Regenerative Speed Controls – General Information

Regenerative Drives open-chassis for 5HP - 180V DC motors with PM or shunt wound fields. These drives provide electronic control of speed and direction, eliminating the need for mechanical contactors and realys.

Benefits of Regenerative Drives:

• Bidirectional motor control with smooth acceleration/deceleration
• Energy recovery: Power is fed back to the grid during braking or overhauling loads
• 4-quadrant operation: Full-speed control in both directions with full torque
• Ideal replacement for servo drives in many motion control applications

NOTE:

These Drives can Operate 2-3HP-100V DC Motors as well,
