8.3A 3-Phase Stepper Drive with Dual DC/AC Input

The 8.3A 3-Phase Stepper Drive 3DM860H is rated for up to 8.3 A of output current and accepts either 24-110 VDC or 18-80 VAC input, giving integrators freedom to use a common DC bus or line AC depending on the machine architecture. Lyenwsin supplies this drive for CNC equipment, material handling, and industrial automation.

Control Mode

The drive operates on Pulse/Dir and CW/CCW pulse inputs, making it compatible with standard step controllers. Running open-loop, it positions by commanded steps without feedback wiring, keeping the system simple and the commissioning fast.

Protection and Smooth Output

Overcurrent, overvoltage, and undervoltage detection guard both input supply and motor phases. The output is shaped for low noise and vibration, so stepper motion remains stable and quiet across varied duty cycles.

Key Specifications

  • Output current: max 8.3 A
  • Supply voltage: 24-110 VDC; 18-80 VAC
  • Control modes: Pulse/Dir, CW/CCW pulse
  • Protection: overcurrent, overvoltage, undervoltage
  • Operation: open-loop, low noise and vibration

Target Applications

It suits industrial automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing.

System Design

Pair with a 3-phase motor whose phase current fits within 8.3 A. The dual DC/AC input lets you reuse one drive design across machines powered from different supply rails. Confirm the motor torque at operating speed for the intended axis. Lyenwsin can assist with motor selection and system integration.

Distributor Support

Lyenwsin keeps the 3DM860H in stock with matched 3-phase motors and provides torque-speed data, wiring guidance, and configuration support for fast deployment across machines powered from different supply rails. Our engineers can help verify the DC or AC input arrangement and the motor current rating before ordering, and we can advise on wiring and protective devices for the supply bus, including fuse selection and cable cross-sections for the drive.
