AN203

Servo Amplifier

The AN203 servo-amplifier has been designed for pressure control circuits with position-controlled pressure valves.

Card types:

AN 203 - 10 - 08 800 mA
AN 203 - 10 - 16 1600 mA
AN 203 - 10 - 25 2500 mA

Performance features:

• Reverse-polarity-proof
• Short-circuit protected
• Ramp can be externally deactivated
• External Stop
• Measuring sockets for target value ("setpoint") and valve current
• Minus potential of power supply is identical to the zero potential of the inputs and the zero potential of the reference voltage. Multiple servo-amplifiers can therefore be operated from a common power supply.
• Good dynamics, thanks to the use of high-speed end stages
• Broad ramp setting range
• Five different inputs for the most common input voltages and input currents, therefore extremely flexible input circuit configuration
• Pulse-width modulation
• Path-encoder monitoring on the valve
• Servo-amplifier can be operated with an I-min jump by resoldering a jumper
