The VPP2 electronic regulator is made for controlling single solenoid proportional valves using an open-loop system.

Control is achieved via a front mounted Potentiometer

You can adjust:

• Current range (both the starting point and maximum)
• Ramp times
• PWM frequency
  All of these can be changed using the adjustment knobs located on the back of the device, so it can work with different types of valves.

Safety Features:

• Protected against too much input voltage and reversed power connections.
• The PWM output is protected in case of a short circuit.
• The circuit board is sealed with epoxy resin for extra protection.

Installation:

Mount the regulator to a panel using the two included M4x10 countersunk screws.
A diagram shows the front panel size and where to drill the holes.

It comes with a sticker marked from 0 to 10.

You can place this next to the adjustment knob to easily see and remember your settings.
