Votronic 25A-12V Battery Charger Pb 1225 SMT 2B - 3102

Votronic 25A-12V Battery Charger PB1225 SMT2B for Lead-Acid and Lithium Batteries

Designed for high-quality motorhomes, marine use, special vehicles, and self-sufficient applications.

Votronic chargers are characterized by high operational reliability and readiness for use, representing the latest state of the art. Their high-quality charging technology, robust power electronics in conjunction with intelligent microprocessor control, ensures precise adherence to charging voltages, currents, and times, thus extending battery life. A variety of different versions of the devices are available, allowing you to find the right charger for your application.

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

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

When batteries are full, almost the entire possible device charging current is available for consumers, without discharging the batteries.

Further special features at a glance:

• 25A main charge / 2A auxiliary charge
• Charging programs for Gel, AGM, Acid, LiFePO4 (No. 1, 2, 4 and Li) adjustable to battery type
• Excellent charging technology
• Silent-Run function adjustable (night reduction)
• Battery disconnection in case of power failure, overheating, malfunction
• Charging voltages free of peaks, thus overcharging is excluded
• Fully automatic continuous operation for constant battery readiness
• Separate auxiliary charging output "S" for support and trickle charging of the vehicle starter battery, max. 2A
• Automatic battery regeneration during long periods of inactivity (2x a week)
• Compensation of voltage losses on the charging cables for exact adherence to charging voltages
• Built-in on-board network filter: Problem-free parallel operation with solar systems, generators, alternators etc. on one battery.
• Intelligent microprocessor control takes into account the simultaneous supply of consumers on the battery
• Precise battery temperature compensation (temperature sensor required)
• Power supply function: Enables the supply of consumers without a battery (e.g. battery change)

Selectable charging programs / charging curves:

"LiFePO4": Charging program specially for lithium batteries

Charging program optimized for lithium LiFePO4 batteries with their own BMS and prescribed or built-in protection circuitry. A special quiescent charge automatically maintains the LiFePO4 battery at a charge level of 50-80% which is beneficial for its lifespan when the vehicle is parked (seasonal operation), and also buffers 12 V consumers and the vehicle's starter battery. In addition, a regular Auto Wake Up function activates battery cell balancing.

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

Optimized for sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation". Perfectly suited for our WATTSTUNDE gel batteries, among others.

2. "AGM": Charging program for AGM / fleece batteries, characteristic IU1oU2oU3

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

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

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