The dual power automatic switch is a newly developed miniature household power switch,which is mainly used to test whether the main power supply or standby power supply is normal.When the normal power supply is abnormal,the standby power supply starts to work immediately,which ensures the continuity,reliability and safety of power supply.This product is specially designed for household rail installation and is specially used for PZ30 distribution box. The dual power automatic switch is suitable for emergency power supply systems with 50 or 60Hz and rated 400V AC.ATS has the characteristics of solid structure, reliable conversion,convenient installation and maintenance and long service life. It is widely used in various occasions where power failure cannot be sustained,and can be operated by electricity or manually.ATS is composed of TSE and controller According to GB/T14048.11,Part 6-1:mulifunctional equipment and switchgear is formulated.It can be seen that ATS is the most qualified low-voltage switchgear and control device
2.Normal operation time and installation conditions
2.1 Ambient air temperature
The maximum temperature shall not exceed 40ºC,the minimum temperature shall not be lower than -5ºC,and the average temperature within 24 hours shall not be higher than 35ºC.
2.2 Altitude The altitude of the installation site should not be higher than 2000m
2.3 Atmospheric conditions When the maximum temperature reaches 40ºC,the relative humidity of the installation site should not exceed 50%;when the temperature is the minimum tem -perature-5ºC,the relative humidity is higher,for example,the temperature is 25ºC, and the relative humidity is 90%.Due to the temperature change,special measures should be taken to deal with the occasional condensation on the surface of the product.
2.4 Pollution grade The pollution grade of ATS conforms to grade 3 specified in GB/T14048.11.
2.5 Installation category The installation type of ATS conforms to the category specified in GB/T14048.11. 2.6 Installation conditions ATS can be installed vertically in control cabinet or distribution cabinet.Make sure the installation distance meets the requirements in Figure 1.
