Smartpass 120S charges and supplies the battery and service equipment with 120A, separates critical equipment from non-critical to ensuring radio, emergency lights and navigation systems always have power. Smartpass 120S is a 120A power management solution that distributes, controls and maximizes the available power of your alternator to power batteries and service consumers. SMARTPASS 120S handles all 12V batteries between 28-800Ah. The Smartpass 120Ss Battery Guard feature ensures critical equipment such as radio, emergency lights and navigation systems always have power and take priority when the voltage in the service battery is low, disconnecting non-critical consumers. The battery protector of the unit will protect your service battery from total discharge and the built-in overtemperature protection reduces the charging current before the battery temperature is too high. SMARTPASS 120S is compatible with D250SA and D250SE 20A on-board chargers.
