The amplifier AN528 was developed to control proportional valves in a closed-loop control
Secured against wrong polarity
Secure of short-circuit
External switch-off ramp
Ramp with quadrant identification
Wide range of ramp adjustment
External enable (no-load current circuit)
Test jack for: desired value, valve current, displacement pick-up signal
Same potential of: minus of the supply voltage zero-potential of the inputs zero-potential of the reference voltage
PWM - output stages (high dynamic)
4 different inputs for the most popular input-voltages and -currents, allows very flexible input switching
LED indication for: Power on, Ramp off, Fail safe
Potentiometer for: Ramp time, Zero overlapping, gain
