CTEK SMARTPASS 120S DCDC 12V Charger

CTEK SMARTPASS 120S DCDC 12V Charger

12V | Power management system for starter and service batteries
The Smartpass 120S is a 120A power management system that distributes, controls and optimizes the available energy of your alternator to power your utility battery and your consumers.The SMARTPASS 120S supports all 12V batteries from 28 to 800 Ah. The Smartpass 120S's Battery Guard feature ensures that critical equipment, such as radio, warning lights and navigation instruments, is always powered and has priority when the power battery voltage is low, by disconnecting non-critical easements.
Battery Guard will protect your easement battery from full discharge, and its built-in overheat protection device reduces the charging current before the temperature rises too high. SMARTPASS 120S is compatible with the D250SA and D250SE 20A on onboard chargers.
