Converters for traction drives

One of company’s priorities is design, manufacture and implementation of electrical equipment for rolling stock of urban electric transport.

Converters produced by ASC have a wide range of input voltage (550 V ±55%).

Quick response provides immediate emergency shutdown of the drive.

Converters are maintenance-free except for air ducts that require cleaning.

Manufactured equipment is microprocessor controlled, has analog and digital I/O with different serial communications interfaces according the purpose of use.

For AC motors used in urban electric transport autonomous voltage invertors of different modifications are produced. They ensure good dynamic characteristics, smooth rotation for the whole operating range and low input current at the start.

Several modifications of converters based on IGBT modules are produced for DC motors.
