Installation and Operating Manual
Charging Converter,
B2B Battery to Battery,
Optimal Battery Charging During Driving:
VCC 1212-30
Input Voltage 12 V
Charging Capacity 12 V / 30 A
No. 3324
Please read the mounting instructions and the operating manual including the safety
instructions carefully.
Particularly observe page 15 "Safety Regulations and Appropriate Application",
prior to starting connection and start-up.
Fully automatic Battery Charging Converter for special purpose vehicles, high-quality campers, boats.
The charging converter (
booster
) of series "VCC" ensures optimum charging of the supply battery (BOARD battery) in the
living area during driving.
Four (4)
adjustable IU1oU2
charging programs
for conventional
lead-acid, gel, AGM batteries
as
well as advanced
LiFePO4
batteries ensure unattended, quick and gentle full charging from any charging state with
subsequent trickle charging of the battery.
The power for the charging converter is supplied by the vehicle's starter circuit (generator with STARTER battery). There is
no intervention into the starter circuit itself. The unit acts like a powerful load at the generator. The automatic power
control gives the required safety and ensures the vehicle's starting ability.
Depending on the driving condition, the voltage of modern
EURO standard 6, 6 + plus-
vehicles with energy-saving,
intelligent generators fluctuates considerably (12.6 V … 15.5 V). These fluctuations are handled by the charging converter to
ensure uniform charging of the BOARD battery and protection of the 12 V loads.
Due to the high charging currents, which are now possible, considerably shorter charging times and fully charged batteries
are achieved, even with conventional generators and long connection cables.
The efficient charging converter ensures high charging capacity, even with short driving distances.
Full charging when driving longer distances.
It regulates the voltage to the level, which is required for precise charging of the BOARD battery with the optimum
charging characteristic line.
The charging converter excels with its compact design, low weight (high-frequency switch mode boost and buck
converter technology) and powerfully dimensioned power components for safe operation.
The simultaneously supplied 12 V loads are protected against overvoltage and voltage fluctuations.
The integrated recharging branch 12 V / 0 ... 1 A provides charging/trickle charging of the 12 V STARTER battery in case
of extended inactivity. This recharging branch is activated automatically when the BOARD battery is being charged
externally via a battery charger.
Further Characteristics of the Unit:
The
charging voltage
is
free from spikes
and is
controlled
in such a way, that
overcharging
of the batteries is
excluded
.
Fully Automatic Operation:
The unit is permanently connected to the batteries, and it is automatically activated when
the generator of the vehicle is running. Battery discharge in case of an engine stop
is avoided
.
Charging aid for deeply discharged lead batteries or switched off LiFePO4 batteries:
Gentle preliminary charging of the
(lead-acid, gel, AGM) battery or automatic reactivation of the LiFePO4 battery, in case of possibly switched-on loads.
Parallel and Buffer Operation:
If a load is present while charging, the battery will either continue to be charged or
maintained via trickle charging. The charging time is automatically corrected and monitored by the unit.
Unattended Charging:
The unit protects against overload, overheating, overvoltage, short circuit, incorrect behaviour
and reverse current from BOARD battery by controlling the output voltage/current or in extreme cases disconnecting
the BOARD battery.
Integrated Vehicle Power Supply Filter:
Unproblematic parallel operation of charging sources (EBL, chargers, motor-
driven and petrol-driven generators, solar systems) on one battery.
Charging Cable Compensation:
Automatic compensation of voltage losses on the charging cables.
Connection for
Battery Temperature Sensor
(Sensor 825 included in the standard delivery scope):
Lead
batteries (acid, gel, AGM): In case of
low outside temperatures
, full charging of the weak battery is
improved
by
automatically correcting the charging voltage based on the battery temperature, and in case of summery temperatures
unnecessary battery gassing
and
battery load
will be avoided.
LiFePO4
Batteries: Battery protection in case of high temperatures and particularly in case of low temperatures below
0 °C.
