Voltage stabilizer is a electronic device intended for maintenance at certain level (stabilisation) of an alternating voltage. Stabilizer can be applied in industrial and household networks of an electrical supply with nominal voltage of an alternating current 220 volt frequency of 50 Hz (a single-phase variant).
All models of stabilizers have digital light-emitting diode indication of key parametres and modes, and in separate models possibility of operative change of some parametres by the user.
