DC-Motor Control Station BUNA

Control station BUNA

Purpose:

Is designed for DC drive motor power supply of pump (or other machinery), drive motor speed regulation in the range of 0-100%, automatic control of the armature speed level, maximum current and drive moment. Three-phase AC power supply system with rectified voltage is employed.

Control system of the system ensures:

-         drive motor speed regulation in the range of 0...1000 rpm.

-         peak motor current – 1300А.

-         self-diagnosis

-         emergency alarm.
