LSC 4-Q-DC Servoamplifier 4-Q operation Controlled operation for acceleration and braking in both directions. Linear power stage Ideally suited for small outputs power, low electromagnetic emission, no motor choke required. Operating modes IxR compensation, voltage control, encoder speed control, DC tacho speed control or current control selectable with a switch from outside. Design Robust metal housing with variable installation options on assembly plate or 19 rack. Set value input Via external potentiometer, external set value voltage or using inter- nal potentiometer. Easy start-up procedure Pluggable screw type terminal block, simple set-up with potentiom- eter, robust designed PI controller. Excellent price / performance ratio Good value 4-Q-DC servoamplifier matched with small permanent magnet activated DC motors.
