OVERVIEW OF DC POWER DISTRIBUTION ASSEMBLIES Built around the Leach family of busbar contactors and current sensors, a wide range of DC power distribution assemblies are flying on or in development on the following programs: Examples: Eurocopter EC 120/EC135/EC155 Agusta A109/A119 Alenia C27J Dornier 328 Westland Super Lynx 300 Saab Gripen JAS39 Bell 609 TILTROTOR Aermacchi M346 Designed and manufactured by Leach to satisfy all specific program conditions, these assemblies offer a number of configurations from simple contactor primary distribution -- to fully integrated primary and secondary distribution -- including control logic and protection. Key Features and Concepts Include: 200 to 400 Amp power ratings for the main bus capability Modular concept used on programs where flexibility is required for easy reconfiguration and options Distributed or integrated architecture for optimized adaptation to aircraft specificities Secondary distribution associated to primary by plugged module or articulated junction Contactors and sensors assemblies designed to be Line Replaceable Units (LRC) Advanced electronic control logic that includes:     - A fully automatic Power On Built-in-Test (PBIT)     - Fully re-programmable control logic     - Continuous Built-in-Test (CBIT)     - Over-current protection     - TRU and battery over-temperature protection     - Under and over-voltage protection     - Short circuit protection     - Automatic reconfiguration in case of short circuit or component failure     - RS422 communication line between boxes and between each box and the cockpit control panel
