SCA-B4-70 : CompletePower™ Motion Control
Technology: Brushless Servo
Quadrants: 4
Continuous Current: 30A



For Brushless Motors. Up to 2100 W.
This servo-amplifier is built in a rugged, compact aluminum case. Mode of operation is set by simple jumpers. This drive handles a wide range of power supply voltages (from 11 to 70VDC) for a variety of power input requirements. Inputs include set value and enable. The drive handles continuous currents up to 30A. The pulse-width modulated power stage utilizes 95% efficient MOSFET technology and is protected against over-current and over-temperature.
