Booster WA 121545 45/70 A (motorhome)

The booster WA 121525 is a timed upward/ downward converter with a high efficiency, balancing the volatile light machine voltage and providing a high charging current. It serves to charge lead-acid, lead-gel, AGM, and Lithium batteries perfectly while driving with 12 V mains power. If a battery temperature sensor is connected, the charging voltages are adapted to the battery’s temperature. For perfect charging, not only is the living area battery’s voltage measured, but also the starter battery’s. Scope of delivery: all accessories except the connection cables.

Charging characteristics curve: IUoU (power-independent switch to charge retention)

Configurable battery types:

• Lead-acid battery: 14.4 V / 13.4 V
• Lead-gel battery: 14.4 V / 13.8 V
• AGM1 battery: 14.4 V / 13.8 V
• AGM2 battery: 14.7 V / 13.7 V
• Lithium battery: 14.4 V constant (CCCV or IU characteristics curve for LiFePO4 batteries with an autonomous battery management system

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

Energy conversion efficiency: ≥ 93 % at maximum charging current
