Kesla VPP3 Proportional PWM Flow Regulator One Way

VPP3 Proportional PWM Flow Regulator One Way Controller Max 2.5A
Proportional controller PWM panel mount for single solenoid valves.

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.

Properties:

- adjustable PWM frequency from 50 to 300 Hz;

- adjustable minimum/maximum current for each directions (A+B);

- adjustable rise/fall timeramp up to 25 seconds (step 0.1s);

- 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).

--------------------------------------------------------

The regulator VPP3 is designed to command directly one or two proportional solenoid valves.

The reference signal is taken from the potentiometer and converted to a low frequency power PWM command.

The current through the solenoid is read in feedback in order to keep

The reference signal is taken from the potentiometer and converted to a low frequency power PWM command. The current through the solenoid is read in feedback in order to keep it stable regardless of the temperature and supply voltage changes. The frequency of the PWM outputs is adjustable. To get best performances it should be set accordingly with the specifications of the manufacturer of the hydraulic valves. The electronic card is protected against short-circuits of the load. In case of supply reversal a power diode inside the device short circuits the power supply. This causes the intervention of the external fuse that must be installed. VPP3 are prepared with two different settings for 12V and 24V generic hydraulic valves. A more precise settings of the current range will result in improved control sensitivity over the entire control range. Fall and rise timeramps are preset to zero. Setting changes and advanced programming can be done using a PC with serial port, using the SepSim Windows® program and the special serial port adapter with M8 connector. A multicolor LED under the mounting panel is lit green when joystick is supplied and gives information on the status of the device with a sequence of colored flashes.
