PRODUCT FUNCTION
The LFP1225(LV)/LFP1240(LV) is a two stage, 12V DC-DC battery charger that operates
from an alternator input of 12V nominal or a 12V nominal solar panel input. The LFP1225/
LFP1240 will also charge from an alternator input of a 24V nominal vehicle*
1
. The input
voltage of the LFP1225(LV)/LFP1240(LV) can be above, below or equal to the output
voltage making it ideal for charging an auxiliary 12V battery where the distance from the
main battery may cause a significant voltage drop. The LFP1225(LV)/LFP1240(LV) is also
designed to isolate the main battery from the auxiliary battery, to avoid over-discharging
the main battery.
