Liebherr’s power electronics and electrical drives are integrated into highly engineered equipment such as electro-hydraulic actuators (EHA), electro-mechanical actuators (EMA), electrical backup hydraulic actuators (EBHA), high power high-speed electrical compressors, electrical air conditioning packs, electrically-driven pumps, and electrical landing gear retraction actuators.

Liebherr’s signal electronics have demonstrated their ability to fulfill the highest criticality missions when so requested by the aircraft manufacturers, like for example for primary flight control computers or for engine bleed air computers.

The control software can be hosted by dedicated controllers designed and manufactured by Liebherr or by IMA modules as selected by the aircraft manufacturer.

The electronic products developed by Liebherr as an integral part of a flight control, air management or landing gear system can also be applied for multiple other applications on an aircraft. Different ATA chapters can benefit from the tremendous Liebherr expertise in power and signal electronics.

An example is the generic purpose REU – A universal remote electronics for different AC applications.

• Safety critical applications in unpressurized areas
• Adaptable aircraft interfaces and attachments
• Universal and configurable analogue inputs and outputs for different interface evaluation
• System independent actuation control and cockpit controls evaluation
