115V/220V 4Q DC Motor Controller Manufacturer

. Summary

MMT-SCR series DC motor controllers are full-wave positive feedback motor controllers and can control motors in It provides four-quadrant operation, which can realize positive and reverse torque in two speed directions.

.Product Features

1. Applicable to permanent-magnet, separate excitation DC motor

2. Large torque for low-speed start-up.

3. The mechanical characteristics of hardness, static error rate of 1%.

4. A wide speed-regulating range (0 - max).

5. A rapid dynamic response process.adjustable

6. Automatic and smooth transition process during acceleration or deceleration.

7. Current setting and current limiting protection (If the preset current value is exceeded, the driver stops output automatically.)

8. Setting functions of and opposite soft start/soft stop time (adjustable)

9. Self lock-up function.

10. Positive rotation and reverse rotation are selectable.

11. Dual closed loop PI adjustment (Current and Voltage)The closed-loop feedback is selectable.

12. The speed control mode and torque control mode are .

13. The inertial gliding stop and braking stop are selectable.

14. The input voltage and output voltage are selectable.
