CTEK Specialist Battery Chargers

CTEK D250SE- 20A DC/DC Battery Charger With award winning Swedish technology, the dual input D250SE can draw its power from smart alternators and other DC sources, making it the ideal charger for vehicles that don’t have access to a mains power supply. Its dual input capability means it can draw power from solar and wind sources, in parallel to the alternator. The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to charge, condition and maintain any 12V lead acid service battery from 40-300Ah, including Wet, MF, Gel, AGM. EFB, Ca/ Ca and LFP. The D250SE uses patented technology so it’s safe for you and your vehicle’s electronics. It’s also IP65 classified (splash and dust proof, and suitable for outdoor use)

Features:

• Solar panel regulator with MPPT technology • Starter battery maintenance charging when your service battery is fully charged

• 5 step charging • Automatic battery separator eliminates diodes and VSRs • Selectable mode for AGM & LFP batteries

CTEK Smartpass 120S - 120A On Board Power Management System SMARTPASS 120S is a fully automatic 120A power management system that prioritises, controls and maximises energy from your alternator to power your service battery. It safely separates your starter and service batteries automatically. It also distributes power between the starter battery, the service battery and on board equipment without the need for traditional diodes or VSR relays. This means that SMARTPASS 120S can make sure that critical functions like starters, radios, emergency lights and communication systems always have the power they need, and take priority over non-critical functions. SMARTPASS 120S works with any 12V lead acid battery. It can also be used with the CTEK D250SE 20A on board charger for the ultimate 140A power management system.

Features: • Automatic battery separation eliminates diodes and VSRs • Fast charging of auxiliary batteries

• Separation of loads and batteries during charging, increasing life of 12V devices • Battery temperature protection
