MCI 25B
Product description
MCI 25B motor controller with brake is designed for soft starting and braking of 3 phase AC motors. The digital controlled soft
starter features accurate settings and several monitoring functions. Acceleration time and initial torque are along with the braking
torque easily adjusted.
During braking the MCI 25B will apply a DC current to all the windings of the motor, thus providing a powerful brake function.
The automatic stop detection ensures a safe operation. For positioning applications the unique slow speed function can be applied.
Typical applications
The MCI 25B controller is typically applied on demanding braking applications such as saws, cranes, grinding machines,
automatic doors, etc.
