SoftStep Drives
SS483 Series
Second-source compatible with the IM483 — at higher performance and lower cost.
Bipolar micro-stepping driver for motors in the 0.5–3 A RMS range on 12–45 V. Full-step and half-step machines convert to quiet, smooth micro-stepping with no software changes at all.
Direct replacement for IMS IM-483
