    Common sense of power supply: 1. The output voltage of the power converter needs to be equal to the input voltage of the electric equipment or the input voltage range marked by the electrical equipment.
    2. The output current of the power converter is the maximum current that the converter can output, and the actual output current is decided by the electric equipment.
    3, when purchasing power supply for the equipment, the peak power of the load equipment should be configured, rather than the common rated power.
    4, different load types, the peak power and its rated power ratio is different. Such as motor, its starting peak current is generally 4-8 times the rated power, the minimum need to choose 2-3 times the rated power of the product.
    5. The use of wires should meet the maximum current required to pass through the power converter. With 8-40V to 24V6A converter as an example, the maximum input current is calculated as: 24Vx6Ax1.17 (conversion overload protection point +7% 110% loss), 8V (minimum working voltage) =21.06A, should use 2.5mm2Copper cored wire
    6, copper wire carrying capacity of wire safe carrying capacity is based on the allowed core temperature, cooling conditions and installation conditions to determine the. General copper wire safety 5~8A/mm2The safe carrying capacity of aluminum conductor, 3~5A/mm2
    7, please accurately calculate the load power, in order to make the equipment to achieve the best use of the state, it is recommended not to exceed the power product marked power of 80% load, do not overload.
    8, about vehicle voltage: at present, gasoline vehicles generally use 12V power, heavy diesel vehicles use 24V power.
    9, because the battery discharge capacity is limited, in the opening of high-power load moment, the battery high current discharge will cause the battery output voltage greatly reduced
    Friendship tips: 1, please accurately calculate the load power, in order to make the equipment to achieve the best use of the state, it is recommended not to exceed the power product marked power of 80% load, do not overload. If you have any questions, please consult technical clothing.
