VOTRONIC VCC 1212-45 IUoU-Li Isolated 12V 45A B2B Charger

1. Увод

The VOTRONIC VCC 1212-45 is an isolated B2B (Battery-to-Battery) charge booster designed for universal use. It ensures optimal and rapid charging of your leisure battery from the alternator while driving. This device supports various battery technologies, including classic lead-acid, lead-gel, lead-AGM, and modern LiFePO4 lithium batteries, offering selectable charging programs for unsupervised, fast, and gentle full charging from any state of charge.

Unlike simple cut-off relays, the VCC 1212-45 increases the charging voltage to the precise level required by each battery type, as specified by manufacturers, ensuring a complete charge. It effectively compensates for long charging cable losses and alternator voltage fluctuations, common in modern vehicles (e.g., Euro 6 with intelligent alternators). The intelligent microprocessor-controlled charging with IU1oU2oU3 characteristic curves and dynamic charging time calculation guarantees a quick, gentle, and full charge, maintaining the charge of connected batteries while simultaneously supplying power to 12V consumers.

2. Безбедносна упутства

• Read this manual completely before installation and operation.
• Installation must be performed by qualified personnel in accordance with all applicable safety standards and regulations.
• Ensure all connections are secure and correctly polarized to prevent damage to the device or batteries.
• Always disconnect the power supply before performing any installation, maintenance, or troubleshooting.
• Не отварајте уређај цasinг. Унутра нема делова које корисник може сам да поправи.
• Keep the device away from moisture, extreme temperatures, and flammable materials.
• Ensure adequate ventilation around the charger to prevent overheating.
• Use appropriate fuses as specified in the wiring diagram to protect the cables and the device.

3. Подешавање и инсталација

3.1. Физичка инсталација

The VCC 1212-45 features a compact design and low weight due to high-frequency switching technology. Mount the unit in a dry, well-ventilated area, ensuring the rubber feet for vibration reduction are not removed. These feet are crucial for the device's longevity and performance.

3.2. Dijagram ožičenja

Refer to the diagram below for correct wiring. All fuses should be connected as directly as possible to the batteries for optimal cable protection.

Figure 1: General Connection Diagram for Votronic VCC 1212-45 Charger

• Battery II IN (Start): Connects to the Start Battery.
• Battery I OUT (Leisure): Connects to the Leisure Battery.
• D+ or Terminal 15: This signal must be connected for the charger to activate.
• Sense In + (Start) / Terminal 15/D+: Connect these small wires (0.5-1.5 mm²) to the respective terminals. Strip cable ends by 10 mm.
• Sense Out + (Leisure): Connect this small wire (0.5-1.5 mm²) to the leisure battery positive terminal. Strip cable ends by 10 mm.
• Осигурачи:
• Fuse II (Start Battery): 30 A - 80 A.
• Fuse I (Leisure Battery): 30 A / 50 A.
• Small Fuses: 3 A for sense lines.
• Цхассис Гроунд: Connect both start and leisure batteries to chassis ground.
• Инпут/Оутпут Волtage: The charger supports 12V input to 12V output, or 24V input to 12V output.

3.3. Избор типа батерије

Користите Slide switch Battery-Type on the unit to select the appropriate charging program for your leisure battery (Lead-Acid, Lead-Gel, Lead-AGM, or LiFePO4). Refer to the device's labeling for specific switch positions.

3.4. Temperature Sensor Connection

Connect the supplied temperature sensor to the designated port on the charger. For LiFePO4 batteries, mount the temperature sensor on the negative terminal of the battery. This allows for automatic adaptation of charging voltage to battery temperature, optimizing charging efficiency and preventing unnecessary gassing in lead batteries, and protecting LiFePO4 batteries at low temperatures (below 0°C).

4. Операција

4.1. Аутоматски рад

The VCC 1212-45 operates fully automatically. Once connected, the device is activated by the alternator when the vehicle engine is running. When the engine is off, the batteries are not discharged. The charger continuously charges or maintains the battery even with simultaneous consumption, with charging times automatically calculated and monitored by the device.

4.2. Charging Characteristics

• Волtagе Регулатива: Тхе цхаргинг волtage is free of spikes and regulated to prevent battery overcharging.
• Line Loss Compensation: The device fully compensates for line losses and alternator voltage fluctuations, ensuring stable charging.
• 12V Consumer Protection: Connected 12V consumers are protected against overvoltagес и волtagе флуктуације.
• Deeply Discharged Lead Batteries: Supports gentle pre-charging of deeply discharged lead batteries up to 8V, then provides powerful support even with active consumers.

4.3. Заштитне карактеристике

The VCC 1212-45 offers multiple protections for unsupervised charging:

• Заштита од преоптерећења
• Заштита од прегревања
• Оверволtagе заштита
• Заштита од кратког споја
• Incorrect behavior protection
• Battery discharge protection (electronic regulation up to complete separation of the device and battery)

Parallel operation with other charging sources on a single battery is possible without issues.

5. Одржавање

The VOTRONIC VCC 1212-45 charger is designed for maintenance-free operation. To ensure optimal performance and longevity, consider the following:

• Редовна инспекција: Periodically check all cable connections for tightness and corrosion. Ensure fuses are intact.
• Чишћење: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
• Вентилација: Ensure that the ventilation openings are not obstructed to allow for proper heat dissipation.
• Услови животне средине: Operate the device within its specified temperature and humidity ranges.
