Elite MIIS-550-I 550W Interruptible

550W Emergency Lighting Inverter by Elite

The MIIS-550-I from Elite is a stand-alone sine wave inverter designed to power emergency lighting from its onboard battery during a power loss. It is suitable for surface-mount installations. Key features include 550W output, 120V to 277V input, and compatibility with LED, fluorescent, and incandescent fixtures.

Key Features and Benefits of This Emergency Inverter

One unit can supply designated emergency fixtures, instead of fitting a battery pack into each one. It automatically runs switched, normally-on, or normally-off emergency fixtures. Working with LED, fluorescent, and incandescent loads gives flexibility when a building uses mixed lighting types.

Where to Use the MIIS-550-I Emergency Inverter

This inverter suits buildings that need backup lighting for designated emergency fixtures, such as exit routes in commercial or institutional spaces. The listed operating temperature is 20 to 30 degrees Celsius, which points to conditioned indoor areas, not unheated or outdoor locations.

Installation and Compatibility Checks

Before purchasing, add up the load of your emergency fixtures and keep it within 550 watts. Confirm that your supply is 120V to 277V and that the surface-mount housing has room at the intended location. Emergency lighting requirements vary, so check them with your local authority.

Additional Buying Context

The unit is UL Listed and carries a three-year warranty with a seven-year pro-rata battery warranty. Dimensions and a location rating are not listed on the page, so consult the specification sheet to plan the installation space.
