WILMINGTON, MA - With the first completed Bombardier* Global* 5000 high-speed business jet now in service, Bombardier has set a new standard for advanced cabin electronics capabilities.

The Global 5000 aircraft offers the latest advancements in corporate aviation, including the first application of Rockwell Collins Ethernet-based Airshow 21 cabin electronics system, leveraging state-of-the-art technology and a flexible digital architecture to bring unprecedented capabilities and control to this best-in-class business jet. The system fully addresses the need for enhanced in-flight capabilities including business connectivity, information, entertainment, and cabin environmental control management.

Eleven AC and DC power distribution units produced by AMETEK Aerospace & Defense are key elements of the Airshow 21 power distribution subsystem installed on the Bombardier Global 5000 business jet. Each PDU utilizes AMPHIONÔ Solid-State Power Controllers (SSPC) and replaces the traditional circuit breaker panel architecture. AMPHION provides circuit protection as well as the capability to remotely switch power to devices, monitor load voltage and current, and relay data on performance trends and prognostics for preventive maintenance.

AMPHION’s patented circuitry prevents a device failure in a short-circuited condition, while its unique "fail-open" feature prevents a load from remaining powered and unprotected. Its load management abilities offer additional features of emergency power bus load control and isolation, load balancing and shedding.

Although integrated into the Bombardier Global 5000 aircraft’s Cabin Electronics System, the AMPHION PDU has applications throughout an aircraft, including cabin and galley systems, engine controls, interior and exterior lights, fuel and oil pumps, utility systems and control surface actuators. It can be used with a host of aircraft devices, replacing mechanical or solid-state relays and traditional circuit breakers.

The AMPHION PDU is based on patented circuitry that serves as the building block for an entirely new architecture for the control and distribution of aircraft power. Each PDU provides 12 or more digitally controlled circuits with customizable over-current trip settings. The AC PDU offers control of multi-phase AC loads by logically linking the control of multiple power controllers. AMPHION PDUs can handle loads up to 15A per channel and multiple PDUs can be installed on the same digital bus using unique configuration identification through external pin-strapping.

AMPHION PDUs can be located throughout an aircraft, allowing for easy configuration changes and providing maximum flexibility for customizing aircraft interiors. It eliminates the need to route electrical wires to a centralized location, significantly reducing the amount of wiring, simplifying installation, saving weight, and increasing system reliability.

AMPHION technology is available in multiple packages from custom PC board mounted devices to stand-alone, military relay and circuit breaker envelopes. Its unique arc-fault detecting ability allows it to trip on intermittent faults produced by wire insulation failure and other causes. It can distinguish between the fault current pattern typical of an arc and normal inrush surges or other types of current peaks. Specific packages, such as the MS-3320 style AMPHION circuit breaker, also can provide a visual indication of the fault type and communication over an industry standard single-wire data bus.

With its thin, flat profile, the AMPHION PDU can be mounted in a cabin wall or other space restricted areas. Two models are available: a 120-VAC, 40-amp version with 12 circuits and a 28-VDC, 30-amp version with 16 circuits. Both models feature programmable over-current trip settings for each circuit utilizing a field adjustable personality module that is specifically configured for each aircraft location during installation.

The new high-speed intercontinental Bombardier Global 5000 business jet is capable of flying non-stop from continental Europe to central North America at Mach 0.85. With the most spacious cabin in its class, the aircraft is designed to execute transcontinental missions at Mach 0.89 - faster than any competing jet. The Bombardier Global 5000 aircraft flies executives and government leaders in and out of airfields closer to their point of business than any other competing business jet.

AMETEK Aerospace & Defense is a leading supplier of engine and aircraft monitoring systems, data acquisition units, fuel and fluid measurement systems, cockpit instruments and displays, engine and airframe sensors, cables, harness assemblies, avionics blowers, fans, and heat transfer and cooling systems. It is a unit of AMETEK, Inc. (NYSE: AME), a leading global manufacturer of electronic instruments and electric motors with annualized sales of more than $1.4 billion.
