Votronic 3131 Pb 1280 SMT 2B 12V 80A battery charger

The Automatic Charger Pb 1280 SMT 2B from Votronic (MPN 3131) is a modern battery charger for mobile use. It has charging programs for GEL, AGM, and lead-acid batteries and is designed for 12V battery voltage. The charging current at the main output is 80A. In addition, there is a secondary charging output for the starter battery, which can supply an additional 2A charging current. The device is suitable for batteries with a capacity of 150 Ah - 880 Ah.

key features of the Pb 1280 SMT 2B battery charger

• reliably charges GEL, AGM, and lead-acid batteries
• 80A charging current, 4A charging current at the secondary charging output
• official Votronic part number: 3131
• Battery capacity (recommended): 150 Ah - 880 Ah
• Charging options: The Pb 1280 SMT 2B charges: one supply battery and one starter battery.
• Excellent charging technology
• The charging voltages are free of peaks and regulated in such a way that overcharging is impossible
• Fully automatic continuous operation for constant battery readiness
• Precise battery temperature compensation (temperature sensor item no. 2001 required)
• Separate auxiliary charging output "S" for support and maintenance charging of the vehicle starter battery, max. 2A
• Automatic battery regeneration during long periods of inactivity (twice a week)
• Compensation of voltage losses on the charging cables for exact compliance with the charging voltages
• Intelligent microprocessor control takes into account the simultaneous supply of consumers from the battery
• Disconnection of batteries in the event of power failure, overheating, malfunction (safety switch per charging output)
• Silent run function adjustable (night reduction)
• Battery capacity 4-fold adjustable (12 charging programs in total)
• Inputs for voltage sensor (Sense) cables, optionally usable with excessively long charging cables and/or external, lossy diode charging current distributors
• Mains/charging power can be reduced in the event of low-power or restricted mains supply, e.g., weakly fused shore power supply, generator operation, etc. (power limit function)

overview of the charging programs of the Pb 1280 SMT 2B

"Gel": Charging program for gel batteries, characteristic curve IU1oU2oU3?Designed for sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times in order to achieve short charging times with particularly high capacity storage and to prevent long-term battery "starvation."Starvation.

"AGM": Charging program for AGM/fleece batteries, characteristic curve IU1oU2oU3? Designed for charging sealed, gas-tight AGM (Absorbent Glass Mat) batteries in lead-fleece technology, which require a particularly high U1 level with coordinated holding times for full charging and then a moderate U2 level for charge maintenance (plate and round cell technology).

"UNIVERSAL": Charging program for lead-acid/wet/AGM batteries, characteristic curve IU1oU2oU3? Universal program for charging and charge maintenance of acid batteries in vehicles (mixed mobile/stationary). With a medium U1 level, it still offers short charging times, a good charging factor, and good acid mixing for open and closed, low-maintenance, maintenance-free standard, drive, lighting, solar, and heavy-duty batteries, as well as AGM batteries with a normal U1 level.
