Emergency Power Supply

The Extant Aerospace Emergency Power Supply (PS) products provide continuous standby power for self-contained gyro horizons and essential flight instruments. During normal operation, the aircraft system supplies power to the battery pack and indicator. During a power failure, the Emergency Power Supply batteries take over supplying power to essential instruments without interruption. The unit is capable of withstanding severe performance requirements, including thermal shock and high charge and discharge rates.
