0-5VDC, 4-20mA or Pot Input, User Selectable Output
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.
