Introductions of product
TNS three phases fully automatic voltage regulator is combination of three SVC high function single phase automatic voltage stabilizers,the incoming power of power network is three phases four wires system,the output power is also three phases four wires with three electric meters to indicate three phases current separately,and a shift switch&voltage meter to shift and test each output voltage.

usage situations
Widely used in most situations where the voltage stabilization is required
