Service connection amplifier for signals transmitted over high frequency line has emergency power supply with accumulator with rated voltage corresponding to amplifier working voltage

摘要

The service connection amplifier has an amplifier (102), an amplifier power supply stage (104) with an alternating current connection (114) for supplying the amplifier with a direct voltage and an emergency power supply (124) with an accumulator (128) whose rated voltage corresponds to the working voltage of the amplifier. AN Independent claim is also included for the following: an emergency electrical supply for a domestic connection amplifier.
