For security considerations, frequency conversion power supply, 60Hz power supply, 400 Hz power supply, frequency conversion voltage regulatory power supply, and other products need to pay attention to the following points, because the environmental installation of the inverter power supply is straightforward and its service life is straight Impact. The importance of the inverter power supply should pay attention to the following points: 1, the speed is good, the efficiency is high. At low speed, the static level rate is high, and the relative stability is good.

2, the use of the inverter use ambient temperature is generally suitable at -10 ¡ã C ~ 40 ¡ã C, humidity in environmental work below 90. If the ambient temperature is higher than 40 ¡ã C, each liter is 1 ¡ã C, the inverter should be reduced by 5. The ambient temperature is 10 ¡ã C per liter, and the inverter has a long life, so the problem of surrounding ambient temperature and inverter heat dissipation must be handled.

3, all power products such as variable frequency transformer power supply, transformer voltage, etc. should be kept from fire and high temperature to prevent temperature too high. 4, alert fuel, salt to the erosion of variable frequency power supply.

5, place the variable frequency power supply in a good ventilation, at least 30 cm from other objects around it to keep the ventilation ventilation. 6, the normal operating environment of the variable frequency power supply is 0 ¡ã C ~ 40 ¡ã C, the humidity of 0 to 90% (non-condensation state) 7, preventing the variable frequency power supply from being included in the corrosive gas and vibration, magnetic field interference. 8 to prevent the converted power supply from being placed in direct sunlight, rain or moisture.

9. Do not place 60 Hz power, 400 Hz power and other various power products in uneven or tilt. 10, when the inverter drives standard motors, and compared with the power frequency power supply, the loss will increase, and the effect is deteriorated when the low speed is resistant, and the temperature rise of the motor will increase.

Therefore, the load torque of the motor should be reduced at low .
