The CTEK D250S DUAL is a fully automatic 5-stage charger that supplies 20A to 12V batteries of 40-300Ah.
IP65 classified (water jet and dust protected and approved for outdoor use), protects vehicle electronics and is suitable for all types of lead-acid batteries (Wet, MF, Gel, AGM).
This versatile charger obtains its energy from DC sources such as:
Charging will 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 D250S DUAL automatically selects the best connected DC energy source (of 2) for the purpose and switches between these energy sources to achieve high efficiency multi-stage charging. CThe D250S DUAL has a temperature sensor which ensures optimal charging voltages at all temperatures. The D250S DUAL ensures that your batteries are always in good condition, quick charging and long battery lifetimes.
