EA25 Drives
CompletePower™ Series

Summary Details

Technology: Brushless, Speed/Torque Control
Quadrants: 2
Nominal Current: 6A

For BLDC Motors. Up to 300W.
This two-quadrant brushless DC speed control is fully enclosed in an extremely small rugged aluminum case which can be DIN-rail mounted or panel mounted for easy integration. The drive includes an adjustable ramp generator for controlled acceleration and a torque mode. Mode of operation is set by simple DIP switches. This drive can provide 6 A of nominal current and can be powered by an 11-50 VDC range of supply voltage. The drive is protected against reversing, over-current, over-temperature and incorporates state of the art MOSFET technology for maximum efficiency. Connectivity is tool-free with RJ-45-CATs connectors for control/feedback inputs and push-type terminals for supply power and motor connections.
