Power supply voltage requirements of Guangming Electric expansion door - replacement of electric expansion door in Guangming factory
Shenzhen Haifeng automatic door manufacturer´s expansion door is used in factories, units, warehouse rooms and other places. Its scientific name is stainless steel electric expansion door. Therefore, in its normal operation, the requirements of power supply are very strict, and the unstable expansion door of power supply must be like a mechanical dance, the continuous movement between shaking until the motor burns down. Haifeng told you that the electrical parameters of the electric expansion door should reach the rated voltage AC 220V, frequency 50Hz, power ≤ 1kW. Secondly, power supply line: power supply line within 50m ≥ 0.75, and power supply line above 50m ≥ 22.5. Invisible wires are actually hidden.
When the electric expansion door is running, the power supply voltage shall not be lower than 200V. When the voltage is lower than 200V, the stability of the stainless steel electric expansion door will be affected or it will not work normally. When the 380V power supply is connected wrongly or the zero line is in poor contact, the live line will form high voltage 380V and burn down the electrical products.
Therefore, Haifeng´s experience tells you that the electric expansion door is actually an electrical product. The joints of wires shall be handled properly. Pay attention to waterproof, prevent electric leakage and short circuit. Just like household appliances, we should take good care of them, protect them and clean them regularly. At the same time, in order to prevent electric shock and leakage and ensure safety, grounding wire is required. The ground wire can be buried at the end of the door truss, separately grounded or shared with the grid. The power plug on the table has a ground plug.
