SCA-S : CompletePower™ Drives
Technology: PMDC Servo Amplifier
Quadrants: 4
Nominal Current: 6A
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.
