Votronic 80A-12V Battery Charger Pb 1280 SMT 2B - 3131

Votronic 80A-12V Battery Charger PB1280 SMT2B

Designed for high-quality motorhomes, marine applications, special-purpose vehicles, and off-grid applications.

Votronic chargers are characterized by high operational reliability and high availability, thus representing the state of the art. Their high-quality charging technology and robust power electronics, combined with intelligent microprocessor control, ensure exact compliance with charging voltages, currents, and times, and thus a long battery life. A variety of different versions of the devices are available. This makes it easy to find the right charger for your application.

Votronic charging technology has been used for years in professional emergency vehicles such as fire engines, ambulances, and coast guard vessels! Quality Made in Germany!

All charging programs are applied by the charger for gentle full charging and subsequent battery maintenance charging. When a temperature sensor is used, temperature compensation is also applied, adapted to the battery type. The supply of connected consumers is also provided during charging, dimensioned so that no more than 50% flows to the consumers during the I-phase (initial charging).

When the batteries are fully charged, almost the entire possible device charging current is available for the consumers, without the batteries being discharged.

Other special features at a glance:

• 80 A main charging / 2 A auxiliary charging
• Gel, AGM, acid (No. 1, 2, 4) charging programs selectable (separate device available for Li!)
• Excellent charging technology
• Silent-run function selectable (nighttime reduction)
• Disconnection of the batteries in the event of a power failure, overheating, or malfunction
• Charging voltages free from peaks, thus preventing overcharging
• Fully automatic continuous operation for constant battery readiness
• Separate auxiliary charging output "S" for trickle and maintenance charging of the vehicle starter battery, max. 2A
• Automatic battery regeneration during long periods of inactivity (2x per week)
• Compensation of voltage drops on the charging cables for exact compliance with charging voltages
• Built-in onboard network filter: trouble-free parallel operation with solar systems, generators, alternators, etc. on a battery.
• Intelligent microprocessor control takes into account the simultaneous supply of consumers connected to the battery
• Precise battery temperature compensation (temperature sensor required)
• Power supply function: Enables the supply of consumers without a battery (e.g., during battery replacement)

Selectable charging programs / charging characteristics:

1. "Gel": charging program for gel batteries, characteristic IU1oU2oU3

Designed for sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 maintenance times to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation". Among other things, perfectly suited for our WATTSTUNDE gel batteries.

2. "AGM": charging program for AGM / mat batteries, characteristic IU1oU2oU3

Designed for charging sealed, gas-tight AGM (Absorbent-Glass-Mat) batteries and lead-mat technology batteries, which require a particularly high U1 level with coordinated maintenance times for full charging and then a moderate U2 level for maintenance charging (round cell and plate technology).

4. "UNIVERSAL": charging program for lead-acid / wet batteries, characteristic IU1oU2oU3

Universal program for charging and maintenance charging of acid batteries in vehicles (mixed mobile/stationary). With a medium U1 level, it offers short charging times, a good charging factor, and good acid mixing for open and sealed, low-maintenance, maintenance-free standard, traction, lighting, solar, and heavy-duty batteries, as well as AGM batteries with a normal U1 level.
