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 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 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 a 2-year warranty.

FASTER CHARGING

The D250SE automatically delivers the optimum charge so your 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 the need for a regulator. It also features a Maximum Power
PointTracker (MPPT) to get the maximum power out of your solar panels.

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 are shut 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.

Linked with the smart pass 120 giving you up to 140amps output

Smartpass120s Product information

120ADC/DC Power Management Solution

Separate, prioritise and boost batteries and equipment

Smart pass120S charges and supplies the service battery and equipment with120A, separates critical equipment from non-critical equipment ensuring that radio, emergency lights and navigation systems always have power.

Smartpass120 is a 120A Power Management Solution which distributes, controls and maximises the available energy from your alternator to power service batteries and consumers. SMARTPASS 120S handles all 12V batteries between 28-800Ah. The Smartpass 120’s Battery Guard function ensures that critical equipment such as radio, emergency lights and navigation systems always have power and take priority when the voltage on the service battery is low disconnecting non-critical consumers. The unit’s Battery Guard will protect your service battery from total discharge and built in over temperature protection reduces charge current before the battery temperature gets too high. SMARTPASS 120S is compatible with the D250SE orD250SA 20A on board charger.
