CAPVE-H-5V-xA-5C-2M: Connector Amplifier For Proportional Valves

The Economy Amplifier simplifies control of proportional solenoids by supplying a current proportional to an input control (0-5 VDC or 10K potentiometer). It accepts power supply voltages from 9 to 32 VDC. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output. Maximum current output is 2 Amps (1 Amp version available). A current sensing circuit maintains output current regardless of changes in input voltage and coil resistance. The user can adjust maximum and minimum current to suit the application. Dither frequency and amplitude are factory set. In this economy version of the connector amplifier there are no ramps. The unit is available with a DIN 43650 connection to mount directly on the coil and comes complete with a 2 meter unterminated cable.


  • Simple control with a 10K potentiometer or sophisticated control with 0-5 VDC control signal input
  • Maximum current output of 2 Amps (1 Amp model available)
  • Mates to a DIN 43650 plug on a cartridge or block style solenoid valve
  • Broad range of supply voltages (9 to 32 VDC) with no degradation in performance
  • Current sensing circuit maintains output regardless of changes in input voltage or coil resistance
  • Modern technology utilizing high frequency switching output (PWM)
  • IP65 weather resistance rating
  • Energy efficient design (no heat sink is required)
  • Electronic limiting circuit means no internal fuses
  • Short circuit proof (in case of solenoid failure or mis-wiring)
  • Reverse polarity protection
  • CE certified
