Application
1: The hard start of the motor will cause serious impact on the power grid, but also the capacity of the power grid is too high, the large current and vibration generated during the start of the baffle and valve is greatly damaged, and the service life of the equipment and pipeline is extremely unfavorable. After the use of frequency conversion energy-saving device, the soft starting function of frequency converter will make the starting current start from zero, the maximum value will not exceed the rated current, reduce the impact on the power grid and the requirements of power supply capacity, prolong the service life of equipment and valves. The maintenance cost of the equipment is saved.
2: Theoretically speaking, frequency converter can be used in all mechanical equipment with motor, motor at start, the current will be 5-6 times higher than the rated, not only will affect the service life of the motor and consume more electricity. In the design of the system, there will be a certain margin in the motor selection, the speed of the motor is fixed, but in the actual use process, sometimes to run at a lower or higher speed, so it is very necessary to carry out conversion transformation. The inverter can realize the soft start of the motor and compensate the power factor.

FAQ
Q: Do you supply pattern ? Is it free?
A: If the pattern is low value, we will grant the free pattern with freight collect. But for some excessive fee samples, we want to gather the pattern charge.
Q: What is your time period of payment?
A: 30% down charge earlier than producing and 70% stability charge earlier than shipping.
