The RunnTech P9000 Proportional Amplifier is used with hydraulic proportional valves. It has an adjustable output current and flutter amplitude, protection from overcurrent and short circuits, and controls output current based on an external 0-10V or 0-15V signal. It operates from a 20-32VDC power supply and has adjustable rise and fall times from 0.1-10 seconds.
