SA45 : CompletePower™ Drives
Technology: Bipolar Stepper Drive
Nominal Current: 5A and 10A
Nominal Current: 5A and 10A
For Stepper Motors. Up to 500W.
This bipolar stepper drive provides microstepping to 1/16 resolution built into a fully enclosed rugged aluminum case. It can be DIN-rail mounted or panel mounted for fast integration. The mode of operation is set by simple DIP switches. Features include an internal oscillator that allows operation of the drive at an internal speed set-point or with an external analog speed reference that can scale this set-point. Both the 5A and the 10A versions of this drive can be powered by the same range of voltage supplies. This drive is protected against over-current, over-temperature and incorporates the state of the art dual full bridge MOSFET driver for maximum efficiency. Connectivity is tool-free with RJ45-CAT5 plugs for the control inputs and push-type terminals for power. The optically isolated control circuit can be powered with an internal 5V supply on the drive for TTL step and direction compatibility or supply an auxiliary voltage supply for up to 24V logic step and direction.
