FACTS ABOUT VFD CONTROL PANEL REVEALED

Facts About VFD control panel Revealed

But, if we lessen the frequency to 30Hz, then we have to also decrease the voltage to 240V as a way to keep the V/Hz ratio. How are we gonna reduce the voltage if the only real voltage We now have is 650VDC?This known as Pulse Width Modulation or PWM. Visualize that we could control the stress in a very water line by turning the valve on and off in
