Drive Frequency Converters

A frequency converter is a kind of power control device that controls the work of AC motors by changing their working frequency and is based on advanced frequency conversion and microelectronic technologies.

Main composition: The main components of a frequency converter are the rectifier-an AC-to-DC converter, filter, inverter-a DC-to-AC converter, braking unit, drive unit, detecting, and microprocessing unit. The inverter controls the internal IGBT for regulating voltage and frequency of the output power, which in turn provides the required power to the motor according to its demand. Thus, both energy saving and speed control can be achieved. Besides, frequency converters have a number of protective functions such as overcurrent, overvoltage, and overload protection. Along with the development of industrial automation, frequency converters find their wide applications in many industries today.

Features of the Product:

Original sensorless vector control algorithm, enhance low speed stability and improve the performance at low frequency.

It has fast response speed, with precision in speed and torque control, meeting the sudden load demands.

Advanced dead time compensation can effectively improve the low frequency torque, inhibit motor oscillation, optimize motor operation.

Optimized PWM control technology: The design is improved for electromagnetic compatibility. Excellent anti-trip performance provides suitability for high demanding grid conditions, temperature, humidity and dust environments. Robust and reliable hardware configuration can bear more overloads.
The varnish of high quality protects the modular hardware design for more protection and reliability.

The advanced identification method of the motor parameter improves the stability and precision of the system. Built-in PLC and PID controller; it offers automatic sleep/wake function while sustaining up to 16 sets of speeds. Input/ Output terminals can be flexibly replaced, while having as many as ten major and minor reference methods for setting the speed.
