SCA-L Drives Technology: PMDC Servo Amplifier Quadrants: 4 Nominal Current: 3A For Brush-Commutated PMDC Motors. Up to 75 W. This linear four-quadrant PMDC DC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted for easy integration. The drive is available in several configurations depending on your control requirements. The drive handles continuous currents up to 3 Amps and is protected against over-current, over-temperature and motor short-circuit. SCA-S Drives Technology: PMDC Servo Amplifier Quadrants: 4 Nominal Current: 6A For Brush-Commutated PMDC Motors. Up to 150 W. This PWM four-quadrant PMDC DC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted for easy integration. The drive is available in several configurations depending on your control requirements. The drive handles continuous currents up to 6 Amps and is protected against over-current, over-temperature and motor short-circuit. SCA-SS-70 Drives 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.
