Why do supermarket anti-theft devices use independent power supplies?
Many people have seen a supermarket anti-theft device. It is used to prevent the theft of goods in the supermarket; generally we will pass by it when importing and exporting. Of course, those of us who pass by may not know much about him, but we don’t know much about it. The merchants who deal with all day need to know a lot; I believe that many merchants will be forced by the manufacturer’s engineers to require an independent power supply for the power supply of the anti-theft device during installation. Many people don’t know the reason. Today I will tell you about the power supply of the supermarket anti-theft device. Why do you need an independent power supply? Come and take a look.
When installing supermarket anti-theft devices, many businesses set the power supply of the supermarket anti-theft device to the same power supply as other electrical appliances. This may save a lot of economic expenditure in terms of installation and wiring fees, but it will provide the entire supermarket with electricity safety. A landmine was planted. I believe that many merchants who do not use independent power supplies have encountered the situation that the total power supply in the supermarket is burned out and the power supply with the anti-theft device is also burned out. If the anti-theft device and other electrical appliances in the supermarket use the same power supply, when those refrigerators, freezers, When high-power appliances such as air conditioners are turned on at the same time, electricity overload will occur. If the load current of the total power supply is too large, it will not be able to withstand such a large current.
Therefore, when installing a supermarket anti-theft device, the power wiring is very important. You must operate according to the engineer’s requirements. Do not design and install the electrical wiring yourself. When installing, pay attention to using an independent power supply. The power box uses two poles with grounding plugs to avoid As with other electrical appliances, the power socket used must be a two-pole grounded socket that meets safety standards. When all the connections have been connected, the installation and wiring must be checked repeatedly so that it can be powered on. When the supermarket anti-theft device is energized, if an abnormal phenomenon is found, the power supply must be cut off immediately, and then the power supply can be energized after troubleshooting. Power on and test for about 30 minutes to see if the system is normal before determining the installation location.
