VPP3 – PWM Rotary Proportional Controller – Panel Mount
Description
VPP3 is a family of panel mount PWM controllers for proportional solenoid valves. Just mount it on the operator panel, connect power supply and proportional solenoid, then adjust the current using the potentiometer on board.
VPP3 is available for single solenoid and for double solenoid valves.

Features
- Adjustable minimum/maximum current for each directions (A+B);
- Adjustable rise/fall timeramp up to 25 seconds (step 0.1s);
- Adjustable PWM frequency from 50 to 300 Hz;
- Output curve shape: linear or parabolic (selectable);
- No. 2 multi purpose pins. Each one can be programmed to work as:
- Digital input (to enable or block outputs, speed selection).
- Digital output (dump valve, directional output, output over a threshold).
Factory Preset
- Min/max current: 500/1700 mA [ver. 12V] – 250/850 mA [ver. 24V]
- PWM frequency: 100 Hz
- OUT1 as DV output active when a PWM output is commanded
- OUT2 as FAULT output (positive = normal working);
- All working parameters are adjustable through a serial port and the Windows® SepSim program using a special serial port adapter (AISR).

Joysticks & Proportional ControllersPVPP2
Description
VPP2 electronic regulator is designed for single solenoid proportional valve open loop control. Current regulation potentiometer is connected and assembled yet on electronic regulator. Current range (offset and gain), ramps times and PWM frequency can be modified through trimming potentiometer (placed on the back side of card) to meet different kind of valves specifications. VPP2 is protected against supply over tension and polarity inversion.
