150-240VDC 3-Phase closed loop Stepper Drive with 8A Output

150-240VDC 3-Phase closed loop Stepper Drive

The 150-240VDC 3-Phase closed loop Stepper Drive 3HCS2208H runs from a 150-240 VDC supply and delivers an 8 A maximum output current. It is engineered for machine axes that need both torque and speed from a DC-powered bus, and it carries full closed loop control to keep those axes accurate. Lyenwsin distributes this drive for printing machinery, robotics, and packaging lines.

High-Bus-Voltage Performance

Operating at 150-240 VDC reduces the current required to deliver a given motor power, which lowers I²R losses in the wiring and lets the drive maintain torque at higher stepping rates. Machines with long rapid-traverse moves benefit most from this behavior, since the higher bus voltage lets the winding current build faster at speed.

Command Interfaces

Both Pulse/Dir and CW/CCW pulse modes are supported. The CW/CCW mode is particularly convenient on retrofit installations where the legacy controller already produces directional pulse trains.

Reliability Under Load

With full closed loop control, the drive monitors the motor’s actual position continuously and corrects for missed steps or transient load torque. This eliminates the cumulative position error that open-loop steppers exhibit, which is critical on repetitive production machinery.

Key Specifications

• Type: 3-phase closed loop stepper drive
• Supply voltage: 150-240 VDC
• Max output current: 8 A
• Command modes: Pulse/Dir, CW/CCW

Typical Applications

Industrial automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing, with emphasis on axes that need sustained torque at speed.

Selection Considerations

Verify the motor phase current fits the 8 A capacity and that the bus supply remains within 150-240 VDC under worst-case load. For continuous-duty lines, review the duty cycle against the drive’s thermal limits. Lyenwsin can recommend compatible motors and provide application engineering support.

Distributor Support

Lyenwsin keeps the 3HCS2208H in stock with matched 3-phase motors and provides torque-speed data, wiring guidance, and configuration support for fast deployment on production lines.
