Quick fact

When using an energy-saving charging alternator (Euro 6), using a booster is required because the charging voltage fluctuates very strongly (12,6V to 15V). When using a conventional alternator, the living area battery charge can be improved by using a booster.
Charges 12V lead-acid, lead-gel, AGM, and lithium batteries while driving, regardless of alternator voltage
Selectable characteristic curves can be any combination of lead-acid, lead-gel, AGM I, AGM II, lithium (CCCV)
Charging characteristic curve: IUoU (current-dependent switchover to trickle charge)
Bypass switch to facilitate starter battery charging when the connected electroblock is in grid mode
Adjustable / curve-controlled charging current limitation / power limitation
Charging current temperature compensation
Current is adjustable in four increments: 45 A, 55 A, 63 A, and 70 A
Overheating protection
D+ controlled
