Smartpass 120S is a 120A power management solution that distributes and controls power from the alternator to batteries and service consumers. It prioritises critical equipment and disconnects non-critical consumers when the service battery voltage drops.
Smartpass 120S is a 120A power management solution that distributes, controls, and maximizes the available power from your alternator to power batteries and service consumers. It handles all 12V batteries between 28-800Ah. The Smartpass 120Ss Battery Guard feature ensures critical equipment like radio, emergency lights, and navigation systems always have power and take priority when the voltage in the service battery drops low. It also disconnects non-critical consumers. The battery protector prevents the service battery from total discharge, and the built-in overtemperature protection reduces the charging current before the battery temperature rises too high. Smartpass 120S is compatible with D250SA and D250SE 20A on-board chargers.
