WILMINGTON, MA - The Power & Data Systems Group of AMETEK Aerospace & Defense will provide its patented AMPHION™ Solid-State Power Controller (SSPC) to Cessna Aircraft’s for the Citation Mustang-the latest addition to Cessna’s highly successful line of business jets.

The AMPHION SSPCs are integrated into the junction boxes and windshield heater controllers aboard the new six-seat Citation Mustang. By combining the function of a solid-state circuit breaker and a relay into a single device, AMPHION power controllers eliminate the need for traditional thermal circuit breakers and relays.

In the junction box, the AMPHION SSPC provides load control directly from the primary power bus to critical and non-critical loads such as motors, fans, pumps, and various avionics instruments. The windshield controllers utilize an AMPHION Pulse Width Modulated SSPC that controls switching slew rates to reduce electromagnetic interference. Using AMPHION technology, the windshield controller is able to precisely control windshield temperature by modulating the power to the windshield heaters.

The AMPHION SSPCs are based on patented circuitry that serves as the building block for an entirely new architecture for the control and distribution of aircraft power. They provide 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 "fail-open" circuitry prevents a device failing in a short-circuited condition, preventing a load from remaining powered and unprotected. Its load management abilities offer power distribution system designers such features as emergency power bus load control and isolation, load balancing, and load shedding.

AMPHION SSPCs 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.

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.

AMETEK Aerospace & Defense also offers power distribution units incorporating the AMPHION SSPC technology. With their thin, flat profile, these power distribution units 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 six-seat Cessna Citation Mustang is considered an aviation breakthrough by offering exceptionally high levels of performance and value in a cabin-class, single-pilot business jet. Cessna has delivered more than 4,200 Citations in the last 30 years, including more light jets than all other manufacturers combined. The first Citation Mustang aircraft is scheduled for customer delivery in the fourth quarter of 2006.

AMETEK Aerospace & Defense is a leading supplier of engine and aircraft monitoring systems, data acquisition units, fuel and fluid measurement systems, 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.
