Overview

summaryThe frequency conversion control cabinet is mainly used to adjust the operating frequency of the equipment, reduce the energy loss, can start the equipment smoothly, and reduce the damage to the motor caused by the large current generated by the equipment when it is directly started. At the same time, it has its own analog input(for speed control or feedback signals), PID control, pump switching control(for constant pressure), communication function, macro function(with different parameter settings for diffe......

Product Details

Product details：

Variable frequency control cabinet products have overload, short circuit, lack of phase protection, leakage of pump body, motor overtemperature and leakage of electricity and other various protection functions and complete state display, and have a single pump and multi-pump control mode. Various main pump switching methods and various starting methods. The internal quality of the frequency conversion control cabinet is excellent, the appearance is beautiful and durable, and the installation and operation are convenient. It is a safe and reliable companion of various types of pumps.
Specifically applied to constant pressure water supply, fire inspection, sound-controlled fountains, air compressor, fan pumps, port machinery, machine tools, boilers, papermaking machinery, food machinery and so on.
Multiple control methods Control methods are as follows
1, liquid level control: according to the floating ball or electrode, the high and low liquid level changes from stop frequency conversion
Pressure control: the use of long-distance pressure gauge or pressure controller to measure the pressure of the pipe network, freely set the pressure of the pipe network, according to the actual water consumption to adjust the speed of the pump, so that it is always in an efficient state of operation
3, PLC control: frequency conversion input 4 ~ 20 mA or 0 ~ 10 V analog signal to give the output frequency
4, can achieve one control two, one control three and other control methods
5, more than one frequency converter can be used to achieve a number of control methods
Technical parameters
1, three-phase power supply: AC380V: 50HZ/60HZ ± 5 %;
2, control power supply: AC220V: 50HZ/60HZ ± 5 %;
3, allowed voltage fluctuation range: voltage constant fluctuation does not exceed ± 10 %, transient fluctuation does not exceed ± 15 %-± 10 %, voltage imbalance < 3 %, frequency ± 5 %;
