EA27 : CompletePower™ Drives
Technology: Brushless PWM
Quadrants: 2
Nominal Current: 8 to 24A
Quadrants: 2
Nominal Current: 8 to 24A
For BLDC Motors. Up to 1680W.
This two-quadrant brushless DC speed control is fully enclosed in a rugged aluminum case which can be DIN-rail mounted of panel mounted for easy integration. The drive includes ramp generator and braking functions for controlled acceleration and deceleration. Mode of operation is set by simple DIP switches. Either the 8A, 16A or 24A versions of this drive can be powered by the same 11 - 70 VDC range of supply voltage. The drive is protected against over-current, 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.
