DC/DC Battery Charger

The CTEK D250S DUAL is a fully automatic 5-stage DC-DC charger that supplies 20A to 12V batteries from 40Ah - 300Ah.
The
D250S Dual
refines all DC sources including alternators and solar power, to perfectly match the amount of charge the battery requires whilst minimising charge time. The
D250S Dual
is a 20A multi-step charger that automatically adjusts the charging voltage and current according to the battery state of charge and temperature to ensure that the battery is safely optimised for performance.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.
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
D250S DUAL
has a temperature sensor which ensures optimal charging voltages at all temperatures.
Features
Maintains conditions and optimises battery life
Connect up to 2 DC energy sources; the D250S dual will select the optimum source.
Charging begins as soon as a DC source is connected
Can work with alternators or solar
Built Temperature Sensor for optimal charging
DIY – no need for heavy gauge wiring solar regulators or VSR
