AMETEK’s Power Distribution Unit (PDU) is a device that replaces centralized circuit breaker panels allowing for power to be more efficiently distributed and controlled via a data bus.  PDUs can be located throughout the aircraft allowing for easy configuration changes if additional power is required thus providing maximum flexibility in custom interior design. In addition to being a circuit breaker, AMPHION technology provides load monitoring that can be used for trend monitoring of electrical devices and automatic load shedding  The AMETEK PDU has 16 DC or 12 AC channels per unit that can easily be installed beneath interior panels or multiple PDUs can be stacked to increase the number of channels in a particular location. No active cooling is required due to very low heat dissipation.

The Secondary Power Distribution Unit (SPDU) leverages digital communications and the use of solid-state technology to develop a highly configurable and flexible power distribution system. The SPDU is designed to be used in multiple locations throughout the aircraft and employs the latest design features to address the most current aircraft safety and performance requirements. The SPDU is capable of switching up to 288 amps of 28V DC current and controlling up to 54 independent channels using Solid State Power Controllers (SSPCs).
