Dual input 20A charger with selectable charge voltages
The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead-acid or lithium* service battery from 40–300Ah. It has selectable charge algorithms for AGM and lithium* batteries and can use power through its dual input from alternator and solar panel. When the service battery is fully charged, the D250SE will automatically redirect maintenance charge power to the starter battery. The D250SE 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. *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
FEATURES 20A fully automatic temperature compensated charging for batteries from 40-300Ah while you’re on the move Dual input (solar and alternator in parallel) Smart alternator compatible Selectable lithium* and lead-acid mode Solar panel regulator with Maximum Power Point Tracking (MPPT) Battery separation replacing diodes and VSR relays Selectable AGM option – 14.4V or 14.7V Maximised charging for better battery life and performance Temperature sensor to compensate for hot or cold conditions Splash and dust proof (IP65) Compatible with SMARTPASS 120, SMARTPASS 120S for the ultimate 140A power management solution
