Variable-frequency drive (VFD) is an electric power control device that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the power supply for motor operation. The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to communication), braking unit, drive unit, detection unit and microprocessor unit. Inverter by the internal IGBT interrupting to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, and then to achieve the intention of energy saving, speed regulation, in addition, Delixi inverter also has many maintenance functions, such as overcurrent, overvoltage, overload maintenance and so on. With the continuous improvement of industrial automation, Delixi inverter has also been very widely used.
1. Delixi inverter power is selected according to the load power. Choose a frequency converter with a large power for a motor with a high power of the motor. The freshman standard is also possible.
2. Different types of inverters are used to choose different Delixi inverters. For example, there are universal Delixi inverters, there are fans and pumps dedicated to Delixi inverters, there are machine tool spindles dedicated to Delixi inverters and so on.
3. If the load inertia is large, the braking unit and braking resistance should be selected together.
4. Check the rated current of the nameplate of the motor, (the rated current is measured when there is no nameplate).

Switching power supply FAQ - Delixi
1. The safety wire is blown off
In a general environment, a blown safety wire indicates that there is a problem with the internal wiring of the power supply. Because the power supply is operated in the shape of high voltage and high current, the fluctuation of the grid voltage and the surge city cause the current in the power supply to increase suddenly and cause the safety wire to be blown off. The focus should be on checking the power ...
