ELECTRICAL SYSTEM
CHARGING YOUR BATTERIES
There are several different steps you can take to charge your XT battery system:
VEHICLE
(DC Charger may vary in your caravan, there are instructions outlined for each model)
Powertech DC to DC Boost Charger (MB 3691)
When your car is attached to the trailer and the Anderson plug is connected to your car, power comes
from your car through the Anderson plug and into the
Powertech DC to DC Boost Charger (MB
3691)
which monitors the voltage and makes compensation to ensure your battery pack (and the
break- away battery) is receiving the correct charging parameters. The main switch on the DC to DC
charger must be turned "ON" for the charger to provide charging voltage to the battery set. If it is
turned "OFF" then no power will flow to the battery set. There are 5 "dip" switches which are factory
set to 2 and 5 "on".
Turn ON the Power switch, the “POWER ON” LED lights up, this indicates the device is ready for charging. The
smart DC-DC boost charger will perform the four stage charge automatically The “BULK” LED lights up. This
means the battery charger is beginning at the 1st stage of charging.
The 1st stage is to ensure battery is always charged at the maximum charging condition.
This is to boost up the charging cycle and particularly wake up a weak battery to absorb energy.
After 10-20 mins, the charger will switch to 2nd stage, the “BULK” LED remains ON and the battery is charged
at the maximum current to the battery.
At the 3rd stage, the charger will switch to “ABSORPTION” mode, the red LED goes out and the yellow LED
lights up. The device is delivering constant voltage to the battery with reduced current.
At the 4th stage, the battery has been charged to about 90% of its rated capacity. The “ABSORPTION” LED goes
out and the “FLOAT” green LED lights up. The charging current is decreased and the charging voltage is held at
a constant level. Battery is now under “FLOAT” constant charging.
The system is protected by an external 60amp fuse marked "Anderson".
ELECTRICAL SYSTEM
Projector DC20
Battery charger that is NOT fitted with an on /off switch. Simply plug in the Anderson plug to your tow
vehicle and the projector DC20 does the rest. It is protected on the input side by a 40-amp fuse marked
"Anderson" and on the outlet side a 25-amp fuse located near the battery terminal in the battery box
marked "Anderson". This unit is also internally fused in case of reverse polarity on both input and output
sides. The projector DC20 uses a 3 stage charging system mainly "BULK", "ABSORBTION" and finally
"FLOAT", to ensure your battery is kept in fully charged state.
The system is protected by an external 60amp fuse marked "Anderson".
Projector IDC25
Combined DC to DC charger and solar controller. The IDC25 constantly checks between the solar input
and the car input and always selects solar if there is enough voltage being produced otherwise it selects
the car output or a combination of both car and solar input. The projector IDC25 uses a 3 stage charging
system mainly "BULK", "ABSORBTION" and finally "FLOAT", to ensure your battery is kept in fully charged
state. It has a panel that shows if solar or alternator is supplying the battery charge current. With the
solar part of the controller you can fit a maximum of 4 of the solar panels 100 watts per panel. Our
standard fitment is 3 solar panels. There is no “ON “or “OFF” switch on the IDC 25.
The IDC25 also has battery temperature monitoring so that the correct charge rate can be matched to
the battery temperature. It has a LED array that is easily understood, the system is protected by an
external 60amp fuse marked "Anderson".
The projector IDC 25 is designed for modern vehicles fitted with “SMART” alternators but will
work just as well with older vehicles. The only thing necessary for cars fitted with “SMART”
alternators is that the blue (ignition) wire from the controller needs to go to pin 12 (auxiliary) on
the 12 pin plug. This is something you should have previously organized with your local Auto
Electrician.
All caravans will soon be fitted with the 12 pin plug as standard. Pin 11 is wired to the
breakaway battery for in car monitoring of breakaway battery voltage (NSW requirement only)
and pin 12 the IDC25 ignition on wire.
Vehicles in states where the battery monitoring is not required and they don’t have smart
alternators fitted to their vehicles will not require their vehicle to have these features wired into
their vehicles.
