Today appears all anymore and more devices-users of electric power. But the present to date electric systems already can not get along at such amount of users of electric power in spite of the fact that many producers already passed to the new technological level and produce the equipment of enhanceable economy.

   Usually it is caused  by the local overload of part of network or with banal old age of this network. As a result supply pressure can fluctuate from 160V to 250V (and even wider), that negatively tells on work of equipment (namely - abbreviates the term of service of equipment), and at times even results in instantaneous death this equipment.

   Especially sharply this problem stands in villages, out-of-town areas, summer residence areas.

   Exactly here the stabilizators of tension come for help. A stabilizator of tension (Automatic regulator) is a transformer of electric energy, allowing to get on an output tension, being in the set limits at the considerably large vibrations of entrance tension and resistance of loading.
