PASS 120
120A ON BOARD POWER MANAGEMENT SYSTEM
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 noncritical 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.
FEATURES
• Automatic battery separator works
without the need for diodes or VSR relays
• Battery Guard makes sure that critical
functions always have power and
protects your service battery from total
discharge
• Start Assistance uses power from your
service battery to help get your engine
started if your starter battery is flat
• Dynamic Over Current Protection to
handle outputs of up to 350A for up to
10 seconds
• Battery temperature protection switches
o charging if your service battery
temperature is too high
• Current Source priority supplies power
to critical equipment directly from the
alternator when the engine is running
• Starter battery maintenance charging
when your service battery is fully charged

COMBINE YOUR ON BOARD SYSTEMS
SMARTPASS 120 and D250SA can be used independently but
work best together when combined for service batteries larger
than 100Ah.

FLAT STARTER BATTERY? NO PROBLEM
SMARTPASS 120 has a Start Assistance function that uses
current from your service battery to start your engine when
your starter battery is flat so you’re back on the road quickly.
NEED MORE POWER? NO PROBLEM
If you’re using equipment like winches that need more than
120A, SMARTPASS 120’s Dynamic Overcurrent Protection
function can give you outputs of up to 350A for short bursts
up to 10 seconds.
THE ULTIMATE POWER MANAGEMENT SOLUTION
Combine your SMARTPASS 120 with the D250SA for a system
that delivers up to 140A to your service batteries while you’re
on the move. The combined system can draw its power from
the alternator – including smart alternators – as well as solar
and wind generated power. The system is optimized for AGM
batteries and can deliver a fully automatic 5 step charge to
charge, condition and maintain any 12V lead acid battery from
28-800Ah.
