Energy management device that controls and optimises the energy produced by the generators, solar modules, wind turbines or conventional chargers. It is distributed to the battery bank or to consumers that require energy, such as deep-cycle battery bank, bow thruster batteries, consumers etc. Together with the D250S DUAL, SmartPass offers an optimal charging with the unique, multi-layered CTEK-charging cycle that not only charges but also protects your batteries. In addition, it has an integrated battery monitor that protects the deep-cycle batteries from harmful complete discharging and ensures that important equipment, such as radio, emergency lighting and navigation systems, always work. It has a temperature sensor that protects the batteries against high temperatures.
The combination of D250S DUAL and SmartPass guarantees optimum battery charging. The SmartPass manages the energy transfer via the D250S DUAL, which converts and provides the optimum voltage of 14.4 V, even if the generator only produces 14 V.
