Sheet 1 of 4
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 regu-
lated 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 recov-
ery.
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 85^oC.
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 bat-
tery 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.
