Digital card for pressure/flow control control in closed ring systems for pressure/flow P/Q.Ge control for circuits with high -dynamic valve with null -root cover and hydraulic actuator equipped with analogue pressure sensors. The controller automatically commutes from control in flow to pressure to maintain the pressure within the set limits. The closed pressure ring is active only with positive range command.  The output value to control the voltage or current valve must be configured via software. The EWMPC/20 software can be downloaded from this page. Connection with USB port on the front. The start -up manual is available for our customers after obtaining credentials for access to the reserved area.
