Emergency Battery System XL246-A Securaplane’s XL246-A is an Emergency Battery System providing 6 amps of power at 18 to 24VDC. This unit is currently available and PMA’d on Canadair Challenger 601-3A/3R, Falcon 50, Gulfstream G-Ill, MD-80, and soon on MD-11 as well as many other aircraft types. The XL246-A is a direct replacement for the ACME AMPS 2000 on all these aircraft types. Direct Replacement for the ACME AMPS 2000 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 • Communications Back-up Power • Full 3 Year Warranty on Batteries • Full 5 Year Warranty on Electronics • No Need to Remove for Capacity Check Batteries Sealed Lead Acid batteries (Dry Cells). 24V 6AH at the one hour discharge rate. Provides long life, six month storage capability, and requires no scheduled maintenance. Battery Charger Precision charges battery from aircraft 28 VDC 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 protection. Battery will reach 80-90% full charge from a fully discharged 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 perform capacity check. Diagnostics Continuous BIT monitors charger/control logic, battery cell voltage and battery heater circuit. Front panel mounted BITE software 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 All switching is performed through low loss solid state circuitry. Information is subject to change.
