Thermal Edge Inc. | How VFD Heat Dissipation Affects Cooling in Electrical Enclosures

When installing a variable frequency drive (VFD) into an electrical enclosure, careful consideration needs to be given to the much higher heat losses of VFDs compared to other items of electrical equipment. This will have a direct impact on the total heat load of the electrical enclosure and the capacity and method of cooling to be adopted. Other factors to consider are the position of the VFD inside the enclosure as well as an assessment of the maximum allowed operating temperature of the VFD. Learn More
