0.25 ~ 22KW frequency converter series
1. Optimum matching design of frequency converter and motor
Integrating the most professional precision motor manufacturing technology and leading motor driving technology of the company, the full power and full load design ensures the best matching between the frequency converter and the driven motor, gives full play to the driving force of the motor, drives the motor reliably and safely, ensures the safe operation of the motor, and avoids the waste of money and power when the big horse pulls the small car and the small car matches the big horse.
2. Leading IGBT generation 4 variable frequency drive technology
Adopting the latest IGBT generation 4 softened on and off technology, DV / DT is very low even at high switching speed, reducing the high-order harmonic voltage generated by the frequency converter. The higher the voltage of high-order spectral wave, the greater the interference to the surrounding electrical equipment; The high-order harmonic voltage accelerates the insulation aging of the motor and shortens the service life of the motor; The higher harmonic voltage increases the leakage current of the motor to the ground, resulting in equipment leakage.
3. Ultra small volume
① A040 0.4KW size only: 72x131 × 107 (thickness)
② C300 3KW size only: 113 × one hundred and thirty-one × 139 (thickness)
③ At the same time, series a, B and C products all adopt the same height and size, which is convenient for users to arrange in the electric control box, convenient for wiring, neat and beautiful.
4. Super long life
The service life of electronic products has the greatest relationship with temperature. The design standard of safety regulations tells us that the service life of electronic products will be doubled every time the temperature is reduced by 10 degrees. Due to the leading IGBT generation 4 variable frequency drive technology, the switching loss and conduction loss of IGBT, the main heat source in the frequency converter, and the heating of the frequency converter are small. At the same time, with the overall aluminum alloy heat dissipation structure, the radiator is directly used as the base of the frequency converter and in direct contact with the air, The effective heat dissipation area is larger, the measured internal temperature of the frequency converter is reduced by more than 10 degrees, and the service life of the frequency converter is greatly improved.
5. Multiple motors operate in linkage, and the speed of each closing is fine tuned
The dual-mode analog input and patented function operation can simultaneously raise and lower the speed of the multi combination motor through the external speed regulating potentiometer, set the function E and F values according to the production needs, and fine tune the speed of each motor independently to meet the production process requirements. (a, B and C series frequency converters do not have this function)
6. Easy to drive electromagnetic brake motor
As the electromagnetic braking motor has strict requirements on the control timing, if the user's design timing is unreasonable, it is very easy to damage the motor or frequency converter. The special control port and menu for the electromagnetic braking motor are built in, so the user can control the electromagnetic braking motor without complex debugging and avoid complex debugging and risks.
7. PLC 0-1khz high speed pulse speed regulation function
The analog output of PLC can be controlled by the high-speed converter, but the cost of PLC is not high. The analog output of PLC is generally high, but the standard output of PLC is not large. Therefore, the cost of PLC is low. The main engine has the standard output of 1kHz, but it is not convenient for users to purchase the standard output of PLC
PLC control of frequency converter.
8. Isolated RS-485 communication and menu setting software
The whole series of products are equipped with isolated RS-485 communication and Modbus protocol as standard to meet the bus application. The isolated design has high reliability and meets the requirements of industrial strong interference and harsh environment. Equipped with computer menu setting software, users can use the computer to modify the frequency converter menu and download the setting menu in batch, so as to improve efficiency and facilitate debugging.
9. Humanized user-defined display, convenient and intuitive speed regulation
The traditional frequency converter speed regulation only displays the output frequency, but users do not need to know the output frequency at all. What they need to know is the corresponding process parameters, such as the speed of conveyor belt 835.8mm/s. Humanized user-defined display can meet the intuitive and practical display needs of users.
10. Equipped with DF48, DF50 digital display panel
The traditional frequency converter adopts the pull-out screen design, that is, the frequency converter menu setting control panel is removed and installed on the equipment electric control box for users to operate and use. Because the control panel has the menu setting function, it is very easy to cause users to misoperate and modify the menu, resulting in equipment human failure and increasing the after-sales service cost of equipment manufacturers. At the same time, there are too many buttons on the panel that users can't use, and the training management of users' staff is complex. DF48 and DF50 digital display panels specially tailored for user operation are more practical and convenient.
