Download CTEK MXT 14 User Manual Charge while you driveBattery to Smart battery charger in a dual battery applicationThe 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 is a fully automatic 5-stage charger that supplies 20A to 12V batteries of 40–300Ah. It 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. The D250S DUAL automatically selects the best connected DC energy source (of 2) for the purpose and switches between them to achieve high efficiency multi-stage charging. It is suitable for all types of lead-acid batteries (Wet, MF, Gel, AGM). The charger is IP65 classified (water jet and dust protected and approved for outdoor use) and protects vehicle electronics. The charger comes with a 2-year warranty.Max charge current 20A.Charges batteries 40Ah to 300Ah.Automatic starter/service battery separation.Adapts to parallel energy sources. For use with alternator, solar or both.Built-in solar regulator and temperature sensor.Input voltage 12.9–22V DC; 14.4V Charge voltage.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 cablesSplash and dust proof (IP65)Maximised battery life due to minimised undercharge timeMaximised battery capacity when the battery is kept fully charged avoiding harmful sulphate crystals on the lead plates and stratification of the battery acid.Ability to take charge automatically from any power source that is connected to the D250S DUALReduced charging times and costs by decreasing engine idling and the dependency on AC power onshore through efficient use of alternator and solar powerReduced environmental impact through extended battery life and a reduced idle timeMinimal installation time and cost easy to replace an isolating relay or diode separatorInput 23V maxOutput 14.4V, 20A maxBack current drain* Corresponding to less than 1Ah/monthAmbient temperature -20˚C to 50˚CBattery types All types of lead-acid batteries, 12V, WET, MF, Ca/Ca, AGM, GELBattery capacity 40-300AhWarranty 2 yearsMPPT YesInsulation class IP652-year warrantyCTEK guarantee to the buyer by the name indicated on the receipt of APRTECH only guarantee can not be transferred to others.
