Powerful on-board, on the move charging
Our DC-DC on-board charging system quickly charges your service battery and distributes power safely and reliably. If you don’t have access to mains power, this is the set-up for you, that takes power from the vehicle alternator and other alternative power sources, whilst on the move. There are two different units both of which can work independently or together as part of a powerful system.
The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V service battery. It has selectable charge voltages for AGM and Lithium* batteries and takes power through its dual input from alternator, solar panel and wind power.
Smartpass 120S is a power management solution which distributes, controls and maximises up to 120A of power from the vehicle alternator and can also ensure that the charging of critical equipment takes priority.
Both units can maintain a stable output to vehicles fitted with Smart ECU controlled alternators.
Combine these two products together for a powerful and smart 140A charging and power management system.
