The Booster WA 121525 is a clocked step-up/step-down converter with a very high level of efficiency. It balances the volatile alternator voltage and provides a high charging current. The booster is perfect for charging lead acid, lead gel, AGM1, AGM2 and lithium batteries while driving with 12 V mains power. If a battery temperature sensor is connected, the charging voltages are adapted to the battery’s temperature. To guarantee optimal charging, both the voltage of the living area battery and the voltage of the starter battery are measured with a voltage sensor. Scope of Delivery: all accessories except the connection cables.
Charging characteristic: IUoU (power-dependent switch to charge retention)
Adjustable battery types:
Temperature compensation: automatic after connecting the temperature sensor, maximum charging voltage then: 15.0 V
Input voltage range: 12.0 V – 15.0 V
Maximum charging current adjustable to four levels: 45 A/55 A/63 A/70 A
Level of efficiency: ≥ 93 % at maximum charging current
