Feature:1. Introduction: The dual power automatic transfer switch is composed of two unit miniature circuit breaker and accessories (auxiliary contact, alarm contact), mechanical interlocking drive, controller and other components.2. Easy Using: This auto switch has small volume, simple structure, convenient operation and long service life.3. Stable Work: The change over switch is driven by a single motor, which is stable, noiseless and has little impact.4. Status Display: A.T.S is equipped with user terminal blocks, which can reflect the circuit breaker status (open or closed); There are various indications on the ats panel.5. Powerful Function: With mechanical interlocking and electrical interlocking functions, it can be switched according to reliability, and can supply power manually or automatically. The rated current of general and standby circuit breakers can be different.6. Wide Application: This switch is widely used in families, shopping malls, factories, laboratories, farms and other scenarios.Specification:Item Type: Dual Power Automatic Transfer SwitchMode: SGQ1 63 2PMaterial: ABS, Aluminum AlloyRated Current: 63ARated Voltage: 230V ACFrequency: 50HzNumber of Pole: 2PRated 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 depend on the A phase and N wire of the incoming port of the common switch or the standby switch. Under the automatic state of two way power supply, when the voltages of the common switches of the incoming phase A and N circuits are normal (ac190-240v), the common switches are preferentially closed no matter whether the voltages of the common power supply B.C and the backup switches 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 switch A phase and line N have no voltage, and the incoming standby switch A phase and line N voltages are normal, whether the voltage of normal switch B and standby switch C is normal or not, the two way power supply is switched to standby. The power indicator and standby closed indicator are on. Manual function, regardless of whether the ordinary power supply and standby power supply have voltage, can be operated manually. During manual operation, the manual automatic button shall be placed in the manual operation position. The push handle rotates clockwise to the terminal, the standby power air switch R is open, and the public power air switch N is closed. When the push handle rotates counterclockwise to the terminal, the standby power air switch R is closed and the public power air switch N is open..Package List:1 x Dual Power Automatic Transfer Switch1 x Manual
