The AN527 servo amplifier has been designed for controlled proportional-stroke valves with two magnet coils
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: command signal, valve current
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
