The use of fans and climate control units in the switching cabinet means additional maintenance expenses and considerably higher costs. The ideal solution would be a drive design that does not allow any power loss in the switching cabinet. ACOPOSmulti gives the designer the free space required for conventional heat dissipation in the switching cabinet, a feed-through cooler with IP65 protection for releasing heat outside the switching cabinet and a cold plate variant for connecting to a cooling circulation system (water, oil).
