CTEK D250S Dual - 12V 20A Battery to Battery Charger
The D250S DUAL charger takes power from DC sources such as alternators, solar panels or wind turbines and optimises this power to meet the charging requirements of different battery banks.
The D250S DUAL automatically selects the best connected DC energy source for the purpose and switches between these energy sources to achieve high efficiency multi-stage charging.
The D250S DUAL is particularly suitable for charging vehicles that do not have access to grid power supplies. Charging automatically starts as soon as DC energy is provided to the charger, for example from alternators when a vehicle is started or from solar panels when connected.
The D250S DUAL ensures your batteries are always in good condition and help prolong their lifespan.

Maintenance charge of starter battery
Solar panel regulator with Maximum Power Point Tracking, synchronised with other current sources such as the alternator and/or wind
Simplified installation of remote batteries for bow thrust of anchor winch
BENEFITS
Maximised battery life due to minimised undercharge time
Maximised battery capacity when the battery is kept fully charged to avoid harmful sulphate crystals on the lead plates and stratification of the battery acid.
Ability to take charge automatically from any power source that is connected to the D250S DUAL
Reduced charging times and costs by decreasing engine idling and the dependency on AC power onshore through efficient use of alternator and solar power
Reduced environmental impact through extended battery life and a reduced idle time
Minimal installation time and cost
SUITABLE FOR
Boats
Campervans and RVs
Caravans
4WDs
Housing that rely on generators for extra electricity
D250S DUAL is a 5-step charger that automatically adjusts the charging voltage and current according to the battery state of charge and temperature–reducing a battery’s charge time.
A sensor on the CTEK charger senses the battery temperature and adjusts the required charge by increasing the voltage in cold weather ensuring the battery is fully charged, and dropping the voltage in hot weather to avoid the problems of overcharging.
With the D250S DUAL, vehicle owners can be confident that their battery will always receive the optimal charging voltage, with reduced charge time and while ensuring the charging will be 100% complete.
SOLAR CONNECTION
The D250S DUAL has the additional benefit of an auxiliary input which can be connected directly to solar panels without the need for a regulator, offering free power from the sun.
D250S DUAL has a built-in Maximum Power Point Tracker (MPPT) that helps the solar cells produce power as efficiently as possible by taking the most efficient source of energy from the solar panels automatically, and then using the power to charge the battery.
The MPPT searches for the most effective combination of solar cell voltage and current, which ensures that the solar and alternator function in unison to maximise power output.
Protections
No harmful galvanic currents - CTEK M200 produces no harmful galvanic currents that cause corrosion which quickly damages various metal components under the boat, including propellers and ladders
Application
The CTEK D250S Dual 12V 6 Stage Charger is suitable for Boats, campervancs & RV’s, caravans, 4WD & housing that rely on generators for extra electricity.
