Votronic 15A-12V Battery Charger Pb 1215 SMT 2B - 3100

Votronic 15A-12V Battery Charger PB1215 SMT2B for Lead-Acid and Lithium Batteries

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

Votronic chargers are characterized by high operational reliability and high availability, thus representing the latest state of the art. Their high-quality charging technology, robust power electronics, and intelligent microprocessor control ensure exact adherence to charging voltages, currents, and times, thus ensuring 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 used by the charger for gentle full charging and subsequent battery maintenance charging. When a temperature sensor is used, temperature compensation corresponding to the battery type is also applied. The power 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 full, almost the entire possible device charging current is available for the consumers, without the batteries being discharged.

Other special features at a glance:

• 15A main charging / 2A auxiliary charging
• Charging programs Gel, AGM, Acid, LiFePO4 (No. 1, 2, 4 and Li ) selectable by battery type
• 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 excluding 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 adherence to 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 curves:

"LiFePO4": charging program specifically for lithium batteries

Charging program tailored to lithium-LiFePO4 batteries with their own BMS and mandatory or built-in protection circuitry. A special standby maintenance keeps the LiFePO4 battery at an advantageous charge level of 50-80% for its service life when the vehicle is parked (seasonal operation) and also buffers 12 V consumers as well as the vehicle starter battery. In addition, a regular Auto Wake Up function activates the battery cell balancing.

1. Gel: charging program for gel batteries, IU1oU2oU3 curve

Tailored to 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". Perfectly suited for charging WATT-HOUR GEL batteries.

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

Designed for charging sealed, gas-tight AGM (Absorbent-Glass-Mat) batteries and those in lead-mat technology, 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, IU1oU2oU3 curve

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, drive, lighting, solar, and heavy-duty batteries, as well as AGM batteries with normal U1 levels.
