Votronic 40A-12V Battery Charger Pb 1240 SMT 3B - 3124

Votronic 40A-12V Battery Charger PB1240 SMT2B for Lithium and Lead-Acid Batteries

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

Votronic chargers are characterized by high operational safety and readiness, representing the latest state of the art. Their high-quality charging technology, robust power electronics combined with intelligent microprocessor control ensure precise adherence to charging voltages, currents and times, thus extending battery life. A variety of different versions of the devices are available. This ensures that the right charger can be found 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 then for trickle charging of the battery, with temperature compensation adapted to the battery type when a temperature sensor is used. The power supply to connected consumers is also handled during charging, dimensioned so 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 the batteries being discharged.

Further special features at a glance:

• 40 A main charge / 4 A secondary charge
• Charging programs Gel, AGM, Acid, LiFePO4 (No. 1, 2, 4 and Li) adjustable to battery type
• two charging current outputs and one secondary charging output
• second main charging output can also be used for fast charging of the starter battery
• Silent-Run function adjustable (night reduction)
• Battery disconnection in case of power failure, overheating, malfunction
• Charging voltages free of peaks, thus overcharging excluded
• Fully automatic continuous operation for constant battery readiness
• Separate secondary 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 precise 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 considers the simultaneous power supply to consumers on the battery
• Precise battery temperature compensation (temperature sensor required)
• Power supply function: Allows power supply to consumers without a battery (e.g. battery change)

Selectable charging programs / charging curves:

"LiFePO4": Charging program specially for lithium batteries

Charging program specifically designed for Lithium LiFePo4 batteries with their own BMS and prescribed or built-in protection circuitry. A special quiescent maintenance automatically keeps the LiFePO4 battery at a charge level of 50-80% which is advantageous for its lifespan when the vehicle is parked (seasonal operation) and also buffers 12V consumers as well as 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

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

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 adjusted hold 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 of acid batteries in vehicles (mixed mobile/stationary). Offers short charging times, a good charge factor and good acid mixing with a medium U1 level 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.
