High power flat wound construction, low cost!
Unique oval-shaped ceramic core construction offers a low
profile body for minimal height installation. Available in a wide
range of power ratings from 40W to 450W. Feature all-welded
construction and integral mounting brackets, allows stackable
mounting configurations for increased power ratings. Series
FWE (edgewound) offers highest size-to-power ratio making it
ideally suited for load testing, power distribution, high power
instrumentation, etc.
