Votronic 50A-12V Battery Charger Pb 1250 SMT 3B - 3125
Votronic 50A-12V Battery Charger PB1250 SMT2B for Charging 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, thus 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 these 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 vessels! Quality Made in Germany!
All charging programs are applied by the charger for gentle full charging and then for trickle charging the battery, also with temperature compensation adapted to the battery type when a temperature sensor is used. The power supply to connected consumers is taken over during charging, dimensioned in such a way that no more than 50% flows to 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:
- 50 A main charge / 4 A auxiliary charge
- Charging programs for Gel, AGM, Acid, LiFePO4 (No. 1, 2, 4 and Li) adjustable to battery type
- Two main charging outputs and one auxiliary 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
- Charge voltages free of peaks, thus overcharging is excluded
- Fully automatic continuous operation for constant readiness of the batteries
- Separate auxiliary charging output "S" for supporting and trickle charging the vehicle starter battery, max. 2A
- Automatic battery regeneration during long downtimes (twice a week)
- Compensation for voltage losses on the charging cables for precise adherence to charging voltages
- Built-in on-board power 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 power supply to consumers without a battery (e.g., battery replacement)
Selectable charging programs / charging characteristics:
"LiFePO4": Charging program specifically for lithium batteries
Charging program optimized for Lithium-LiFePO4 batteries with their own BMS and prescribed or integrated protective circuitry. A special resting maintenance automatically keeps the LiFePO4 battery at a charge level of 50-80% beneficial for its lifespan in parked vehicles (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 in 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). With a medium U1 level, it still offers short charging times, good charge factor, and good acid mixing 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.
