CTEK SMARTPASS 120S with installation kit

Power management system for starter batteries and auxiliary batteries

Separates, prioritizes, and supports batteries and end devices.

The Smartpass 120S charges and supplies the service battery and end devices with 120A, separates critical from non-critical devices, and ensures that the radio, emergency lights, and navigation systems are always powered. The Smartpass 120S is a 120A power management system that distributes, controls, and maximizes the energy supplied by the alternator to power the service batteries and end devices. The Smartpass 120S is suitable for all 12V batteries between 28Ah and 800Ah. The Smartpass 120S battery monitor function prioritizes essential devices such as the radio, emergency lights, and navigation systems by providing them with priority power, while non-critical consumers are switched off when the service battery voltage is low. The device's battery monitor protects your service battery from deep discharge, and the integrated over-temperature protection reduces the charging current before the battery temperature rises too high. SMARTPASS 120S is compatible with the D250SA and D250SE on-board chargers.
