AC Drivers-Universal Frequency Inverters (VFD-F520 Type)

Product Description

VFD-F520 type frequency inverter (AC Drivers) is an universal 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.
