First, it is a fan/pump load

Second, the device itself has a power-saving function (software support)

Third, we need to work for a long time

The above are the three conditions that reflect the results of power saving. If it is said that the power frequency of the inverter is energy-saving without conditions, it is important or trade speculation. Knowing the reason, you will magically manipulate it for you. It is necessary to pay attention to the place of use and the conditions of use to use it accurately, otherwise it is.

Power factor compensation saves energy

Reactive power not only adds line loss and equipment fever, but also leads to the decline of power factor in the active power of the power grid.

After the use of frequency conversion speed regulation device, due to the infection of the filter capacitor inside the frequency converter, the reactive power loss is reduced and the active power of the power grid is added.

Soft engine energy saving

The hard start of the motor has a severe impact on the power grid, and the requirements for the capacity of the power grid are too high, and the large current and sensation that occur when the motor is started are extremely harmful to the baffle and valve, and the service life of the equipment and pipes is extremely unlucky.

After the use of frequency conversion energy-saving device, the soft start energy of the operation inverter will make the starting current start from zero, and the maximum value will not exceed the rated current, which can reduce the impact on the power grid and the requirements for power supply capacity, delay the service life of equipment and valves, and save the cost of equipment.

Theoretically, frequency inverters can be used in all mechanical devices with electric motors. When the motor is started, the current will be 5-6 times higher than the rating, which will not only affect the service life of the motor, but also consume more power. The speed of the motor is fixed, but in the actual application process, sometimes it is necessary to work at a lower or higher speed, so it is often necessary to carry out frequency conversion.
