Variable frequency controller:
Function：
(1)Prevent the motor from starting instantaneously, and the current will double and increase; after installing the inverter, the motor will start .The instantaneous current will not increase suddenly, which not only saves cost, but also makes the electrode life longer.
(2)Motor speed regulation, by changing the frequency, the motor speed can be controlled.
(3)The variable frequency driver can be used with water pump in the intelligent agricultural irrigation and coagulation system, which can control the pressure and flow rate of the water pump.
Customized：
1.One control one (control one water pump)
There is a total of a water pump on site. The PD value fed back by the pressure gauge or transmitter is compared with the set pressure. When the system pressure reaches the set pressure, the frequency will be reduced, sleep, and standby. When the system pressure is lower than the set value or wake up Frequency conversion and frequency under pressure
2.One use one preparation
The two pumps are standby pumps for each other, and can work alternately according to the set procedure, and only one pump works.
3.One control two (pressure assist) (control two pumps)
A total of two pumps refers to a total of two pumps on site, one works online, and two pumps can work online at the same time. For example, if the pressure of the No. 1 pump is insufficient for a period of time, it will automatically start the No. 2 pump to assist in boosting.
4.It can be customized with rich combination functions such as one control two, one control three, one control four, one control five, etc., as well as power frequency conversion and constant pressure water supply.
water pump：
Functions：
(1)High lift, large flow, intelligent finishing, full power, long service life, low temperature rise and high efficiency.
(2)Variable frequency self suction pump, intelligent micro control, large water output, long-lasting work, widely used, compact structure, strong shock proof.
Application：
Irrigation inverter controller can be widely used in hotels, farmland irrigation, fire water, domestic water, waterworks, construction sites and other environments.
