Intelligent Power Stabilizer (IPS) is an electronic power converter that provides stable power to critical electrical equipment found in general aviation aircraft. Electronic equipment such as engine monitors, EFIS and GPS’s can be operational before and during engine starting. With this important feature, the IPS saves fuel and operating expenses by not having to run the engine during flight plan loading or clearance delivery. When used with aircraft engine monitors, it ensures the pilot can monitor critical engine operating parameters such as oil pressure during the engine starting process. The IPS is available in three different models and is suitable for use with equipment such as the Garmin GNS-430/530 series of GPS and the G900X and GU370/375 series avionic system.

The patented technology in the Intelligent Power Stabilizer system ensures the connected electronic equipment is provided with a stabilized source of power even when the aircraft battery voltage drops significantly. This is particularly important during engine starting or alternator out conditions. IPS provides aircraft bus voltage surge and sag protection for the connected electrical equipment by actively clamping the regulated output voltage.
