CTEK Smartpass 120S on Board Power Management

Your starter battery, service batteries and on-board equipment are your lifeline when you’re heading on a remote off-road adventure and the new SMARTPASS 120 is a fully automatic, 120A on-board power management system that gives you full control over that power.

The SMARTPASS 120 safely distributes power between the starter and service batteries as well as on-board devices, without the need for traditional diodes or VSR relays, and it’s just one of a number of smart features.

Power management system for starter and service batteries

Smartpass 120S 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 120Ss 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 D250SA and D250SE 20A on board chargers.
