Feature: 1. SWITCH STRUCTURE: The transfer switch is composed of 2 unit miniature circuit breaker, auxiliary contact, alarm contact, mechanical interlocking drive, controller and other components. 2. SINGLE MOTOR DRIVE: The dual power automatic transfer switch has a simple structure, which is driven by a single motor, has no noise, small impact, which is stable and reliable. 3. INTERLOCK FUNCTION: With mechanical and electrical interlocking function, it can supply power manually or automatically, the rated current of general and standby circuit breakers can be different. 4. STATUS INDICATION: Equipped with user terminal blocks, can reflect the circuit breaker status (open or closed). There are various indications on the panel, which is convenient and intuitive. 5. WIDE APPLICATION: With fine technology, the changeover switch has good isolation, less interference and stable performance, widely used in family, shopping mall, factory, laboratory, farm, etc. Specification: Item Type: Automatic Transfer Switch Model: SGQ1-63 2P Rated Current: 63A Rated Voltage: 230V AC Frequency: 50Hz Extreme Speed: 2P Rated Impulse Withstand Voltage: 4KV Insulation Voltage: 4000V 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 Transfer Switch1 x User Manual
