Campervan and Motorhome Electrical

Features: microprocessor controlled split charge system - automatic 3 stage charging (constant current, constant voltage and float mode) - charge status LED indicators - short curcuit protection - automatic cut in and drop out - isolates different voltage systems - output controlled to maximum current - will fully charge starter battery/batteries before switching to fast charge the auxiliary battery bank - can be left permanently connected - neat and compact design - dimensions = 170mm wide x 125 deep x 155 high. Will fast charge auxiliary battery at 20 amps until leisure/auxiliary battery is at full charge. Whereas conventional split charge systems/relays will cut back once the battery has a surface charge (i.e. the battery voltage has come back up, but the battery is not actually fully charged)the battery to battery charger will keep charging until the auxiliary battery/batteries are completely fully charged.

Very simple to fit. Connect to the batteries only - no connection to the alternator is required.

Supplied with 4 metres of cable.

Available in 4 different voltage options --- 12 volt starter battery to 12 volt leisure/auxiliary (20 amp output) --- 12 volt starter to 24 volt leisure/auxiliary (10 amp output) --- 24 volt starter to 24 volt leisure/auxiliary (10 amp output) --- 24 volt starter to 12 volt leisure/auxiliary (20 amp output).

The D250S 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 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.
The D250S has a temperature sensor which ensures optimal charging voltages at all temperatures. The D250S ensures that your batteries are always in good condition, quick charging and long battery lifetimes.
The D250S is a fully automatic 5-stage charger that supplies 20A to 12V batteries of 40-500Ah. 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 guarantee.
Very simple to fit. Connect to the batteries only - no connection to the alternator is required.

Dimensions = 197 x 93 x 49mm (L x W x H)

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 guarantee.
