CTEK – Smartpass 120S 120A Power Management System

Smartpass 120S not only charges and supplies the battery and service equipment with 120A power, but it also separates critical equipment from non-critical to ensure that the 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 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.
