  • Single Phase, On-Line Double Conversion Emergency Lighting Inverter System (ELIS) The Staco 924 full range of centralized lighting inverters extend from 10.8kW to 18kW and provide full power protection for all emergency lighting applications. The Voltage and Frequency Independent (VFI) design provides exceptional voltage regulation and ensures lumens, drivers and ballasts on the Staco 924-protected circuit are fully operable when most needed - for egress lighting. With the highest level of power protection, a full range of power capacities to fit installation needs, and one of the best warranties in the industry, the Staco 924 is the ideal solution for all emergency lighting requirements.
  • Three Phase, On-Line Double Conversion, Central Lighting Inverter In the event of an AC power failure, the Staco E3 924 will automatically transfer to battery power and continue to provide power without any interruption for the full amount of time you select. When power returns, the Staco E3 924 will automatically recharge the batteries for the next unexpected power outage or disturbance.
  • Three Phase, On-Line Double Conversion, UL924 Central Lighting Inverter In the event of an AC power failure, FirstLine® PL 924 automatically supports the connected lighting loads on battery power and will continue to provide power without any interruption for a full 90 minutes. When the utility power returns to normal, FirstLine® P 924 will automatically recharge the batteries to be ready for the next power disturbance. In addition to meeting life safety requirements, the FirstLine®P 924 can also increase the life expectancy of the protected lighting system and reduce long-term cost of ownership.
  • Three Phase, On-Line Double Conversion, UL924 Central Lighting Inverter In the event of an AC power failure, FirstLine®PLT 924 automatically supports the connected lighting loads on battery power and will continue to provide power without any interruption for a full 90 minutes. When the utility power returns to normal, FirstLine®PLT 924 will automatically recharge the batteries to be ready for the next power disturbance.
