The CAPVE-H economy connector amplifiers simplify control of proportional solenoids by supplying a current proportional to an input control of up to 5 VDC or 10 K potentiometer. The economy connector amplifiers accept power supply voltages from 9 to 32 VDC. The linear solenoid drivers utilize high frequency switching output (PWM) to provide a direct current (DC) output. 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 the economy version of the connector amplifiers there are no ramps. The units are available with a DIN 43650 connection to mount directly on the coil and comes complete with a 2m unterminated cable. Maximum current output is 1 or 2 A depending on the model.
