3 phase frequency inverter


variable frequency inverter

220V ~ 240V AC Frequency Inverter Overload 0.4KW ~ 185KW


VFD frequency converter is a general-purpose high-performance frequency converter, mainly used to control and regulate the speed and torque of three-phase asynchronous motor. It adopts high-performance current control technology, low frequency and high torque output, strong overload capability and superior stability. Sexual and dynamic performance, with a variety of communication bus functions, support for multiple PG cards, powerful, stable performance; with perfect anti-skip control and ability to adapt to poor grid, can be widely used in textile, paper, wire drawing, machine tools, packaging Drive changes in food, fans, pumps and various automated production equipment.
