Frequency Unit Converter, Frequency Voltage ratio has units of V/Hz, and is most commonly applied to the design of variable frequency motors or drives. Ever since Nikola Tesla and Westinghouse effectively won the AC/DC battle against Edison, alternating current has been in widespread use across the world for electrical power transmission. Not all equipment is designed for AC, and usually electronic devices need a DC (direct current) power supply which steps down the voltage, rectifies and regulates it. But most large electrical motors, including in domestic appliances, are designed to work with an AC supply, and for industrial motors this is usually three-phase.

1.Advanced vector control algorithm , combine accurate speed calculation and self learning of the motor parameter. It realize the accuracy control of motor speed and torque under no- speed sensor mode. V/F and SVC can be selected .

2.Optimized space voltage vector PWM modulation technology, has over-modulation function, high voltage-utilization, low output harmonic, and it greatly improves the motor's stability and switching loss.

3.Good operation characteristic of low frequency, can realize 0.5HZ/150% rated torque output which under no-speed sensor mode.

4.LCD and LED double display keyboard, display digit and English , the user can operate easily.

5.Control terminal analog voltage output, current output ,digit output, impulse output, Voltage, current , impulse , communication and other multi frequency setting modes. Also can realize the overplay function for all kinds of given source, And the frequency control mode is very flexible.

6.Abundant function:automatic voltage regulation control, automatic slip Compensation, restart when power cut  and so on. It can meet the demand of different clients.

7.Customization function design :program running, wobble frequency running, PID control operation , timing function ,counter function ect. can be convenient to form and  meet the  different industrial field demands
