Intelligent charging booster for all 12 V vehicle and solar batteries. The IVT charging booster is designed to charge lead-acid, lead-gel, AGM, and lithium secondary batteries while driving in vehicles with 12 V systems. This versatile charging booster features two charging levels. In the 30 A mode, the secondary battery can be charged with up to 30 A. In the 10 A caravan mode, the charging booster allows batteries in a caravan or trailer to be charged via the plug connection. In this mode, the charging current is limited to a maximum of 10 A. The intelligent IVT charging booster is a switched buck-boost converter that stabilizes the fluctuating alternator voltage. Once an alternator signal is present at the charging booster (D+), it automatically activates. The connected secondary battery is charged independently of the alternator voltage. The switch to maintenance charging occurs automatically and based on current. Note: Additional consumers should only be connected to the secondary battery.
