The SureStep® STP-DRVAC stepper drive is powered from either 115VAC or 230VAC and is intended for use with step motors designed to handle high bus voltage. MTRAC motors are designed to work with the 115 or 230 VAC powered drives. Auto-setup configures motor current control and anti-resonance gain settings. The high voltage drive (priced at $199.00) uses 90 to 240 VAC input (selected by switch) and output current is settable from 0.6-2.5A/phase (peak of sine). Microstep resolution is switch selectable with 16 settings from 200 to 25600 steps/rev. High voltage, high torque MTRAC motors are available in single and dual-shaft configurations with steel case and stainless-steel shaft(s). Starting at $57.00, SureStep MTRAC motors are available in NEMA frame sizes 23 and 34 with holding torques from 75 to 1841 oz-in.
