VPP3 is a family of panel mount PWM controllers for proportional solenoid valves. 0-5V, 0-10V, 5-0-5V, 0.5-2.5-4.5V or any other range within 0-10V, Ratio-metric 25 – 50 – 75% of supply voltage Just mount it on the operator panel, connect power supply and proportional solenoid, then adjust the current using the potentiometer on board. VPP3 … Continue reading VPP3 Direct Drive Potentiometer PWM
