SCA-B4-70 Drives
CompletePower™ Series

Summary Details

Technology: Brushless Servo
Quadrants: 4
Nominal Current: 10A or 30A

For Brushless Motors. Up to 2100 W.
This four-quadrant brushless DC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted or DIN-rail 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 jumpers. Both the 10 A and 30 A versions of this drive have an adjustable current limit and can be powered by the same 11 - 70 VDC range of supply voltage. The drive is protected against over-current and over-temperature and 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.
