DA43 Drives Technology: PMDC Servo-Linear Quadrants: 4 Nominal Current: 3A For Brush-Commutated Linear PMDC Motors. Up to 75 W. This servo-amplifier is built into a fully enclosed rugged aluminum case. Mode of operation is set by simple DIP switches. This drive handles a wide range of power supply voltages (from 11 to 70VDC) for a variety of power input requirements. Inputs include current limit, set value input and a ramp function. The drive handles continuous currents up to 3A. The linear power stage is protected against over-current and over-temperature. DA47 Drives Technology: PMDC Servo-PWM Quadrants: 4 Nominal Current: 9A and 18A For Brush-Commutated PMDC Motors. Up to 1260 W. This servo-amplifier is built into a fully enclosed rugged aluminum case. Mode of operation is set by simple DIP switches. This drive handles a wide range of power supply voltages (from 11 to 70VDC) for a variety of power input requirements. Inputs include current limit, set value input, enable, tach and a ramp function. The drive handles continuous currents up to 9 and 18A. The pulse-width modulated power stage utilizes 95% efficient MOSFET-technology and is protected against over-current and over-temperature.
