Information
The Ctek D250SA is an intelligent DC-DC charger which maximises battery capacity as a charging solution where charging from mains power (AC) is not available. This makes it great for extended periods spent on the road or water. The 5 step process supplies 20 amps of charging power to any lead acid battery from 40a/h all the way up to 300ah. The charger has multiple-input technology, meaning you can simultaneously supply charge from your alternator (including smart alternators for newer, hi-tech vehicles), solar panels or even from wind power. Once the intelligent voltage sensitive charger recognises that your deep cycle leisure batteries are topped off, it will supply a maintenance charge output to the vehicle's starter battery to ensure you have full cranking power when its time to fire up the beast. The device is an all-in-one in terms of implying and completing your 12v, off grid setup. It removes the necessity for messy voltage sensitive relays used to split charging between batteries and even means you can throw your cheap solar panel regulator in the bin too, thanks to its MPPT (maximum power point tracking) technology. The Ctek D250SA is designed to endure tough conditions including operating temperatures ranging from negative 20 degrees Celsius all the way up to 50 degrees Celsius and with a 2 year warranty as standard you can trust that this 12V solution will go the distance in your 12v setup.
