CTEK Smartpass 120 charges and supplies the service battery and equipment with 120A, separates critical equipment from non-critical equipment ensuring that radio, emergency lights and navigation systems always have power. It’s a 120A Power Management Solution which distributes, controls and maximises the available energy from your alternator to power service batteries and consumers. SMARTPASS 120 handles all 12V batteries between 28-800Ah.

Its Battery Guard function ensures that critical equipment always has power and takes priority when the voltage on the service battery is low, disconnecting non-critical consumers.

CTEK SMARTPASS 120 is compatible with the D250SA 20A on board charger.
