistor collector, directly connected with an additional transistor base, the emitter being connected with an input transistor collector. The collector through an optoelectronic element emitting diode is connected with an opposite polarity input bus. |
