Converters ELL 4ХХХ

Digital thyristor converters of the 4XXX series for DC motors with independent excitation

The 4XXX series converters are designed for precise and high-precision control of the speed of movement and/or torque of mechanisms, machine tools, and various systems that use DC power. Thanks to special technologies of a wide range of action combined with large-scale integration of sensors, controllers, servo drives and/or feedback systems that ensure minimal deviation from the set speed, the 4XXX series digital thyristor converters provide control in important industries where high accuracy is required, for example:

• industrial machine tools (CNC) for material processing;
• robotics for synchronization of movements in multiple axes;
• UAV and automotive industry for stabilization of speed and direction (cruise control and position accuracy);
• shipbuilding and electric motors for precise positioning;
• other unmanned systems.

The 4XXX series digital converter is a new generation of intelligent thyristor systems operating on the basis of modern digital DSP/FPGA technologies. Thanks to the convenient filter settings in this category of the EURO-CONTRACT website, you can quickly select the necessary converter by characteristics:

• supply voltage;
• control type;
• execution type;
• armature current of the electric motor;
• excitation current.

A short list of the capabilities of the 4XXX series thyristor converters:

• speed control;
• torque control;
• position control with an internal position setpoint;
• position control with an external pulse position setpoint.
• thyristor converter synchronization, which allows reliable operation when powered from a network with powerful interference;
• flexible setting of speed controller parameters, including their action thresholds;
• active compensation function of the gearbox or ball screw with the possibility of its full compensation of the error;
• implementation of ultra-low engine speeds;
• and much more.

This is a short list of the capabilities of thyristor converters of the 4XXX series, it is more difficult to find what it cannot do - than what it can.
