ADS4-Q-DCServoamplifier
The ADS (Analog DCServoamplifier) is a powerful pulse-width modulated (PWM) servoamplifier forcontrolling permanent magnet activated DC motors.
Pulsed power stage
Suitable for controlling lowand high output power. 95% efficiency thanks to state-of-the-art MOSFETtechnology.
Operating modes
IxR compensation, encoderspeed control, DC tacho speed control or current control selectable with aswitch from outside.
Design versions
Robust metal housing inmodule form offers several mounting options. Standardized Eurocard version(with accessories) for the installation in a 19“-Rack or in a plug-in cardsystem.
Excellent controlcharacteristics
Stable speed behaviour whenset value and disturbance variable change, fast current controller.
Protection circuit
Protected againstovercurrent, thermal overload and short-circuit of motor cable.
Set value input
