UltraLITE Model ELC (600W - 2kW)
The UltraLITE Model ELC delivers reliable emergency backup power in a compact, front-access design with one of the smallest cabinet footprints in the industry—making it ideal for facilities where space is at a premium.
Providing a full 90 minutes of backup power, the ELC is compatible with all lighting applications and life safety systems, ensuring continuous operation of exit lamps, egress lighting, and other critical loads. Its regulated sine wave output not only guarantees uninterrupted illumination during outages but also extends the life of LED drivers, ballasts, and lamps, reducing long-term maintenance and replacement costs.
Built to meet the demands of today’s lighting technologies, the ELC offers a 1200% peak overload capacity, handling the high inrush currents of LED and HID fixtures with ease. Its True Online Double-Conversion topology provides clean, conditioned power, while automatic self-testing, data logging, and reporting simplify compliance and maintenance.
For added flexibility, the Timed Normally Off Bus “PLUS” option features an adjustable soft start to accommodate inrush from “normally off” emergency fixtures. Advanced DSP control, static and manual bypasses, and high-speed regulation ensure accuracy, reliability, and efficiency under all conditions.
Ideal for hospitals, schools, commercial buildings, industrial facilities, and public venues, the UltraLITE Model ELC is a space-saving solution that delivers maximum reliability, compatibility, and long-term performance for mission-critical emergency lighting systems.

FAQs
What are centralized lighting inverters and why use them?
A centralized lighting inverter is an electronic system that converts DC battery power to standard AC voltages to provide back-up for emergency lighting systems during a power outage. Centralized lighting inverters provide a single point source of power for all emergency lighting and exit signs. This provides for a controlled logical wiring scheme and results in a single point for monthly and annual testing.
Is the UltraLITE Model ELC capable of operating both normally off and normally on lighting fixtures?
Yes! Available on the Model ELC is a Normally On and optional Normally Off (standby) output bus. Both outputs may be configured with branch circuit breakers, allowing for an easy and less expensive installation.
Can all inverter systems handle the high inrush current associated with energizing normally off emergency fixtures?
No. Other manufacturers’ products may shut down if the high inrush current exceeds the inverter’s on-battery overload rating. This is not the case with the UltraLITE Model ELC! The ELC’s Timed Normally Off Bus “PLUS” option is provided with a user-programmable 0- to 3-second soft start control. This control limits the high inrush current and assures compatibility with various lighting types and manufacturers.
Is it important that lighting inverter systems provide a regulated output to emergency fixtures?
The answer is “yes” for many reasons. A regulated voltage source 1) provides stable voltage to sensitive light fixtures and LED drivers, 2) minimizes voltage drops associated with longer wire runs, and 3) results in less-frequent replacement of ballasts, lamps, and LED lighting fixtures in particular!
Does the UltraLITE Model ELC have a transfer time, and if so, is it important?
The Model ELC does not have a transfer time because of its online, double-conversion topology. Transfer time is the time it takes to recognize and deliver emergency power. The transfer time of any standby or “fast transfer” inverter results in a momentary interruption or break in output voltage. For many applications, this is simply not desirable. A 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.
Is the UltraLITE Model ELC NFPA 101 compliant?
Yes! The Model ELC is compatible with NFPA 101, 7.9.3.1.3 “Periodic Testing of Emergency Lighting Equipment.”
When supplying power to normally off emergency lights, are there any application issues to consider?
Yes. Adjustable transfer on delay and transfer off delay settings are often used. The transfer off delay in particular is often set at 10 to 15 minutes, allowing plenty of time for HID fixtures, if used in the area, to regain their full illumination. These adjustable time delays are standard when the UltraLITE Model ELC’s Timed Normally Off Bus “PLUS” is selected.
Is the UltraLITE Model ELC a fast transfer lighting inverter system?
No… It’s better! Fast transfer systems do experience a break in power. The Model ELC has an online, double conversion topology, which means that the inverter is always on. If there is a loss of power, the inverter will draw energy from the batteries instead of the normal AC input source, with no break in the power. Thus, the Model ELC exceeds the performance of all fast transfer systems.
Does the UltraLITE Model ELC preserve battery life?
Yes. The more a battery is discharged, the shorter the life. The Model ELC incorporates Variable Range Logic into its design. This is a feature that adjusts the switch to battery point based upon the percentage of load. Under lighter loads, the switch to battery point can be as low as -40% of the nominal voltage. Most other inverters will switch to battery at around -15% of the input voltage. So in the event of a brownout condition, the Model ELC will still maintain regulated power to the lights, without switching to battery backup. This results in the extended life of the batteries, which reduces the cost of maintenance.
