Zusammenfassung: | In a DC/DC stabilized voltage converting unit having a series circuit including an input filter, a converter stage having a control input and an output filter, the improvement comprising: a control stage having an output connected to the control input; a voltage regulating circuit receptive of an output of the output filter and having an output applied to the control stage; an anti-overvoltage and anti-overcurrent stage receptive of an output of the converter stage and having an output applied to the control stage; a voltage converter chain coupling circuit for effecting the linking of units in a chain; an internal monitoring and commutating circuit connected between the voltage regulating circuit and the control stage for surveying the outputs of the converter stage; a visually and electrically signalling alarm circuit receptive of the outputs of the output filter and having the outputs thereof applied to the chain coupling circuit; and wherein the chain coupling circuit includes a first input for linking to one pole of a power supply source, a coupling terminal connectable to said one pole of the power supply source, a third input for connecting to the coupling terminal of the next chain coupling circuit in the chain, first and second outputs connected to the input filter and a third output connected to the control stage. |
