Product Description

The IOTA IIS-375-LED is a UL Listed stand-alone sine wave output inverter designed to provide power to designated emergency lighting fixtures. In a power loss situation, the IOTA IIS-375-LED will supply 375W of power from the onboard battery supply. The IOTA IIS-375-LED is designed specifically for LED applications and capable of handling in-rush currents of LED drivers without de-rating load size from the full rated output. The IIS-375-LED will automatically run switched, normally-on, or normally-off designated emergency fixtures. The IIS-375-LED is ideal for applications requiring an emergency source for lighting arrangements that utilize multiple LED fixture types. The IIS-375-LED features a surface mount design and comes with a three-year warranty and seven-year pro-rata battery warranty.

  • IIS-375-LED-DR (Dimming Relay Option)
    Dimming Relay leads allow for a dimming signal to operate the luminaires in the desired, dimmed state during normal operation and then bypass the dimming control to operate the fixtures at full light output in the emergency mode. Additionally, if desired, the dimming leads can be wired to operate the luminaires at a reduced lumen output setting during emergency operation based on the dimmable driver(s) being used. Refer to the installation manual for details.
