Overview

The Integrated Battery Back-up System (IBBS) provides an engineered solution to enable an endurance bus for critical loads found in aircraft. The IBBS system provides back-up power to critical electronic loads such as EFIS, GPS, Autopilots and engine monitoring systems.

Integral to the IBBS is a lithium-iron-phosphate battery pack and a matched charging system to ensure the battery is properly charged and maintained. The system includes switching circuitry to provide a stable source of output power during both normal and emergency operations. The IBBS system also provides signals to other equipment such as EFIS systems to communicate the operating state of the back-up bus as well as the state of the battery.

The IBBS system connects to the standard aircraft power bus and provides an output to critical equipment that requires back-up power. Additionally, the IBBS system provides surge and sag protection for connected equipment, allowing operation of critical equipment during engine starting.

The IBBS system is suitable for use with equipment such as Garmin GNS and GTN series navigators, G3X series of avionics, Grand Rapids Technologies EFIS systems, Advanced Flight Systems EFIS, Dynon EFIS, and MGL EFIS, TruTrak Autopilots and EFIS, and Trio Autopilots.
