• Battery separation eliminates diodes and VSr relays

• Charging of service batteries up to 100a, which reduces recharge 

time

• Separation of energy-consuming equipment and service batteries 

during charging increasing the expected life of 12V devices such as 

light bulbs, LEDs and other electronics and allows the battery to be 

charged from the alternator at a level that minimises recharge time 

[patent pending]

• temperature protection of services batteries reduces charge current at 

high temperatures [patent pending] 

• maximised battery life as a result of reduced incidences where the 

battery is undercharged 

• reduced charging times and costs by decreasing engine idling 

• reduced dependency on aC power onshore through efficient use of 

alternator and solar power

• reduced environmental impact through extended battery life and a 

reduced idle time 

• minimal installation time and cost

• Boats

• Campervans and rVs

• Caravans

• 4WDs

• Heavy vehicles

COMPATIBLE WITH
D250S DUaL

D250S DUaL and SmartPaSS

Combining the D250S DUaL and SmartPaSS ensures optimal battery 

charging.

the SmartPaSS manages the energy transfer through the D250S DUaL, 

which then converts and produces the optimal voltage of 14.4V, even if 

the alternator only produces 14V.

CtEK’s built-in Battery Watch technology allows the SmartPaSS to make 

full use of the majority of energy produced (up to 95 %) and distributes the 

power servicing battery banks, bow thrust batteries and electrical equip-

ment such as navigational systems. 

the SmartPaSS, properly manages and distributes power, directing en-

ergy to where it is needed most. this ensures that service batteries are pro-

tected from being deeply discharged, providing batteries with an optimal 

service life and reducing the frequency and need for regular traditional 

charging.

the SmartPaSS has a sensor which senses the battery temperature and 

reduces charge current at high battery temperatures.

SIMPLIFIED INSTALLATION 

the SmartPaSS eliminates the need for units with multiple outputs. all 

batteries can be charged and maintained through the unit.

the SmartPaSS converts a 110/230V charger with one output into a 

unit that serves both the service and starter battery. 

CtEK offers a 2 year guarantee on all DC/DC  chargers. CtEK customer 

support is an appreciated service, both with regard to general questions 

or  specific  issues  related  to  charging  and  CtEK  chargers.  Safety,  sim-

plicity and flexibility characterizes all products and solutions developed 

and  sold  by  CtEK.  CtEK  supply  chargers  to  more  than  60  countries 

throughout the world. CtEK is also a reliable OEm supplier to many of 

the world’s most prestigious car and motorcycle manufacturers.
