Variable-frequency Drive (VFD) is an electric power control equipment that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the working power supply of the motor. The inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to communication), braking unit, drive unit, detection unit and microprocessor unit. The inverter relies on the internal IGBT to adjust the voltage and frequency of the output power supply, according to the actual demand of the motor to supply the power supply voltage it needs, so as to achieve the purpose of energy saving and speed regulation, in addition, Delixi inverter has a lot of maintenance functions, such as overcurrent, overvoltage, overload maintenance and so on. With the continuous improvement of industrial automation, Delixi inverter has also been 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. Freshman specs are also OK.
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 resistor should be selected at the same time.
4. Check the rated current of the nameplate of the motor, (the rated current is measured when there is no nameplate).

The difference between air switch and leakage protection switch - Delixi
(1) The function is different.
An air switch is a kind of circuit breaker that maintains "something", which can maintain the safety of the entire household wiring and appliances, and avoid the overheating and burning of the wires.
The leakage maintenance switch is a kind of circuit breaker for maintenance personnel, which can block the circuit in time when leakage is carried out to avoid the danger of electric shock.
