GG-1508-20 The GG-1508-20 power converter is a nominal 36 volt to 13.8 volt dc—dc converter. This device is designed for use on trains, buses, trucks, or other automotive devices where clean regulated electrical power is required. The input of the converter is protected against polarity connections. The converter is also protected against thermal and over voltage input with automatic recovery. The converter can handle vibration and shock as is normally encountered in the automotive environment and storage temperatures of 85o C.
