CTEK D250SE Dual DC-DC 20A 12V Battery Charger Caravan Battery Management System
The CTEK D250SE Dual charger is the ultimate dual battery and dual energy management system for lead acid batteries found in motorhomes, buses, campervans or even dual battery installations in standard 4WD’s. Providing two DC inputs and obtaining its power from either an alternators, solar panel, wind power or other DC energy. The D250SE automatically selects the best connected DC energy source from its two inputs and provides CTEK’s state of the art 5 stage charging process to the connected battery.
Ideally suited for caravans or motor homes with solar panels. Leaving CTEK D250SE to determine the best available energy and maintain and charge the house batteries. Charging automatically starts as soon as DC energy is provided to the charger, such as from alternators when a vehicle is started or from solar panels when connected. The D250SE has a temperature sensor which ensures optimal charging voltages at all temperatures.
With its integrated solar charge regulator, no external solar regulator is required. Simple connect a suitable solar panel and the D250SE will manage this power along with all power sources. Efficiently all batteries in the system.
The D250SE is a fully automatic 5-stage charger that supplies up to 20a to 12v batteries of 40-300Ahr. The charger is IP65 classified, which is water jet and dust protected and approved for outdoor use. The D250SE protects vehicle electronics and is suitable for all types of lead-acid batteries (Wet, MF, Gel, AGM ands LiFePO4).
