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, 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 provide an additional 2a charging current. The device is suitable for batteries with a capacity of 150 Ah - 880 Ah.

important features of the Pb 1280 smt 2b battery charger

• charges reliably gel, agm and lead-acid
• 80A charge current, 4a charge current at secondary charge output
• official Votronic part number: 3131
• Battery capacity (recommended): 150 Ah - 880 Ah
• Charging capabilities: The Pb 1280 smt 2b charges: one supply battery and one starter battery.
• Excellent charging technology
• Charging voltages are free of peaks and regulated to eliminate overcharging
• Fully automatic continuous operation for constant readiness for use of the batteries
• Precise battery temperature compensation (temperature sensor part no. 2001 required)
• Separate auxiliary charge output "S" for support and maintenance charging of the vehicle starter battery, max. 2a
• Automatic battery regeneration during long idle periods (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 co-powering of consumers on the battery
• Disconnection of the batteries in case of mains failure, overheating, malfunction (safety switch per charging output)
• Silent-run function adjustable (night setback)
• Battery capacity adjustable 4 times (total of 12 charging programs)
• Inputs for voltage sensor (sense) lines, optionally usable with overlong charging lines and/or external, lossy diode charging current distributors
• Mains/charging power can be reduced in case of low-power or limited mains supply, e.g. weakly fused shore power, generator operation, etc. (power limit function)

overview of the charging programs of the Pb 1280 smt 2b

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

"agm": charging program for agm/fleece batteries, characteristic IU1oU2oU3?Intended 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 retention (plate and round cell technology). .

"UNIVERSAL": charging program for lead-acid/wet/agm batteries, characteristic IU1oU2oU3?universal program for charging and charge retention of acid batteries in vehicles (mixed mobile/stationary). With medium U1 level, still provides short charge times, good charge factor and good acid mixing for open and closed, low maintenance, maintenance free standard, traction, lighting, solar and heavy duty batteries, as well as agm batteries with normal U1 level. .
