New Stepper Drive Range from RTA

Our RTA stepper drive range has been enhanced by the new NDC range of units which replaces the previous SDC and HGD series.

The full RTA range covers motor phase currents from 0.6 Amps/phase up to 14A/phase with motor bus voltages from 24 to 240V dc, and the drives are suitable for use with bipolar 2 phase 1.8 degree stepping motors from size 11 through to size 65.

The NDC series, available with plug and socket connections or screw terminals, has the benefit of ministepping at up to 4000 s/r and has a built in oscillator, useful in simple move applications. The NDC will operate from a DC power supply in the range of 24 to 75V dc and the two model variants offer a wide current range making them suitable for use with a variety of stepper motors. The similar SAC series operates from AC supplies.

For higher power industrial applications there are the GAC, GMH and GMD series with ratings up to 12A and 180V dc from either ac or dc supplies and the packaged MIND B/T series with up to 12A and 180Vdc. The X-MIND series operates directly from mains AC supply at 110 to 230V without the need of a transformer. Both the MIND B/T and X-MIND series have recently been expanded to cover a wider current range, while the MIND T incorporates an on-board motion controller. For even higher stepper motor performance the BCW02 gives 14A at up to 240Vdc. All drives have protection against short circuits at motor outputs, against under and over voltage and are thermally protected.
