Variable Frequency Drives

A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.

25kw 3 Phase AC 380V Variable Frequency Drive Inverter Bangzhao pure sine wave series inverter is one of the most advanced DC to AC conversion products in the world, it has the main advantages of high quality sine wave AC output, microcomputer control, humanness design, and it is simple, stable, no noise and no pollution. It is suitable use for areas without electricity, vehicles, ships, solar energy, wind turbine etc. The inverter can also supply AC voltage to all kinds of power tools, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other power supply. The inverter output waveform is pure sine wave; this kind of AC power is suitable for most industrial electronics and home appliances, the power supply features much better than other modified sine wave and square wave. Technical Features:   * Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It's service life can up to 15 years or more. *Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter's usage, which reduced the cost of equipment investment, easy to connect wires and control. * Pure sine wave output with good transient response, little harmonic distortion, higher conversion efficiency and stable output voltage features. *Adopted low frequency isolated transformer, high conversion efficiency and stable performance * Output AC Power is suitable for all types of home appliances, electric tools, electric motors etc. * Converter has the function of filtering the grid disturbance and interference at the same time, which is a good performance of stabilized voltage and frequency power, to provide a more stable and pure power supply environment for the backend devices * Safety and reliable, the input single-phase electric and output three phase electric is complete electrical isolated. * Pure sine wave output, has higher efficiency and higher capability of driving load. *Output perfect protection function, with output over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection * Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display. * The input voltage, output voltage, frequency and phase can be custom made.
