General Details

ELAS – DB2

The series AС servo drives ELAS is intended to drive АС servo motors. They are completed with brushless synchronous electrical motors with permanent magnets in the range from 0,55 kW to 11,0 kW and are intended to control high precision machine tools, robots and complete positioning systems.

It is designed for the following voltage supplies and motors power:

  • 200 – 230V 1 ~ 50/60Hz – motor power 1,5 kW to 2,2 kW
