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.
