2P Automatic Transfer 230V 63A Dual Power Generator Transfer Selector for Shopping Malls and Factories

Introduction: The dual power automatic transfer is composed of two unit miniature circuit breaker and accessories (auxiliary contact, alarm contact), mechanical interlocking drive, controller and other components. Easy Using: This auto has small volume, simple structure, convenient and service life. Stable Work: The change over is driven by a single motor, which is stable, noiseless and has little . Item Type: Dual Power Automatic Transfer Mode: SGQ1 63 2P Material: ABS, Aluminum Alloy Rated Current: 63A Rated Voltage: 230V AC Frequency: 50Hz Number of Pole: 2P Rated Impulse Withstand Voltage: 4 (KV) Insulation Voltage: 4000 (V) Working Principle: The power supply signals of the dual power supply controller and drive mechanism of this series on the A phase and N wire of the incoming port of the common or the standby . Under the automatic state of two way power supply, when the voltages of the common es of the incoming phase A and N circuits are normal (ac190-240v), the common es are preferentially closed no matter whether the voltages of the common power supply B.C and the backup es a.b.c and N are normal. At the same time, the power LED and the common off LED are lit. When the incoming public A phase and line N have no voltage, and the incoming standby A phase and line N voltages are normal, whether the voltage of normal B and standby C is normal or not, the two way power supply is ed to standby. The power indicator and standby closed indicator are on. Manual function, regardless of whether power supply and standby power supply have voltage, can be operated manually. During manual , the manual automatic button shall be placed in the manual position. The push handle rotates clockwise to the terminal, the standby power R is open, and the public power N is closed. When the push handle rotates counterclockwise to the terminal, the standby power R is closed and the public power N is open.
