UNT-VFD Low Voltage Inverter

Views:

Product Overview:
The frequency converter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, microprocessor unit of detection unit and so on. Frequency converter adjusts the voltage and frequency of output power supply by the interruption of internal IGBT, and provides the required power supply voltage according to the actual needs of motor, so as to achieve the purpose of energy saving and speed regulation. In addition, frequency converter also has many protective functions, such as over-current, over-voltage, over-load, over-heat protection and so on. With the continuous improvement of industrial automation, frequency converter has been widely used.

UNT-VFD series frequency converter is a high performance universal frequency converter, which is mainly used to control and adjust the speed of three-phase AC asynchronous motor. With high performance vector control technology, low speed and high torque output, it has good dynamic characteristics, super overload capability, user programmable function and background monitoring software, communication bus function, support for a variety of PG cards and so on. The combination function is rich, powerful and stable. It can be used to drive textile, paper-making, wire drawing, machine tools, packaging, food, fan, water pump and various automatic production equipment.

Product characteristics:

Wide range of applications, a variety of control methods, open-loop vector control (SVC), closed-loop vector control (FVC), VF control;

16-stage speed, simple PLC and PID control;

Support multiple motor vector control;

High starting torque characteristics;
