Patent ID: 8415822

Claim:
A device for regulating the voltage level at a desired section of a telecommunications network, said device comprising: an input port, connected to a portion of said network and receiving an input RF telecommunications signal with an input AC voltage; isolating circuitry, connected with said input port, for isolating said input AC voltage from said input RF telecommunications signal; a step-up transformer, connected with said isolating circuitry, said transformer comprising a primary winding receiving said isolated input AC voltage and a secondary winding having a phase-output serially connected to the phase-input of said transformer primary winding; a plurality of relays, connected to respective points of said secondary winding of said transformer, said relays operative for providing a selected voltage gain by selectively switching on a connection from said secondary winding of said transformer, thereby deriving a regulated AC voltage at a predetermined level; control circuitry, connected with said transformer and with said relays, said control circuitry operative for monitoring said input AC voltage, and selectively activating a selected relay while deactivating the other relays, to provide said selected voltage gain; recombining circuitry, connected with said relays, for recombining said regulated AC voltage with said isolated input RF telecommunications signal to produce a recombined regulated AC voltage and RF telecommunications signal; and an output port, connected to said recombining circuitry and to another portion of said network, said output port providing said recombined regulated AC voltage and RF telecommunications signal to said another portion of said network.
