Double Power Automatic Transfer Switch AC230V 100A 2P ATS Mini Generator Changeover Switch Product Name: Double Power Automatic Transfer Switch Material: PC flame retardant, brass, pcb, silver Current: 100A Working Frequency: 50Hz Rated Voltage: AC230V Working Voltage: AC220V Display Function: Indicator light display Operating Mode: Automatic manual ATS Level: CB level Conversion Time: ≤2s Use Level: AC 33iB Switching Mode: Automatic switching and automatic recovery Conformity with Standards: IEC947-6-1GB14048.11 Working Principle: This series of double power supply controller and drive mechanism supply signal depends on the A phase and N line of the incoming port of the common switch or standby switch. When the double power supply is in automatic state, when the incoming phase A and N common switch voltage is normal (ac190-240v), the common switch will be closed in priority regardless of whether the common power supply B.C and the standby switch a.b.c and N voltage are normal. At the same time, the power supply indicator and the common off indicator light up. When the incoming public switch A phase and line N have no voltage, and the incoming standby switch A phase and line N have normal voltage, the double power supply turns to standby closure regardless of whether the normal switch B and standby switch C have normal voltage. The power indicator and the standby closure indicator light up. Manual function, regardless of whether the normal power supply and standby power supply have voltage or not, can be operated manually. For manual operating, the manual automatic button should be placed in the manual operating position. Push the handle clockwise to the terminal, the standby power supply is open R and the common power supply is open N. When the push handle is rotated counterclockwise to the terminal, the standby power switch R closes and the public power switch N opens.
