Emergency Battery System Securaplane's XL249 Emergency Battery System has been selected by Gulfstream for the Gulfstream V aircraft. This system is used to provide emergency power for: Lighting, 28VDC bus back-up and Flight instrumentation. The XL249 provides 9 amp hours of power at 18 to 24 VDC measured at the one hour discharge rate. No need to remove from aircraft for capacity check Advantages Applications • Built-In Test Equipment • IRS/INS Back-up Power • No Deep Cycling • Avionics Back-up Power • No “Memory” Characteristics • Emergency Lighting • Inexpensive Battery Replacement • Emergency Bus Back-up • No Need to Remove for Capacity Check • Converts 115 VAC at 400 Hz to DC Batteries Sealed Lead Acid batteries (Dry Cells) provide excellent performance in extreme conditions. Battery compartment is designed for easy bat- tery change by maintenance shops. Six month storage capability and no scheduled maintenance. Battery Charger Precision charges battery from aircraft 115 VAC 400Hz power bus. Unit has the capability to operate in bulk or temperature compensated constant voltage charge modes. Contains overheat protection, built-in test and overload pro- tection. Battery will reach 80-90% full charge from a fully dis- charged state in one hour. Battery Test Battery test function, places a known load on the battery and measures the terminal voltage on load over 60ºF. Indicates low, mid or full battery level. No need to remove batteries to per- form capacity check. Diagnostics Continuous BIT monitors charger/control logic, battery cell volt- age and battery heater circuit. Front panel mounted BITE soft- ware exercises BITE circuits. Works in conjunction with battery level test to validate capacity check. Environmental Control Thermal blanket automatically controls battery ambient below 60ºF to optimize battery performance. Solid State Switching Battery outputs controlled by solid state switches capable of con- trolling (5) individual outputs. Each switch output has overcurrent protection and is checked by BITE.
