Mechanically, the product consists of two units, the Power Unit and the Control Unit. The power unit can contain one to six modules (cooling plates), depending on the drive size. Instead of air, Vacon NX Liq- uid-Cooled inverters and frequency converters use liquid for cooling. A charging circuit is embodied in the frequency converters but not in inverters.
