Stepping System Power Supply Introduction
The SureStep stepping system power supplies are designed to work with SureStep
microstepping drives and motors. The different power supply models can provide
unregulated DC power at the applicable voltage and current levels for various
SureStep drives and motors. The power supplies also provide a regulated 5VDC,
500 mA logic supply output for indexer and PLC logic outputs to control the
SureStep drives. Automation Direct switching power supplies PSB12-xxxS, PSB24-
xxxS, and PSB48-xxxS are good non-linear supplies. A regen clamp may be
needed if using these supplies. For more information on using the power supplies
please see Chapter 7: “SureStep System Power Supplies”.
The stepping system power supplies can supply power for multiple SureStep
STP-DRV-xxxx microstepping motor drives, depending on step motor size and
application requirements.
Refer to the Power Supply chapter of this user manual for complete details on
the specifications, installation, mounting, dimensions, and wiring of the SureStep
stepping system power supplies.
Further information about braking accessories and regeneration clamping can
be found in Appendix A: “SureStep Accessories” and the STP-DRVA-RC-050
REGENERATION CLAMP datasheet.
