20 A dual input 20 A charger with selectable charging voltage

More pleasure and serenity

With its award-winning Swedish technology, the D250SE Dual Input allows you to get more out of your vehicle, with optimised battery capacity: it's the ideal charger for vehicles without access to an AC power source.

The D250SE is a fully automatic 5-step charger that delivers 20A of power to any 12V lead acid or lithium* service battery from 40-300 Ah. It has selectable charging algorithms for AGM and lithium* batteries and can use energy from its dual input from the alternator, solar panel and wind power. When the service battery is fully charged, the D250SE automatically transfers the maintenance charge to the starter battery. The D250SE maintains a stable power supply of up to 20 A for vehicles equipped with intelligent ECU-controlled alternators, and has a temperature sensor to ensure optimum charging in all weather conditions. *) 12 V Lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
