Images are for illustration purposes only. E&OE Overview The D250S DUAL charger obtains its energy from DC sources such as alternators, solar panels or wind power and optimises this power to meet the charging requirements of different battery banks. 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. The D250S DUAL is particularly suitable for charging caravans, motor caravans, boats and second homes that do not have access to grid power supplies. 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. The D250S DUAL ensures that your batteries are always in good condition, quick charging and long battery lifetimes.The D250S DUAL is a fully automatic 5-stage charger that supplies 20A to 12V batteries of 40-300Ah. The charger is IP65 classified (water jet and dust protected and approved for outdoor use), protects vehicle electronics and is suitable for all types of lead-acid batteries (Wet, MF, Gel, AGM). It is supplied with a 2 year guarante Features Multi-step charging from alternators and solar panelsBattery separator that eliminates diodes and VSR relaysMaintenance charge of alternator batterySolar panel regulator with Maximum Power Point Tracking, synchronised with other current sources as alternatorSimplified installation and improve the performance of the charring of remote batteries for bow thrust of anchor winch by not need any heavy cables Specifications Volt : 12VCharging Voltage : 14.4V at 25°C, temperature compensatedCharging Current : 20ABack Current Drain : <1Ah/monthRipple : <4%Ambient Temperature : -20°C to +50°C, output power is reduced automatically at high temperaturesCharger Type : 5-step fully automatic chargingBattery Types : All types of 12V lead-acid batteries (WET, MF, Ca/Ca, AGM and GEL)Battery Capacity : 40–300AhDimensions : 192 x 110 x 65mm (L x W x H)Insulation Class : IP65Weight : 0.73kg Additional Information Protection IP65 Size 192mm x 110mm x 65mm Downloads Datasheet - CTEK D250S DUAL PDF File 540.72 KB Datasheet - CTEK D250S DUAL PDF File 3.33 MB
