GG-1570-20 The GG-1570-20 power converter / Backup Battery is a nominal 13.8 volt to 13.8 volt dc—dc converter With a backup battery to supply power during starting etc. 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 protects against transient up to 300 volts with an energy content of up to 10 joules. The converter can handle vibration and shock as is normally encountered in the automotive environment and storage temperatures of 85o C. The Battery backup can provide provide 2 amps for up to 12 minutes and of course lower currents for longer periods. The curve on page 2 shows the battery output voltage for current drains of 1.5 and 2.0 amps. A logic signal is available in the event of a power loss. This UPS is packaged in a small, metal enclosure for maintenance free operation.

Backup Battery Shutoff Timer: Disconnects the backup battery after 6 minutes. Ignition “Keep-Alive” Timer: Forces the “IGN OUT” signal to remain high for at least 8 minutes. Interrupt Logic: Sets interrupt logic signal “High” if any of the following occurs. • “12 v in” power is lost. • “12 v in” power drops below 10.6 v. • Driver turns off ignition.
