The battery charge booster from Carbest with 40 A power charges your on-board or secondary battery quickly and reliably while driving. The IUoU charging characteristic curve supplies the battery with constant current and voltage matched to it. Once the final charging voltage has been reached, the system switches to trickle charging. This compensates for the self-discharge of the battery. The special, integrated 18 A refrigerator output can be used to supply an absorber or compressor refrigerator with power directly from the charge booster. Integrated undervoltage and overvoltage protection and reverse polarity protection
