  • Mayport 400Hz SS Converter
  • 400 Hz Mayport installed at Mayport Naval Air Station, Florida

Benefits & Features

The “Mayport” is designed for outdoor use in extreme harsh weather. It’s Harsh Weather Enclosure was originally designed for its name sake, the Mayport Naval Air Station in Jacksonville Florida. The equipment at NAS Mayport is exposed to high levels of solar radiation, extreme rain and wind storms, salt laden air, tropical storms and hurricanes, all of these conditions amplified by Helicopters taking off and landing just a few feet away.


The Mayport’s enclosure is actually two compartments with slightly different features: One side (with the electronics) is a NEMA 4. The other side (with the transformers and heat sinks) is a NEMA 3R.


Anticorrosion features are incorporated throughout so the Mayport will remain free of rust and corrosion, and will provide dependable service when you need it most, when the weather is really bad. When you’re ground power equipment is permanently installed outdoors, and operations are conducted during harsh weather, the Mayport is the model you need.
