Improved design for a cooler VFD Enclosure

How innovative VFD enclosure design is helping to manage heat. VFD enclosure heat  is typically managed through tried and tested means such as forced ventilation, moving heat sinks to the exterior (through back panel) or other means such as air conditioning. Each of these are viable solutions, though environmental and operational considerations may impact suitability.…

Thermal Management of Electrical Enclosures – a hot topic for reliability.

  On average 3 out of 10 enclosures require thermal cooling.  Why be concerned with thermal management of electrical enclosures? Based on statistics, 30% of operating systems are being heat stressed, resulting in poor performance, premature failure, and erratic operation. Nuisance drive tripping often comes to mind when thinking about enclosure heat, but the problem…
