Description

The DC battery chargers of the VBS series are one of the most effective ways to charge the 12V main or auxiliary battery of the vehicle via the alternator or a 24V or a 12V starter battery or optionally via solar power. They are compatible with a wide range of alternator types and provide correct charging voltages for AGM, gel, deep-cycle and even LiFePO4 batteries.

When interrupting a journey or arriving at a destination, solar charging starts automatically via the solar modules on the vehicle roof.

Compact design and easy to install; IP66, resistant to dust, water, shocks, and extreme temperatures from -20°C to 80°C, enables use in motorhomes, commercial vehicles, boats, yachts and many other applications.

The charging boosters are fanless and noiseless, have a compact size and are equipped with a three-stage charger and several electronic protection devices.

Features

• 40A Solar MPPT
• 40A charge booster
• Feed-in from solar and alternator
• Efficiency up to 95
• Excellent performance in harsh environments
• IP66, resistant to dust, water and shocks
• Compatible with Euro6 alternators
• Safety precautions such as undervoltage, overvoltage, overtemperature and reverse polarity

Charging process in three steps:

• Step 1: Maximum current up to the target value of the constant voltage charge
• Step 2: Current decreases, constant voltage charging mode starts
• Step 3: Stop constant voltage charging at the corresponding battery voltage and start trickle charging

Installation of the Voltima charge booster

The battery technology is selected via a button: Lithium or lead-acid/AGM/gel. The connection for the Voltima VBS remote control is located on the battery booster. A monitor that informs the user about the current battery charge level, among other things (not included, available separately, see "Accessories").

Further connections, for example for a voltage measurement cable and temperature sensor, are also available.

Alternator as generator

The vehicle alternator works like an electric generator, which is driven by the combustion engine to charge the starter battery and consumer devices. When the starter battery is finally charged depends on its initial state of charge and the duration of the journey. If the battery is full, it can no longer hold any reserves. This is where the Voltima VBS charging booster comes in handy. It takes over the energy thatis still being generated and stores it in an additional battery.

Loss-free charging

For optimum battery charging, the Voltima VBS charging booster automatically adjusts the voltage measurement cables to the required values via an exact charging characteristic. In doing so, it compensates for line losses and voltage fluctuations from the generator that occur while driving - both for the battery and for the 12-volt consumer devices.
