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.
