CTEK Smartpass 120S

The CTEK Smartpass 120S is a 120A Power Management Solution designed to distribute, control, and maximize the available energy from your alternator to power service batteries and consumers. It ensures that critical equipment such as radios, emergency lights, and navigation systems always have power, even when the voltage on the service battery is low. The unit automatically disconnects non-critical consumers when needed to preserve power for essential equipment. The Smartpass 120S also includes a Battery Guard function to prevent total discharge of your service battery and features over-temperature protection to reduce charge current before battery temperature gets too high. It’s compatible with the D250SA and D250SE 20A onboard chargers, offering an advanced power management solution for a range of 12V applications, including marine, RV, and automotive systems.
