1. First check your own motor power, and select the inverter power according to the motor power. Generally, it is recommended that the inverter power is greater than the motor power.

2. Next, confirm that the inverter you purchased is the national standard power. The recommended purchase price is at least medium. The low price is basically virtual standard power. All electrical products are configured according to power, and insufficient power is easy to cause unnecessary losses.

3. Then confirm according to the load and environment of the motor. In case of water supply and sewage load, and in areas without altitude, the frequency converter only needs one power higher than the motor; If it is a crusher. The specific power of the frequency converter shall be determined according to the starting time, starting current and altitude of the motor.

4. The frequency converter is attached. Generally, the frequency converter needs to be used with pressure gauge, float ball and other equipment. Confirm whether the above equipment is included when purchasing.

5. Finally, make sure that your frequency converter needs to carry multiple motors at the same time to confirm the control mode of the frequency converter. Whether it is one to control one or one to control two or more spaces, at present, one to control six frequency conversion cabinets is realized in China.

On the market, the water supply frequency converter below 22KW is a negative frequency converter, which is easy to install and can be carried directly on the pump. There is no requirement for the environment. It is conventional and rainproof, and can be customized. Generally, the machinery adopts universal frequency converter, which can be stand-alone and boxed. The boxed can be directly installed on the cabinet door, real-time display and convenient operation.

The above are precautions when selecting frequency converter. Of course, many details are not reflected in the article. If you are interested, you can contact our technicians. Tel: 0086-400-138-3099
