Control and Protect
Our Aerospace specific Primary Power Distribution unit (PDU) provides primary power bus connectivity, transfer, and distribution functions to the aircraft loads. It includes a combination of electro-mechanical power contactors and solid state switches to control the power into and out of the unit. The Primary PDU critical circuit protection can be achieved through a design combination of current limiters, circuit breakers, and over-current sensing electronics to protect the power system and electronically controlled devices from dangerous faults.
Each Primary PDU is designed with a fail-safe philosophy that provides a default operating mode that permits, as a minimum, the application of battery and generator power to the appropriate loads, ensuring that power is maintained on emergency and essential buses.
AMETEK's Primary PDU can also integrate utility control in the box with light control, fuel balancing, air-conditioning control, air & fuel valve control, WOW logic and fan speed control. In addition, it uses solid state relays for direct control of loads such as tail de-ice, windshield heat override, and fuel boost pump.
