Integrated Functional Units A key of Microelettrica Scientifica success is the ability to provide specific solutions to meet customers’ requirements. One of these are IFUs: different Microelettrica Scientifica contactors and disconnectors are supplied already assembled on a structure. Several solutions have been supplied also including charging and discharging resistors on the same frame. In this way customers do not have to worry about installing several components on a vehicle: it’s just a matter of inserting the whole assembly in its own cubicle and tightening some screws. For example, all...
