The TBooster PRO 1245 is the ideal DC/DC converter for optimising the charging of 12V batteries while driving. Thanks to step-up/down technology, this device compensates for the voltage of the alternator, making it suitable for every phase of battery charging. Essential for EURO6 vehicles, where the energy-saving strategy makes the alternator voltage variable depending on the driving conditions, it is also particularly suitable for conventional alternators, as it ensures a full and more efficient charge, especially in systems with particularly long lines.
