TND/TNS three-phase Voltage Stabilizer
Overview
TND/TNS series high-precision automatic three-phase AC stabilized power supply is composed of single-phase series high-precision automatic stabilized power supply. , star (Y-shaped) connection, the output can be three-phase four-wire system or three-phase three-wire system, the output current of each phase is indicated by three ammeters respectively, and each phase is detected by shifting a switch and a voltmeter. output line voltage.
TNS series high-precision automatic three-phase AC voltage stabilizer of 20KVA and above specifications is composed of three single-phase automatic voltage stabilized power supplies of corresponding specifications, and adopts self-coupling type.
This series of voltage stabilizers are suitable for small and medium-sized electromechanical equipment, production lines, construction machinery, microcomputers, rust, air conditioners, refrigerators, audio, TV and other fields in the fields of industry, agriculture, medical treatment, radio and television, communication, scientific research, culture, etc. Household appliances, lighting and other places that require voltage regulation.
