DA43 : CompletePower™ 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.
