NDS POWER SERVICE - All-In-One Triple Charger

NDS GOLD 40A DC-DC Charger

The NDS Power Service Gold 40-M is an all-in-one triple charger for your leisure battery.  This compact unit can manage multiple charging sources thanks to its combination of a 40A battery-to-battery (DC-DC) charger, a 20A mains-powered charger and a 250W PWM solar controller, enabling you to charge from your vehicle’s alternator whilst on the move, from an AC mains hook-up whilst on site, or from solar panels whilst off-grid. This saves space, cabling and installation time when compared with fitting three separate pieces of equipment.

The Power Service Gold-40M optimises the charging of your 12 volt battery from multiple sources and can be fitted to vehicles with either standard or Euro 6 ‘smart’ alternators. It can be used with all lead-acid batteries and lithium batteries and has dedicated, selectable charging profiles for each type.

Important – only to be used with solar panels that have an Open-Circuit Voltage (V_OC) of 28V or less.  Greater voltages may damage the unit and will void the warranty.

Suitable for 12V nominal voltage systems.
