Advantages of IEM’s ATS:

Fully rated bus is based on density ratings, not UL heat rise tests, resulting in more bus and lower operating temperatures.

All enclosures are designed for specific application with improved dimensional flexibility and finished using state-of-the-art powder coating system, providing an indoor finish that exceeds the 1500-hour salt spray testing requirement for outdoor equipment to 3000 hours.
