Ctek Smartpass 120s

The Smartpass 120S is an advanced energy management system specifically designed for starter batteries and secondary batteries. With a maximum output of 120 amps, it optimizes the energy distribution from the alternator to the service batteries and end devices. This system is suitable for all 12V batteries with a capacity of 28 to 800 Ah and features an intelligent battery monitoring function that ensures important devices like radios and navigation systems are prioritized for power supply. In case of low voltage, the system disconnects non-critical consumers to protect the service battery from deep discharge. Additionally, the Smartpass 120S includes integrated over-temperature protection that reduces the charging current before the battery temperature rises too high. With a temperature range of -20°C to +50°C, it is suitable for various operating conditions and provides reliable performance.

• Energy management for starter and secondary batteries
• Prioritization of important devices under low voltage
• Integrated over-temperature protection for safety
• Compatible with D250SA and D250SE chargers.
