Detailed Product Description

SCR DC Controller

MMT-220DR15AL

i. Overview
MMT-Silicon Controlled Series is more reliable and stable by using the unique triggering
mode. It adopts SMT technology and features small size, simple structure and large output
power. To date, it has been applied in a wide range of areas in view of the proven advantages
in both capacity and characteristics of the series.
Applicable areas
MMT series DC motor can be used in machine tools and paper making, presswork, weaving,
printing and dyeing, optical fiber cable equipments, packaging machines, electrician-used
equipments, food processing machines, rubber producing machines, biology-related
equipments, PCB printing equipment, experimental equipments, welding and cutting
equipments, light-duty equipments, logistics equipments, motor vehicles, medical equipments,
and communication equipments, etc.

ii. Product Characteristics

SMT technology is adopted. It features small size and light weight.
Applicable to permanent-magnet, separate excitation DC motor.
Dual closed loop PI adjustment (Current and Voltage)
Large torque for low-speed start-up.
It has relatively hard mechanical features. The static-state error ratio is 1%.
Wider speed adjusting range
Faster dynamic response process
Automatic and smooth transition process during acceleration and deceleration.
Current setting and current limiting protection (If the preset current value is exceeded,
the driver stops output automatically.)
Upper range/lower range speed can be adjusted at will.
Soft starting/stopping time setting function. (0.215s)
Keyboard lock-up function.
Output current inspection function: The driver monitors the real time output current
automatically. If the current acts abnormally or exceeds the set value, driver will
automatically stop the output and maintain the fault state.
Input and output voltage can be selected.
