Feature:
1. Automatic and Manual: This dual power supply auto switch not only supports automatic mode, but also can be operated by manual button for easy operation and reliable performance.
2. Working Process: When one power supply fails, the power auto switch automatically connects one or more load circuits from one power supply to the other automatically to ensure normal power supply load circuits.
3. Multiple Protection: The dual power supply auto switch has high load power switching speed and safe switching with load. Support a variety of protection functions, including short circuit, overload, phase loss, under voltage protection.
4. PC and Silver and Brass: The automatic power switch is made of flame retardant PC material, which is well insulated, high temperature resistant, anti aging, safe and reliable, and uses silver contacts and brass motor coils.
5. Easy Installation: This ATS automatic switch has a compact structure, reliable transmission, easy installation and maintenance, screw mounting, vertical or horizontal installation, and convenient and reliable power installation.
6. Use Scene: This switch is mainly used for AC220V voltage conversion, such as hospitals, stores, banks, chemical industry, metallurgy, construction and other important situation where power failure is not allowed.

Working Principle
The series dual power supply controller and drive mechanism power supply signal depends on the A phase and N line of the common switch or standby switch inlet port. When the dual power supply is in automatic state, when the voltage of incoming phase A and N common switch is normal (AC190-240V), the common switch will be closed in priority regardless of whether the voltage of common power B.C and standby switch a.b.c and N is 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, regardless of whether the normal switch B and standby switch C have normal voltage, the dual power supply turns to standby closure. The power indicator and standby closure indicator are on. Manual function, regardless of whether the voltage of normal power supply and standby power supply is available or not, manual operation mode can be used. For manual operation, the manual automatic button should be placed in the manual operation position. Push the handle to rotate clockwise to the terminal, the standby power vac open R open, the common power vac open N close. When pushing the handle to rotate counterclockwise to the terminal, the standby power switch R closes and the public power switch N opens.

Note:
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.
