SCA-SS-70 Drives
CompletePower™ Series

Summary Details

Technology: PMDC Servo
Quadrants: 4
Nominal Current: 10A or 30A

For Brush-Commutated PMDC Motors. Up to 2100 W.
This PWM four-quadrant PMDC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted for easy integration. The drive can be configured in a variety of torque and speed control modes with the mode of operation being set by simple DIP switches. The drive handles continuous currents up to 30 Amps and provides a peak current of 60 Amps. The drive is protected against over-current, over-temperature, motor short-circuit and incorporates state of the art MOSFET technology for maximum efficiency. Connectivity is achieved with simple screw-terminals for control/feedback inputs, supply power and motor connections.
