Product Description
The CTEK 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. This charger obtains its energy from DC sources such as alternators, solar panels or wind power and optimizes this power to meet the charging requirements of different battery banks. It 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.
A sensor on the 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.
This charger 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 and 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 maximize power output. This charger is perfect for boats with one battery, boats with start & service battery, boats with start & service bank, campervans, caravans, RV’s and trucks.
The D250S battery charger has a 5 year Limited warranty
