SMARTPASS 120
SMARTPASS 120 is a fully automatic 120A power
management system that prioritizes, controls and
maximizes energy from your alternator to power your
service battery. It safely separates your starter and
service batteries automatically. It also distributes power
between the starter battery, the service battery and on
board equipment without the need for traditional diodes
or VSR relays. This means that SMARTPASS 120 can
make sure that critical functions like starters, radios,
emergency lights and communication systems always
have the power they need, and take priority over non-
critical functions.
SMARTPASS 120 works with any 12V lead acid battery.
It can also be used with the CTEK D250SA 20A on board
charger for the ultimate 140A power management
system.
