Liduro LCU300-NG2 Power electronics modules

The liquid-cooled LCU-300-NG2 power electronics module from Liebherr covers the power range from 1,000kW to 2,000kW in just one size. The power electronics module can be configured as a drive or regenerative unit and can be planned in parallel operation for multiple-axis drive units with a common intermediate direct voltage circuit for maximum ratings and partial redundancy. The power electronics modules can also be supplemented with a braking chopper with the same size. Tailored and parameterisable control systems allow precise and highly dynamic processes in industrial applications with Liebherr control units.
