NRVF10 application field and working principle is widely used in the fields of communication, study and industrial production. It is a kind of variable frequency drive (VFD) which can effectively control the motor speed and torque. As an integrated electronic frequency converter, NRVF10 has been widely used in electric drive systems due to its advantages of high power, reliable performance and wide application range.NRVF10 belongs to a family of AC variable frequency drives and mains powered inverters, which can convert AC power from 50 Hz to 200 Hz frequency range. Its rated output voltage is from 0.75KV to 3KV, and its rated current range from 0.4A to 800A. Thanks to its user-friendly operation system, NRVF10 can be easily and simply controlled by a remote control or computer.The working principle of NRVF10 is based on the application of the power semiconductor switching device. Its basic working principle is to use high-speed switching operations to indirectly control the current passed through the motor. When the motor is running, the voltage and frequency output control signals produce a fixed frequency and amplitude modulation signal to the pulse width modulation circuit (PWM) of the variable frequency drive. Then, the correspondingly varies the width of the drive pulse signal to control the speed of the driven motor.NRVF10 has a variety of protection functions, such as over-current protection, over-voltage protection, and overload protection. It also offers a variety of signal control types, including airflow signal, torque signal and frequency signal. It is equipped with a self-adjusting two-stage acceleration and deceleration function, which is beneficial for optimizing the control of the motor`s speed and torque and improving the accuracy of the control system.Apart from the advantages mentioned above, NRVF10 has an excellent over-voltage, phase loss protection and over-current locking. It is also equipped with two power supplies of DC20V and AC220V. Furthermore, in terms of communication, NRVF10 supports the communication mode of six kinds of communication protocols (Modbus, Ethernet, Profibus-DP, CANBus, CanOpen, RS232, and RS485).To sum up, NRVF10 is a kind of advanced variable frequency drive with great advantages. Its application range and working principle make it suitable for many kinds of applications such as communication, study and industrial production. The powerful protection and control functions enable it to effectively and precisely control the speed and torque of the motor.
