Votronic Pb 1280 SMT 2B Installation And Operating Manual

Installation and Operating Manual
Automatic Charger Pb 1280 SMT 2B
Automatic Charger Pb 2440 SMT 2B
Please read the mounting instructions and operating manual including the safety
regulations completely prior to starting connection and start-up.
If not connected to the battery the units will not supply any voltage (protection against
wrong polarization, safety relay, minimum battery voltage 1.0 V)!
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 Ports and Charging Programs:
Main charging port "A", depending on the type of battery, 3 charging programs selectable (see table 3):
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 with indication of the
charging voltage "14.4 V"
2. Charging Port Battery "Start":
For support charging and trickle charging of the vehicle's starter battery with separate charging control.
Operating Instructions:
The charging voltage being free from peaks 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 batteries, thus keeping
the full charge. Battery discharge in case of power failure is avoided (safety relay).
Silent Run Function: Noise-optimised operation (night operation).
Battery regeneration in case of extended stop periods: automatically twice a week to avoid harmful acid
accumulation.
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. Sensitive consumers are protected by overvoltage protection at any charging state.
Unattended Charging: Multiple protection against overload, overheating, overvoltage, short circuit, reverse
battery, excess temperature of the battery, incorrect behaviour and back discharge of battery by electronically
controlled gradual reduction down to complete separation of charger and battery by integrated safety relays.
Charging Cable Compensation: Automatic compensation of voltage loss on the charging cables. Measurement
of the voltage is to be effected at the battery and never at the charger (loss at the charging cable).
Charging aid for totally discharged batteries: Gentle preliminary charging of the battery to 8 V (16 V), followed
by powerful support of the battery, if consumers should still be switched-on.
Integrated On-board Mains Suppression Filter: Unproblematic parallel operation of solar systems, dynamos,
generators etc.
Temperature Compensation: The external temperature sensors effect an automatic adaptation of the charging
voltage rates to the battery temperature. In case of low outside temperatures, full charging of the weaker battery
is improved, and in case of summery temperatures unnecessary battery gassing will be avoided. This is highly
recommended, if the battery is exposed to strong variations in temperature, e. g. in the motor compartment.
