3-400V refers to the voltage range, which is used to describe the rated voltage of electrical equipment or power lines. Among them, 3V to 400V is the commonly used rated voltage range in power systems and household appliances, used to drive various electrical equipment and household appliances.
In industrial production, 3-400V is an important voltage range. Low-voltage equipment usually uses DC power with a voltage level of 3-50V, such as computers, computers, radios, etc. These equipment use DC power supplies, which can well ensure the stability and reliability of their work. High-voltage equipment generally uses alternating current, with a voltage level of 400V and above, such as large motors, generators, transformers and other high-power equipment.
In family life, the voltage range of 3-400V is also common. Some commonly used household appliances such as TVs, washing machines, refrigerators, etc. have their rated voltage levels within this range. Inside. In addition, with the continuous advancement of science and technology and the rise of renewable energy sources such as solar energy and wind power, there are still higher and lower requirements for the voltage range of equipment. This requires power engineers to carefully design and optimize equipment performance to achieve better performance. Well adapted to market and user needs.
This value is not high pressure.
High voltage refers to the voltage level higher than 110 kilovolts (kV) in the power system, and 160 megawatts (MW) of electricity belongs to the medium voltage and low voltage range.
Megawatt is a unit of power in the International System of Units, used to express the output power of large generators, wind turbines and hydroelectric generators.
