The E-AC series microstepping drive is a low-cost, high-performance, high-reliability stepper drive in a small package. The design of the E-AC is based on the well proven ZETA and OEM750 microstepping drives. It provides up to 3.5 Amps of current to the motor and accepts 120VAC direct-online power only. All step motors are subject to mid-range instability or oscillations - the E-AC incorporates an anti-resonance circuit that aggressively and effectively suppresses these oscillations, thus taking advantage of the full capabilities of the step motor.

E-AC Low Cost Microstepper Drive - Features:
• Drive Input Supply : 1*120VAC (95 - 132VAC)
• Output Current : 2.47 Arms / 3.5 Apk
• Resolution : 50,800 steps/rev
• Motor Inductances : 0.5 mH - 80mH
• 3-State Current Control (allows the drive and motor to run cooler and more efficiently than 2-state drives)
• Auto Standby (reduces motor current and heating at rest)
• Four Predefined Current Waveforms (to optimize smoothness)

Protection:
• Optically isolated step and direction inputs
• Short circuit protection – phase-to-phase and phase-toground
