MACS’ Integrated Functions

AC MODBOX® added value

D Compact solution with low height and reduced roof print.

D Highest protection for harsh environmental conditions (dust, rain, snow, ice, hails, sand, wind, salty atmosphere, UV radiation).

D Reduced transmitted noise (airborne and structural) for increased passenger comfort.

D Optimized aerodynamic drag and reduced energy losses and consumption at high speed.

D Integration of other high voltage functions (voltage and current sensors, surge arrester, roof line disconnector).

D Reduced engineering, logistics, assembly and test efforts for car builders.

D Reduced risks for engineering and installation.
