Signal Electronics
Control monitoring electronics
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 world class standalone 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 as for example power or equipment/furnishing can also benefit from the tremendous Liebherr expertise in power and signal electronics.
Static inverter
Liebherr develops static inverters, which offer a reliable, lightweight, fully digital solution. They are based on wide band-gap technology together with enhanced connection functions.
Main product features:
- 120 VAC 60Hz single phase, 115 VAC 400Hz single phase (emergency)
- Comprehensive power conversion range (from 100 W to 2 kW)
- Internal monitoring and protection
- Digital control and communication : smart/tunable monitoring and protection capability
- Fanless design up to 500 VA: lightweight, reliable (200 kOH), competitive
- TSO/ETSO certification
Generic purpose REU
Another 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
