Lind LIVCO Module
The Lind LIVCO (Low Input Voltage Cut Off) Module provides
protection for both sensitive loads and batteries in 12VDC elec-
trical systems. The module disconnects the attached loads when
the 12V system voltage drops below about 10.3V. This protects
the system battery from becoming over-discharged, as well as
disconnecting the loads from potentially damaging undervoltage
conditions. Loads can be connected through the terminal block
and/or the cigarette lighter socket.
