Liduro Frequency Converters
Liduro Frequency Converters
Your efficiency and operational safety
Drive systems for maritime, wind energy and industrial applications: The Liduro Converter for electric drive systems is distinguished by its high power density and protection level. All components of the liquid-cooled system are low2no maintenance products. They are designed for reliable operation in extreme ambient conditions and meet the highest requirements regarding lifetime, operational safety and efficiency.
The AC/AC and DC-Bus multi drive systems have power ranges from 110 to 4,000 kW and are available as stand-alone and complete systems.
Application-specific solutions: Liebherr is a technology leader and partner with decades of experience in the development of application-specific drive systems. Based on our flexible and scalable product system, we are providing complete solutions according to customer-specific requirements.
Low2no maintenance
Liduro systems are low2no-maintenance products based on their design, quality and protection concept. Continuous monitoring of processes and status information increase the intrinsic protection and extend the device's overall operating time.
Active overvoltage protection: Very fast overvoltage protection functions (active clamping) directly on the semiconductors prevent semiconductor failures due to transient overvoltages.
Less space required, fewer failures: The optional brake chopper of the converter unit supports dynamic braking processes for motors or generators, with the same module size.
Application-specific control functions: The power modules can be parameterized using software for highly dynamic drive solutions and complex control functions.
Reduced spare parts inventory: The power supply units and the motor/generator units are equally sized and can be interchanged as required. The function of the converter unit LCU 300 is determined by software.
Simple connections: The good accessibility of the phase connections from the front allows a quick exchange or power increase of the modules.
