CTEK Smartpass120 DC/DC 120A Power Management System



Fully automatic self-contained 120A power management system Simple DIY installation - Rapid DC/DC fast charging Up to 350A boost for 10 seconds!
The Smartpass 120 is a fully automatic 120A power management system that distributes power between the starter battery, the service battery and on-board equipment, without the need for traditional diodes or voltage sensitive relays.
With Dynamic Over Current Protection, the Smartpass 120 can provide outputs of up to 350A for up to 10 seconds, essential for powering equipment like winches that need more than 120A.
Additionally, by using Current Source Priority it supplies power to critical equipment directly from the alternator when the engine is running. This means critical functions like starter batteries, radios, emergency lights and communication systems always have the power they need, and take priority over non-critical functions.
Along with Start Assistance uses power from your service battery to help get your engine started if your starter battery is flat and Battery Temperature Protection will switch off charging if your service battery temperature is too high.
The Smartpass 120 truly is the smart way to manage your vehicles power systems, ensuring your batteries will be charged and youll have power when you need it.
