Integro FAA Approved Series Isolation Transformers are used to isolate high operating voltage for constant current airfield lights in a series circuit. They are encapsulated and designed to operate efficiently while submerged in water. They are approved to operate between -55 C and + 65 C and can be installed above ground, in metal cans or direct buried.
Where They are Used
Integro Series Isolation Transformers are installed at most major airports in the United States and Mexico, as well as in many countries in South America, Europe, Asia and Africa. Our American made Series Isolation Transformers are also preferred at many military airports in the United States.
