<strong>AN527</strong> <strong>Servo</strong> <strong>Amplifier</strong><br />
<strong>COMPONENTS</strong><br />
The <strong>AN527</strong> servo amplifier has been designed for controlled proportional-stroke<br />
valves with two magnet coils.<br />
The <strong>AN527</strong> is only used to control proportional valves. Therefore, as this board is not only an<br />
amplifier for controlled valves (<strong>AN527</strong>) but also the basis for the closed-loop controller (AN528)<br />
it is not completely packed, and some different adjustment possibilities are not described, if it’s<br />
used as the <strong>AN527</strong>.<br />
Features:<br />
• Secured against wrong polarity<br />
• Secure of short-circuit<br />
• External switch-off ramp<br />
• Ramp with quadrant identification<br />
• Wide range of ramp adjustment<br />
• External enable (no-load current circuit)<br />
• Test jack for: command signal, valve current<br />
• Same potential of: minus of the supply voltage,<br />
zero-potential of the inputs,<br />
zero-potential of the reference voltage<br />
• PWM - output stages (high dynamic)<br />
• 4 different inputs for the most popular input-voltages and -currents,<br />
allows very flexible input switching<br />
• LED indication for: Power on, Ramp off, Fail-safe<br />
• Potentiometer for: Ramp time, Zero overlapping, Gain<br />
The pin assignments and functions of the <strong>AN527</strong> are compatible with the AN227.
