CTEK D250SE DCDC 12V 2 input charger

CTEK D250SE DCDC 12V 2 input charger

12V | 20A dual input charger with selectable charging voltage

The D250SE is a fully automatic 5-step charger that delivers 20 A power to any 40-300 Ah 12V lead-acid or lithium* service battery. It has selectable charging algorithms for AGM and lithium batteries and can use energy thanks to 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 alternators controlled by ECU; It also has a temperature sensor to optimize loading, regardless of weather conditions. *) 12 V Lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
