SDV three-phase to high precision regulator
1. Overview APPLICATION
SDV series high-precision full-automatic three-phase AC stabilized power supply, composed of single-phase series high-precision automatic stabilized power supply, three-phase phase adjustment, to ensure the stability and safety of each phase voltage, the grid input is a three-phase four-wire system, Star (Y-shaped) connection method, the output can be three-phase four-wire system or three-phase three-wire system, three ammeters respectively indicate the output current of each phase, and a changeover switch and a voltmeter shift to detect the output line voltage of each phase. TNS series high-precision automatic three-phase AC voltage stabilizer with specifications of 20KVA and above is composed of three single-phase automatic voltage stabilizing power supplies with corresponding specifications and adopts self-coupling type.
This series of voltage stabilizers are suitable for small and medium-sized mechanical and electrical equipment, production lines, construction machinery, microcomputers, rust, air conditioners, refrigerators, stereos, televisions and other household appliances, lighting and other places that need voltage stabilization in the fields of industry, agriculture, medical treatment, radio and television, communication, scientific research, culture and so on.
