| General description | |
| This module is used for the control of proportional valves with one or two solenoids. Various adjustable parameters enable an optimized adaptation to the respective valve. This power amplifier is inexpensive and a space-saving solution. The amplifier is controlled by different voltages or current input signals. The output current is closed loop controlled and therefore independent from the supply voltage and the solenoid resistence. Ramps, MIN and MAX and PWM-frequency are adjustable via potentiometer. |
