OneMonroe's Integro Voltage Transformers are used in parallel circuits on airfields to step down the utility (line) voltage to run 6.6 Amp airfield lighting products. 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 directly buried.

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.

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.

Integro Series Isolation Transformers are approved to the FAA L-830 specification and are certified by ITS Testing Labs to FAA Advisory Circular 150/5345-47. All Integro Transformers undergo 100% Quality Testing which includes visual inspection, ratio testing, heat testing and HIPOT testing after heating and 12 hour soaking.

Integro Series Isolation Transformers are wound for 6.6 and 20 Amp primary circuit applications. They are encapsulated in thermoplastic rubber for superior durability and dielectric strength and are manufactured with 2 primary and 1 secondary FAA L-823 listed leads.

We proudly manufacture all of our products in the USA, all of our Airfield Lighting Power equipment meets the Buy American Preference requirements in 49 USC 50101 and is certified to be used on AIP-funded projects requiring Buy American Preferences.
