Product Details

With award winning Swedish technology, the dual input D250SE which has now replaced the D250SA  with added connection to lithium batteries 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 suppliesup to 20A of power to charge, condition and maintain any 12V lead acid service battery from 40-300Ah, including Wet,MF, Gel, AGM. EFB and Ca/Ca & lifepo4 Lithium.

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) and comes with a2-year warranty.

This system is supplied with pre terminated leads to save you time and money on expensive crimping tools

Features

FASTERCHARGING

TheD250SE automatically delivers the optimum charge soyour batteries are fully charged in the shortest possible time.You

can select normal or 14.7V AGM charge voltages. It also has a temperature sensor to compensate for hot or cold conditions and

avoid the risk of your battery overheating or overcharging.

DIRECT CONNECTION FOR SOLAR POWER

TheD250SE has an input for connecting solar panels without theneed for a regulator. It also features a Maximum Power

PointTracker (MPPT) to get the maximum power out of your solarpanels.

SMART ALTERNATOR COMPATIBILITY

Vehicle manufacturers are now introducing smart ECU (Engine ControlUnit) controlled alternators to increase fuel efficiency

and lower emissions. Smart alternators deliver a variable out-put and areshut off when they’re not needed.

TheD250SE will still operate even if the smart alternator is shutoff and maintain a stable output of up to 20A to fully

charge your battery in the shortest time.

FEATURES

• 5step charging from smart and conventional alternators andDC sources, such as solar and wind

• Automatic battery separator works without the need for diodes orVSR relays

• SelectableAGM mode for AGM batteries

• Parallel input from both alternator and solar panel

• Solarpanel regulator with Maximum Power Point Tracking (MPPT)

• Starter battery maintenance charging when your service battery isfully charged
