All-automatic battery charger with 3 charging sources for optimum battery charging during
mains operation and solar operation, designed for motor homes and intervention vehicles.
Please completely read this operating and installation manual thoroughly prior to connection and
start-up, in particular "Safety Regulations and Appropriate Application", s. page 18.
VOTRONIC chargers of series "VBCS Triple" excel by their compact design, low weight (high-frequency switching power
supply, Switch Mode Technology), as well as the intelligent microprocessor charging control with characteristic lines of
charging „IU1oU2oU3“ and dynamic charging time calculation.
8 charging programs stored in the memory for
Lead-Acid, Gel and AGM
, as well as advanced
Lithium LiFePO4 Batteries,
ensure unattended, quick and careful full charging from any charging state with subsequent trickle charging and maintenance
of the battery and simultaneous supply of the connected consumers 12 V during the entire charging process. Consumed
energy will be compensated immediately.
Mains Operation
, during standstill operation at the external socket of the mains supply:
The full charging capacity in the universal wide range from 110 V AC - 230 V AC without any switching is available
worldwide, even in case of large deviations in the power supply (low voltage/overvoltage, sine curve, frequency).
Efficient charging of the board battery and supply of the 12 V consumers via mains.
Auxiliary charging 12 V/4-5 A for support charging and trickle charging of the vehicle's (lead) starter battery in case of
extended standstill periods.
Due to the long-term characteristic lines of charging, the unit may be connected continuously to the mains (such as for
standstill periods or winter breaks).
Charging Converter, "B2B" Operation,
mobile operation from dynamo and starter battery (Battery to Battery):
The efficient charging converter (booster) allows full charging of the board battery during driving.
It increases/reduces the voltage to the level, which is required for precise charging of the board battery with the
optimum characteristic line of charging.
Cable losses and considerable voltage fluctuations of the dynamo, known from
Euro 6
vehicles, are completely
compensated.
The simultaneously supplied 12 V consumers are protected against overvoltage and voltage fluctuations.
Solar Operation, "MPP" (M
aximum-
P
ower-
P
oint
)
:
Controllers according to the MPP technology are continuously and automatically calculating the maximum power yield
(MPP) of the solar modules several times per second. This surplus of charging current of 10 % to 30 % ensures short
charging times and the best possible power yield of the solar system.
Auxiliary charging for support charging and trickle charging of the vehicle's starter battery in case of extended standstill
periods.
Terminal "AES",
for automatic commutation of refrigerators with "AES" (Automatic Energy Selector, Electrolux /
Dometic) from gas operation to 12 V operation in case of excess solar power.
Pulser Operation
, training for the board battery during the charging breaks, if a charging source is not existing:
The battery training protects the unused (lead) battery during the winter break, seasonal operation or extended standstill
periods from premature ageing and failure due to sulphation.
Further Characteristics of the Unit:
The
charging voltage
being
free from peaks
is
controlled in such a way,
that
overcharging
of the batteries
is excluded
.
All-automatic Continuous Operation:
The charger may be connected continuously to the batteries, thus keeping the full
charge. If the charging source is missing (power failure, engine stop, night), the batteries will
not be
discharged.
Parallel and Floating Operation:
In case of simultaneous consumption, charging of the battery is continued or trickle
charging is effected. Calculation and control of the adaptation of the charging times is effected automatically by the
charger.
