CTEK Smartpass DC to DC Power Management System 120A 40-289

The CTEK SmartPass120S is a power management system that charges and supplies service battery equipment with 120A and separates the essential equipment from non-essential equipment during operation to ensure that radio, emergency lights and nav systems are prioritised for power at times when voltage is low.

In addition, its safety features protect your service battery from total discharge and from potential damage incurred from temperature increases, reducing charge current before battery temperature gets too high, by way of its in-built temperature sensor. Compatible with D250SA and D250SE 20A on-board chargers.
