Thyristor converters ELL 4ХХХ-ХХХ-ХХ

Thyristor converters ELL 4ХХХ-ХХХ-ХХ

4XXX series digital thyristor converters for direct current DC motors with independent excitation.

    The 4XXX series thyristor converters are developed on the basis of modern digital technology (DSP / FPGA). They are fed directly by the power mains and provide three zones, four quadrants speed control of motors. In the first zone speed is regulated according to constant torque, in the second zone to constant power and in the third zone with reduced of the power. There are speed regulation mode and mode of torque control.

    Depending on the functionality, 4XXX converters are divided into four series:

  • 4XXX-XXX-1X - basic series with speed and torque control;
  • 4XXX-XXX-2X - series with position control from an internal assignment with MODBUS;
  • 4XXX-XXX-3X - series with position control from an internal reference with MODBUS and a function for active compensation of mechanical backlash;
  • 4XXX-XXX-4X - series with position control from internal reference, with position control by impulse reference and a function for active compensation of mechanical backlash.

    To select a converter, we recommend using the symbol structure:
