Three-phase voltage stabiliser STS-5-120-380-A-U3

STS-5 120 kVa - three-phase industrial voltage stabiliser with energy-saving function, increased mechanical strength and unique ability to operate in harsh climatic conditions. Three-phase voltage stabiliser STS-5 is designed for automatic and simultaneous stabilisation of inter-phase (380V) and phase (220V) voltage in the AC network with deaf-earthed or insulated neutral in unstable power grids, in severe climatic conditions and in continuous power supply mode. The stabiliser allows operation in non-symmetrical modes, in which the load current non-symmetry is from 5 to 100% and the supply network voltage non-symmetry is from 2 to 20%.
