Flow Pressure Curve

There are two speed regulation modes: PWM and 0-5V.
PWM speed regulation: 10KHZ ~ 30KHZ, amplitude: 5V, the control ratio is 0-10% without rotation, and the speed regulation range is 11%-100%.
Analog voltage speed regulation: voltage 0-5V, 0-0.5V motor does not rotate, 0.6-4.5V speed regulation range.
Yellow line speed feedback, connect to oscilloscope probe or host computer. 1 pulse/revolution speed (revolution/min)=FG signal*60
Running at full speed: positive to red and white; negative to black
Substitute blue wire for white.
NO fittings included
