Product information

NOTE This device is a slave of the D250SA and does not operate independently.
120 A DC/DC energy management solution
Separates, prioritises and improves batteries and equipment
Smartpass 120 charges and supplies service batteries and equipment with 120 A, separates critical equipment from non-critical equipment and ensures that radio, emergency lighting and navigation systems are always powered.
Smart 120 is a 120 A energy management soldering that distributes, controls and maximises the available energy from the generator to power service batteries and extra batteries. The SMARTPASS 120 can handle all 12V batteries between 28 – 800 Ah. The Smartpass 120 battery protection function ensures that critical equipment such as radios, emergency lighting and navigation systems are always powered and prioritised when the extra battery voltage is low and disconnects non-critical consumers. The unit’s battery protection protects your service battery from total discharge and the built-in overheating protection reduces the charging current before the battery temperature becomes too high. SMART 120 is compatible with the D250SA 20A onboard charger.
