VFD control panel

With the frequency technology become more and more mature, the use of frequency converter, PLC, digital-analog conversion module, temperature sensor, temperature module and other devices combine to form a closed-loop automatic temperature control system, the system can work smoothly and more importantly, Its energy-saving effect of up to 30% or more, can bring good economic benefits.

The frequency convert panel adopts the enclosed cabinet structure, adopts the frame skeleton, the surface coating spray, and easy to install the cabinet, the upper end may dispose the main line, the frequency converter panel leads to the cabinet outward appearance to be possible to operate directly, according to demands may establish the local and long-distance Control or PC / PLC communication control, with a very intuitive variety of display functions. Frequency converter is a dedicated accessory products, the frequency’s function of control speed and the main technical parameters depends on the inverter’s built-in specifications and external configuration. Frequency inverter cabinet has great differences according to different usages and different functions. according to the needs of the operating conditions can be installed AC input reactor, output reactor, DC reactor, EMI filter, braking unit, breaking resistor, contactor, intermediate relay, thermal relay, PLC, GOT , watt-hour meter, cooling fan, etc., According to the system working conditions, to set a variety of control buttons and indicators such as forward, reverse, motor speed boost, motor speed deceleration, jog forward, jog reverse, manual / automatic, emergency stop, frequency conversion, power frequency, PLC control, touch screen and so on.



Frequency converter control panel function
the power switch and protection frequency converter panel are equipped with low-voltage MCCB which is connected to the power line, in addition to complete and disconnect the circuit, and also against short-circuit, overload protection, cut off the power during maintenance.

Set frequency start, frequency stop button on start-stop control function frequency conversion panel for the inverter operation control, convenient to operate at site.
n, cut off the power during maintenance.

Set frequency adjustment potentiometer on frequency (speed) adjustment Frequency converter panel, you can easily manually adjust the inverter’s output frequency to control the motor speed
during maintenance.

The table shows the voltage meter, ammeter, frequency meter and various indicators such as power indication, alarm indication, operation instruction and power frequency indication on the inverter cabinet panel, and realize the input voltage, output current, output frequency and various work of the inverter State monitoring.

Standby frequency switching Users can choose frequency panel which have the standby power frequency switching, when the inverter fails, the motor through the automatic control circuit to switch to power frequency power (this method can choose manual / automatic, if frequency starting device greater than 15KW, use soft starter)

A variety of control functions can be set according to system conditions on the inverter cabinet panel, through setting a variety of control buttons and indicators such as forward, reverse, motor speed, motor deceleration, jog forward, jog reverse, manual / automatic, Emergency stop, frequency / frequency, PLC control, touch screen and so on

Installation of external equipment according to the needs of the operating conditions can be installed in the inverter cabinet, including AC input reactor, the output reactor, DC reactor and EMI filter, braking unit, braking resistor, contactors, intermediate relays, thermal relay, programmable Controller (PLC), man-machine interface (HMI), watt-hour meter, cooling fan etc.

Safety protection Install the VFD in the frequency control panel, can reduce environmental pollution, reduce the risk of electric shock, will have better protective effect.

Characteristics Analysis

save energy:

Inverter control motor Compared with the traditional control of the motor, energy conservation is the most practical significance, according to the demand for electrical equipment to supply the operating conditions of the economy is running, you can achieve energy-saving effect.

Lower operating costs:
The operating cost of a conventional motor consists of three components: initial purchase cost, maintenance cost, and energy cost. Energy costs account for about 77% of the motor's operating costs. Through energy costs can be reduced by 44.3%, coupled with the frequency of the impact of the device after the start to reduce maintenance and repair volume also decreased, so the operating costs will be greatly reduced.

extend motor’s life:
Starting from 0HZ, the start-up time can be adjusted to reduce the impact on the electrical components and mechanical parts of the motor at start-up, thus enhancing the reliability of the system and prolonging the service life of the motor. In addition, the frequency conversion control can reduce the unit start when the current fluctuation, this fluctuation current will affect the power grid and other equipment, the inverter can effectively reduce the peak starting current to a minimum.

reduce motor’s noise
According to the requirements of the motor operating conditions, the installation of frequency control, the motor speed significantly slowed down, so effectively reduce the motor running at the end of the noise.
uation, this fluctuation current will affect the power grid and other equipment, the inverter can effectively reduce the peak starting current to a minimum.

Applicable Industry
The frequency converter control panel (frequency changer electric control panel / electrical control panel) may widely apply in metallurgy, chemical industry, petroleum, water supply, mine, building material, electrical machinery profession pumps and so on, air compressor, rolling mill, transport aircraft and other machinery and equipments.
