CAPV-H-5V-x: Connector Amplifier For Proportional Valves

The Connector Amplifier simplifies control of proportional solenoids by supplying a current proportional to an input control (0-5V or 0-20mA or 10K potentiometer or pre-set level). It accepts power supply voltages from 9 to 28VDC. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output. The options for current output include 2A, 1.2A, 800mA or 600mA. A current sensing circuit maintains output current regardless of changes in input voltage and coil resistance. The user can adjust maximum and minimum current, ramp times, dither frequency, and amplitude to match the application. The unit is available with a DIN 43650 connection to mount directly on the coil. Other versions are available with 4-20mA or 0-10V inputs. A remote mount version is housed in a rugged metal box.


  • Simple control with a potentiometer or sophisticated control with 0-5 VDC or 0-20 mA signal inputs
  • Broad range of supply voltages (9 to 28 VDC) with no degradation in performance
  • IP65 weather resistance rating
  • Current sensing circuit maintains output regardless of changes in input voltage or coil resistance
  • Modern technology utilizing high frequency switching output (PWM)
  • Energy efficient design (no heat sink is required)
  • Ramp settings are independent
  • Simple implementation of “soft shift” control with minimal external components
  • Mates to a DIN 43650 plug on a cartridge or block style solenoid valve
  • Reverse polarity protection
  • CE certified for EMC
