Bragging premium Swedish Technology, the dual input D250SA allows for the most enjoyment out of your vehicle with maximized battery capacity. The ideal charger for vehicles without access to a mains power supply. The D250SA is a fully automatic, 5 step charger that supplies up to 350A of power to any 12V lead acid service battery from 40-300Ah, including Wet, EFB, MF, Ca/Ca, AGM and Gel. It has selectable charge voltages for AGM batteries and can use power through its dual input from alternator, solar panel and wind power. When the service battery is fully charged, the D250SA will automatically redirect maintenance charge power to the starter battery. The D250SA can maintain a stable output up to 20A to vehicles fitted with smart ECU controlled alternators and also has a temperature sensor for optimised charging, regardless of weather conditions.
