UltraLITE Model ELU Emergency Lighting Inverters UL924

UltraLITE Model ELU Emergency Lighting Inverters UL924UltraLITE Model ELU Emergency Lighting Inverters UL 924, 1.5kW to 14kW, by Controlled Power, meet the NFPA 101 and NFPA 111 standards and are considered “Life Safety Equipment” and are UL 924 listed as “Emergency Lighting Equipment”.  The UltraLITE Model ELU provides the required 90 minutes of emergency backup power, and is 100% compatible with all lighting applications and life safety systems. The voltage regulation and performance characteristics of the Model ELU extend ballast, LED driver, and lamp life, which make this product an advantageous choice over competing lighting inverters. Whether fed from the AC power source or even while in battery mode, the ELU has a peak overload capability up to 1400% to accommodate inrush current from LED fixtures.

Now Seismic-Rated, the ELU has been shake-table tested and meets seismic standards which satisfy applicable portions of the California Building Code (CBC 2016) and the International Building Code (IBC 2015). The verification testing required is recognized and accepted throughout the U.S.
