Product Description

The IOTA IIS-550-I 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-550-I will supply 550W of power from the onboard battery supply. The IOTA IIS-550-I works in conjunction with fluorescent, incandescent, and LED lighting loads and will automatically run switched, normally-on, or normally-off designated emergency fixtures. The IIS-550-I is ideal for applications requiring an emergency source for lighting arrangements that utilize multiple lamp and fixture types. The IIS-550-I features a surface mount design and comes with a three-year warranty and seven-year pro-rata battery warranty.

  • IIS-550-I

  • IIS-550-I-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.
