SVF12-3,81 is a high-quality air-oriented, non-inversion variable frequency drive series synthesized by modern power electronics technology and the latest vector control technology. It is a power conversion device which can realize the coordinate control of the speed, line and time of various operations. It is widely used in manufacturing, mining, lifting, machine tools, fan (ventilation) and power generation.

SVF series products have started to form a complete product line, from 0.75KW to 2.2KW. The whole series of products use the latest IGBT module power device, and the advanced vector control technology makes the speed control range wider, faster dynamic response, high torque output capacity, and the power management function of the whole machine is stronger, more reliable and more energy-efficient.

The application field and working principle of SVF12-3,81 is numerous, as it can be seen deployed in a variety of industries as a crucial component to achieving production. But the working principle is basically the same in all its fields of application: First, the input signal from the control device is sent to the drive controller; after the power device of the drive is powered up, the signal is amplified and converted into a PWM (pulse width modulation) signal by the microcontroller of the drive controller; then, the PWM signal is output to the power device and the power device changes it into an analog voltage; finally, the analog voltage is used to power the motor. This power fluctuates with the PWM signal\'s frequency, and the faster the frequency of the PWM, the higher the voltage.

The primary function of the SVF12-3,81 variable frequency drive, is to convert the low frequency and low volts of AC power outputted from the industrial power system into high frequency and high volts PWM power which can drive a motor very efficiently. The frequency and voltage of the PWM will be automatically adjusted according to the actual demand of the motor\'s speed and torque. By varying the frequency and voltage, the device\'s output power can be more accurately and precisely controlled, which has become the preferred choice for industrial use.

Other than providing excellent energy-saving potential, SVF12-3,81 variable frequency drives feature high speed dynamic control, as well as smoother torque control due to their vector control functions. In addition, many accessories, such as braking resistors, can be added to its system so that its performance and usefulness can be further optimized, which makes it a desirable choice for many industries.

To summarize, the SVF12-3,81 series variable frequency drives are truly an ideal product for using in industrial applications. Its efficient energy-saving and precise torque and speed control features make it an invaluable component in many industries. With the latest and advanced IGBT module power devices, one can rest assured of a reliable and long-lasting performance due to its strong power management.
