AC Drivers-High Power Frequency Inverters (VFD-E Type)

Product Description

VFD-E type high power frequency inverter (AC Drivres)is a high power model adopting space voltage vector+random PWM as core control mode, which is widely used to adjust the rotating speed of a motor-driven system, such as pumps, fans, light industrial machine, and water supply system in constant pressure.
