The 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 confi dent that their battery will always receive the optimal charging voltage, with reduced charge time and while ensuring the charging will be 100% complete.
The D250S DUAL has the additional benefi t of an auxiliary input which can be connected directly to solar panels without the need for a regulator, off ering free power from the sun.
D250S DUAL has a built-in Maximum Power Point Tracker (MPPT) that helps the solar cells produce power as effi ciently 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 eff ective combination of solar cell voltage and current, ensuring that the solar and alternator function work in unison to maximise power output.
