EA47 Drives
CompletePower™ Series

Summary Details
Technology: Brushless Servo-PWMQuadrants: 4
Nominal Current: 9 and 18A
For BLDC Motors. Up to 1260W.
This four-quadrant brushless DC servo amplifier is fully enclosed in a rugged aluminum case which can be DIN-rail mounted of panel 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 DIP switches. Both the 98A and 18A versions of this drive have an adjustable current limit and can be powered by the same 9 - 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 tool-free with RJ45-CAT5 connectors for control/feedback inputs and push-type terminals for supply power and motor connections.
