NOTE: The values being indicated in parentheses ( ) apply to 24 V operation.
All-automatic battery charger with 2 charging ports for intervention vehicles, special-purpose
vehicles, special high-quality campers, as well as marine application.
VOTRONIC chargers of series “PB SMT” are of compact design and have only a low weight (high frequency
switching power supply, switch mode technology). They distinguish by full charging capacity, even in case of large
deviations of the power supply (low voltage/overvoltage, sine curve, frequency).
The intelligent microprocessor charging control with characteristic lines of charging „IU1oU2“ and dynamic
calculation of the charging time automatically ensures quick and careful full charging followed by 100 % trickle
charging of the connected batteries from any charging state, allowing always simultaneous supply of 12 V (24 V)
consumers being connected in parallel or charging of very large batteries (depending on the case of application).
Battery outputs and Charging Programs:
Main output Battery I, depending on the type of battery, 3 charging programs selectable (see table 1):
a)
„AGM“:
Closed, gas-tight
AGM/fleece
batteries VRLA (lead-fleece technology)
“14.8 V”
b)
„Gel“:
Closed, gas-tight
Gel/dryfit
batteries VRLA (determined electrolyte)
c)
„Lead Acid“:
Closed and open
acid/lead-acid
batteries, as well as
AGM 14.4 V
Second output Battery II:
Separate auxiliary charging output with reduced charging current 12 V (24 V) / 2 A for support charging and
conservation of charge of the vehicle’s starter battery with overcharge protection.
Further Characteristics of the Unit:
The
charging voltage
is
free from peaks
and is
controlled
in such a way, that any
overcharging
of the
batteries is
excluded
.
All-automatic Continuous Operation:
The charger may be connected continuously to the battery, thus
keeping the full charge. Battery discharge in case of power failure
is avoided
(
separation by safety switch
).
Battery regeneration in case of extended stop periods
: twice a week to avoid harmful acid accumulation.
Silent Run Function:
Noise optimised operation (night operation) at the touch of a button.
Parallel and Floating Operation:
In case of simultaneous consumption, charging of the battery is continued or
the charge will be conserved fully. Calculation and control of the adaptation of the charging time is effected
automatically by the charger.
Unattended Charging:
Multiple protection against overload, overheating, overvoltage, short circuit, wrong
polarization, incorrect behaviour and back discharge of the battery by electronically controlled gradual
reduction down to complete separation of charger and battery
by integrated safety switch.
Power Supply Function:
Allows supply of the consumers without battery (e. g. replacement of battery)
Charging Cable Compensation:
Automatic compensation of voltage loss on the charging cables.
Charging aid for totally discharged batteries:
Gentle preliminary charging of the battery from 0 V to 8 V
(16 V), followed by powerful support of the battery, should consumers be still switched-on.
Integrated On-board Mains Suppression Filter:
Unproblematic parallel operation of solar systems, wind and
petrol-driven generators, dynamos etc. at one battery.
Temperature Compensation:
In case of
low outside temperatures
,
full charging
of the weak battery
is
improved
by automatic adaptation of the charging voltage to the battery temperature, and in case of summery
temperatures
unnecessary battery stress and gassing
will be avoided. Temperature Sensor, Order No. 2001,
is required.
