Votronic 40A-24V Battery Charger Pb 2440 SMT 2B - 6250

Votronic 40A-12V Battery Charger PB2440 SMT2B

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 state of the art. Their high-quality charging technology and robust power electronics, combined with intelligent microprocessor control, ensure exact adherence to 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:

• 40A main charging / 2A auxiliary charging
• Charging programs 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 preventing overcharging
• Fully automatic continuous operation for constant battery readiness
• Separate auxiliary charging output "S" for support 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
• Intelligent microprocessor control takes into account the simultaneous supply of consumers connected to the battery
• Precise battery temperature compensation (temperature sensor required)

Selectable charging programs / charging curves:

1. "Gel": Charging program for gel batteries, IU1oU2 curve

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". Also recommended for EXIDE MAXXIMA, high-current battery in AGM winding technology.

2. "AGM": Charging program for AGM / fleece batteries, IU1oU2 curve

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

3. "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, traction, lighting, solar, and heavy-duty batteries.
