CTEK SmartPass 120S - 120A 40-289

CTEK Smartpass 120S is a 120A power management system designed to optimize the distribution and control of power from a vehicle's alternator to both starter and service batteries. Compatible with 12V batteries ranging from 28-800Ah, the Smartpass 120S prioritizes critical equipment by employing a Battery Guard function. This function ensures that radios, emergency lights, and navigation systems maintain power even during low service battery voltage by disconnecting non-essential consumers. The Smartpass 120S safeguards the service battery from complete discharge and incorporates over-temperature protection to regulate charging current before excessive battery heat develops. Additionally, this system is compatible with D250SA and D250SE 20A on-board chargers.
