(550W to 1.5kW)

Emergency Lighting Inverters UL924


Meeting the NFPA 101 and NFPA 111 standards, the eLITE Model ELN is considered “Life Safety Equipment.” The Model ELN is also UL 924 listed as “Emergency Lighting Equipment,” providing the required 90 minutes of emergency backup power. With a front-access design and a small footprint, the Model ELN is suited for wall- or floor-mounted installations.

The Model ELN is compatible with LED drivers/fixtures, and is a perfect choice when providing emergency power to fan motor loads that are a part of the life safety system.

  • What is a lighting inverter?
    • A lighting inverter is an electronic system that converts DC battery power to standard AC voltages to provide back-up for emergency lighting systems. This inverter provides convenient emergency power for all types of lighting fixtures, increasing its usability.
  • Why use centralized lighting inverters?
    • Centralized lighting inverters provide a single point source of power for all emergency lighting and exit signs. This allows for a convenient point of maintenance and provides for a controlled, logical wiring scheme. The output of the inverter is fed to a dedicated lighting panel, which provides power exclusively for the emergency lighting system.
  • Is there a difference in lighting inverters?
    • Yes! Lighting inverters differ in switch time, voltage regulation, and power conditioning. The standards for emergency lighting inverters are defined in the UL 924 test procedures. These procedures omit the difference in characteristics. Some inverters may take up to 1 to 2 seconds to respond to a power outage, while others provide a seamless transfer. The seamless transfer systems provide the kind of power necessary for sensitive electronic lighting, HID fixtures, lighting controls, and alarm circuits.
  • How important is the transfer time?
    • Transfer time is the time it takes to recognize and deliver emergency power. An inverter providing zero transfer time ensures that there is no interruption of power to the emergency lighting fixtures. Lighting control systems and alarm circuits may also need a no-break type system because of the circuit power requirements.
  • Should lighting inverters include voltage regulation and power conditioning?
    • Yes. Voltage regulation ensures that voltage drops and brownouts do not affect the overall lighting system. Voltage regulation also ensures proper lighting levels during normal operating conditions in “Normally On” circuits. Power conditioning prevents voltage surges and transients from reaching the electronic ballasts and/or LED drivers, thus providing longer life of the lighting fixture.
  • Can any UPS (battery backup) be used for emergency lighting?
    • No. Emergency lighting systems are governed by UL 924 standards. Only lighting inverters that have been tested and certified to this standard can be used.

Controlled Power Company warrants the eLITE Model ELN Emergency Lighting Inverter to be free from defects in material and workmanship for a period of two (2) years following shipment from the factory. Batteries are warranted with a one (1) year full replacement, and 14 year pro-rated warranty. Controlled Power Company agrees to replace, F.O.B. its factory, any parts which fault through defect in material or workmanship during the warranty period.

Warranty begins from date of shipment unless a factory start-up is purchased, then the warranty begins from date of start-up or 90 days from ship date; whichever comes first.

Consult the factory for additional warranty details, and a description of start-up services provided.
