Frequency conversion power supply selection and installation instructions
Driven by scientific and technological research and development, the precision of industrial equipment and industrial instruments continues to improve, and the corresponding industrial equipment’s requirements for energy supply such as power supply have gradually increased. In this context, variable frequency power supply, 60HZ variable frequency power supply, 400HZ intermediate frequency power supply, and single-phase variable frequency power supply that can provide stable current for equipment are welcomed by the market. In order to ensure the operation and life of precision equipment, many enterprises have purchased variable frequency power supplies and single-phase variable frequency power supplies.
In the current market, there are many products of variable frequency power supply and single-phase variable frequency power supply, and the performance is also different. When choosing variable frequency power supply, manufacturers must pay attention to the input power supply voltage, frequency, output power, load characteristics and so on. In addition, manufacturers also need to take into account the matching degree of frequency conversion power supply and the corresponding motor, in order to give full play to the energy-saving advantages and stability advantages of frequency conversion power supply and single-phase frequency conversion power supply to ensure the operating condition of the equipment.
After choosing frequency conversion power supply and single-phase frequency conversion power supply, manufacturers should also pay attention to the installation of frequency conversion power supply and single-phase frequency conversion power supply. The installation environment of variable frequency power supply and single phase variable frequency power supply must be as clean and dust-free as possible, and have a good ventilation and heat dissipation environment. If conditions are available, the ventilation mode of roof exhaust air intake at the bottom of the wall side can be considered. When installing variable frequency power supply and single phase variable frequency power supply, the top and side of the variable frequency power supply must be left with a minimum heat dissipation distance to facilitate the heat dissipation of variable frequency power supply. In addition, when installing the inverter power supply, it is also necessary to avoid the area with increased humidity. Because if the humidity is too large, the electrical insulation of the inverter power supply itself will be reduced, generally maintained at 40%-90%.
