Amplifiers for proportional valves for adjusting the flow of axial piston<br />
pumps<br />
< Analogue amplifiers of Euro-card format for installation in 19" racks<br />
< Voltage stabilization with raised measuring zero point, filter capacitor on the amplifier card<br />
< Differential input<br />
< Internal command value adjustment by means of 4 trimming potentiometers, call-up via<br />
relays, on some versions LED indicator lamp<br />
< Ramp generator<br />
< Ramp times can be adjusted by means of trimming potentiometers (on some versions<br />
separately for up/down)<br />
< Oscillator/demodulator for inductive transducer (on some versions)<br />
< PID-controller for controlling the swivel angle (on some versions)<br />
< Cable break detection with LED indicator lamp for swivel angle transducer; in the event of<br />
a cable break, the output amplifier is de-energized (on some versions)<br />
< Clocked output amplifier with current regulation<br />
