The EON meets NFPA 101, NFPA 111, NEC and IBC requirements, and provides the industry’s most advanced life safety system testing available!
Key EON options include output distribution with either monitored or unmonitored circuit breakers, normally off bus for standby (normally off) emergency light fixtures, and remote communications via BACnet, Ethernet, MODBUS TCP, or MODBUS RS485.
The EON features one of the smallest three phase cabinet footprints in the industry! See how our 90 minute Inverter cabinet footprint compares to others!
Available in 10kW to 33kW three phase sizes, the EON is the ideal emergency power solution for facilities where safe egress and life safety are imperative.
Three Phase Sizes: 10kW, 13kW, 14kW, 15kW, 16kW, 17kW, 20kW, 22kW, 24kW, 26kW, 28kW, 30kW, 32kW, and 33kW

A centralized lighting inverter is an electronic system that converts DC battery power to standard AC voltages to provide back-up for 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.
YES! The EON is UL 924 listed under Emergency Lighting and Power Equipment, in accordance with the ANSI/NFPA 101 “Life Safety Code”, Article 700 of ANSI/NFPA 70, “National Electric Code”, and the “International Building Code” (IBC).
YES! The EON meets the NFPA 101 definition of a computer-based, self-testing / self-diagnostic emergency lighting system with data-logging (NFPA 220.127.116.11.3). Both periodic and annual tests are performed automatically, and the results are logged with a date and time stamp. Both alarm and test logs provide a history of events, and the ability to generate an NFPA-compliant report.
BIG difference! The EON’s “Egress Lighting Integrity Test” provides the industry’s most advanced life safety system test available. To satisfy NFPA-mandated periodic and annual requirements, the EON’s Intellistat TS monitor automatically initiates the testing of all life safety circuits, regardless of egress lighting design (“always on” or “normally off”). The Intellistat TS then compares power consumption during the test period with user-defined load capacity, analyzes the data, and advises if service is required.
YES! During these NFPA-mandated tests, an optional “test activated” contact may be used to activate one or more remotely installed ZoneSaver-2 emergency lighting control units. When activated, the ZoneSaver-2 will feed emergency power to egress lighting that is normally off, or dimmed / turned off via a local control device. This option allows for automatic testing of the locally controlled life safety circuit and the ZoneSaver-2 control unit. Consult factory for product and application details.
YES! The EON’s 90 minute configuration requires only one (1) battery cabinet, and only batteries with front access terminals are used. This makes installation easy and less time consuming – installation is straightforward and DC connections are easily made!
YES! Option one is isolated, potential free (Form C) Status / Alarm Relay Contacts, accessible via a terminal strip for a hardwired connection to building monitoring and security systems. Option two is network communications. The EON’s NetMinder™ option communicates system status, test results, alarms, and electrical measurements via BACnet/IP or BACnet MS/TP, Ethernet TCP/IP, MODBUS TCP, or MODBUS RS485.
YES! Provided in a side-mounted 14” wide, front access distribution cabinet, a total of 12 pole positions per phase (36 total) are available to accommodate 1, 2, and 3 pole circuit breakers fed from an inverter system output of 208/120 VAC or 248/277 VAC. These circuit breakers are located behind a secured, lockable, hinged door; and can be factory-wired to the normally on bus and/or normally off bus in any combination specified.
YES! Monitored output circuit breakers are available, reducing the number of pole positions to 8 per phase (24 total). If a circuit breaker is open, the Intellistat TS™ monitor sounds an alarm. Optional alarm relay contacts are also available.
YES! The EON has a normally on output bus and an optional normally off output bus. Both outputs may be configured with branch circuit breakers, allowing for an easy and less expensive installation.
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, which allows plenty of time for HID fixtures (if used in the area) to regain their full illumination. These adjustable time delays are standard when the EON’s normally off bus is selected.
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 EON Model EL3! The EON’s normally off bus option includes 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.
The answer is YES for many reasons. Here are some of them. A regulated voltage source: 1) Provides stable voltage to sensitive light fixtures, e.g. HID and LED fixtures. 2) Minimizes voltage drops associated with longer wire runs. 3) Results in less-frequent replacement of ballasts, LED drivers, and lamps in particular! 4) Facility egress lumens are maintained 100% (will not diminish) over the full 90 minutes of emergency power.
The answer is NO…its better! Fast transfer systems do experience a break in power. The EON 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 EON exceeds the performance of all fast transfer systems.
The answer is NO. Fast-transfer inverter systems feed the AC input power source directly to the LED fixtures. The quality of the power feeding the LED fixtures depends on the quality of the AC power source. If voltage sags, surges and transients are present…the LED fixtures will be affected, often causing premature failure.
The EON 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 insures that there is no interruption of power to the lighting fixtures. This is a very important factor with HID and high pressure sodium lighting. Lighting control systems and alarm circuits may also need a no break type system because of the circuit power requirements.
YES! The EON is a true no-break lighting inverter system, 100% compatible with HID and HPS fixtures. Stand-by inverters produce up to a 1/2 cycle of power interruption, causing HID lighting to extinguish. Once this occurs, it will typically take the lamp 10 minutes or so to regain full illumination.
