Feature: 1. Dual Mode: The automatic transfer switch not only supports automatic mode, but can also be operated via manual buttons for simple operation and reliable performance. In the event of a fault in one power supply (only normal A phase voltage and standby A phase voltage are tested, only loss of voltage or phase), it automatically connects one or more load circuits from one power supply to another automatically to ensure the normal supply of load circuits.2. Quick Switching: The automatic transfer switch has a quick switching speed with load power, safe switching with load, the maximum switching speed is less than 2 seconds, under regular circumstances can achieve the use of electricity part of the appliances without power. 3. Protection Functions: The automatic changeover switch supports various protection functions, including short circuit, overload, phase loss and low voltage protection. 4. Easy Installation: The automatic transfer switch is compact, screw mounted and can be installed vertically or horizontally for easy and reliable power supply installation. 5. Excellent Material: The automatic transfer switch is made of excellent flame retardant PC material, reliable insulation, withstand strong temperature, ageing resistance, safe and reliable, the use of silver contacts, brass motor coil can greatly improve the conductivity and service life of the product. 6. Broad Applications: The automatic changeover switch can be used in a wide range of applications, generally at home and especially in important places where electricity is used, such as hospitals, banks and factories where power cuts are not allowed. Specification: Product Name: Dual Power Automatic Transfer Switch This series of dual 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 dual 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 dual 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 operation, 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. Package List: 1 x Dual Power Automatic Transfer SwitchNote: Installation Environmental Conditions: 1, The maximum surrounding temperature should not exceed 40°C, the minimum should not be lower than ‑5°C, and the average temperature within 24 hours should not be higher than 35°C. 2, The altitude of the installation site should not be higher than 2000m. 3, When the maximum temperature reaches 40°C, the relative humidity of the installation site should not exceed 50%; when the temperature is the minimum temperature ‑5°C, the relative humidity is higher, e.g. 25°C, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation above the product. 4, Low level of pollution, no serious vibration and shock, no corrosive environment, no serious dust, no conductive particles and explosive hazardous substances, no strong electromagnetic interference. |
