D250SE is a fully automatic five-phase charger that produces up to 20 A current for lead-acid type and lithium* type 12 V drive batteries (40?300 Ah). The user can select the charging algorithm for AGM or lithium* batteries, and dual feed is available for chargers and solar and wind power. When the drive battery is fully charged, the D250SE automatically switches to maintenance charging of the starter battery. The D250SE is capable of maintaining a stable output current of up to 20 amps for vehicles equipped with an ECU-controlled alternator and a temperature sensor that optimizes charging regardless of weather conditions.
