2A AND 10A BATTERY CHARGERS
There are two types of battery chargers. A 2 Amp bat-
tery charger and a 10 Amp battery charger.
The 2 Amp battery charger is a "float" type charger. A
"float" type charger will charge the battery at its maxi-
mum output current rating until the battery voltage
reaches a "float" voltage and then the charge current
will decrease to maintain the battery at that "float"
voltage.
The 10 Amp battery charger is an "equalize" type
charger. An "equalize" type charger will charge the
battery at its maximum output current rating until
the battery voltage reaches an "equalize" voltage and
then the charge current will decrease to maintain the
battery at a lower "float" voltage.
The 2 Amp charger incorporates fuses on both the
input AC line and the battery charger output. The
input AC line fuse is a Littelfuse 2 Amp, Slo-Blo Fuse,
5x20mm, P/N 218002. The AC line fuse is located on
the charger printed-circuit board. The output DC bat-
tery fuse is a Littelfuse 5 Amp, Mini-Blade Fuse, P/N
297005. The battery fuse is located on the charger
printed-circuit board.
The 10 Amp charger incorporates fuses on both the
input ac line and the battery charger output. The
input AC line fuse is a Littelfuse 5 Amp, Slo-Blo Fuse,
5x20mm, P/N 218005. The AC line fuse is located
on the charger printed-circuit board. The output DC
battery fuse is a Littelfuse 15 Amp, ATO Fuse, P/N
257015. The battery fuse is located on the charger
printed-circuit board.
These chargers require that the battery be connected
to the charger in order to turn on. The battery voltage
must also be above a certain "boost" voltage for the
charger to turn-on.
The boost voltage required is approximately 11 volts
for a 12V system. If the battery open-circuit voltage is
less than the above boost voltage, it is recommended
that the battery be checked.
If the voltage of the generator's 12V battery exceeds
15VDC, during normal charging operation, the bat-
tery should be checked. Typical battery voltages,
when a 12V battery is being charged, should be in the
13VDC to 15VDC range.
The 2 Amp and 10 Amp chargers are UL recognized
for use in the R-panel enclosure and are not to be
operated outside the R-panel enclosure.
