CTEK D250S Dual DC-DC Battery Charger 12V

Maximised battery life and capacity

The CTEK D250S Dual DC-DC Battery Charger obtains
its energy from DC sources such as alternators, solar panels or
wind power and optimises this power to meet the charging
requirements of different battery banks. The CTEK 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. The CTEK D250S DUAL
is particularly suitable for charging caravans, motor caravans,
boats and second homes that do not have access to grid power
supplies. 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 CTEK D250S DUAL
has a temperature sensor which ensures optimal charging voltages at
all temperatures. The CTEK D250S DUAL ensures that your batteries
are always in good condition, quick charging and long battery
lifetimes.

The CTEK D250S DUAL is a fully automatic 5-stage charger that
supplies 20A to 12V batteries of 40-300Ah. The charger is 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). It’s supplied with a 2
year guarantee.
