TrueLITE Model ELS
TrueLITE Model ELS
(58.5kW to 112.5kW) Three Phase
Emergency Lighting Inverters UL924
Description:
The TrueLITE Model ELS is an LED-compatible three phase emergency lighting inverter featuring an intelligent, robust design that provides enhanced levels of quality, reliability, and energy savings!
This unique inverter offers four (4) field-selectable modes of operation based on input power conditions, lighting design, and the desire for high operating efficiency.
On-Line: Under all input power conditions, the inverter output supplies the load with power that is isolated, as well as voltage and frequency regulated.
Standby-On (ECO-Mode): When the bypass input source is within voltage and frequency limits, it powers the load and provides an operating efficiency up to 98.5%.
Smart Active: Automatically defines whether to operate in Standby-On (ECO-Mode) or On-Line mode, based on the quality / stability of the incoming power source. Smart Active mode allows for an operating efficiency of up to 98.5%, as long as the incoming power source is within preset limits and is stable.
Standby-Off: The output of the inverter is normally off, and exclusively feeds emergency lighting that is only meant to be energized in the event of a power outage.
Whether fed from the AC power source or even while in battery mode, the Model ELS has a peak overload capability of 1200% to accommodate inrush current from LED fixtures!
With advanced diagnostics, monitoring, remote communication options, and automatic testing and data-logging, the Model ELS is NFPA 101 compliant. This inverter is UL 924 Listed as “Emergency Lighting and Power Equipment” and “Auxiliary Lighting and Power Equipment”; as well as C-UL Listed to CSA C22.2 No. 141-15 as “Emergency Lighting Equipment”.
Optional Seismic-Rated Models Available!
The Model ELS has been shake-table tested, and is offered with an optional seismic rating. These models meet seismic standards which satisfy applicable portions of the ICC – AC156 “Acceptance Criteria for Seismic Certification by Shake-Table Testing of Nonstructural Components and Systems”, ASCE 7 – 10, and International Building Code (IBC 2015). The verification testing required is recognized and accepted throughout the U.S. and many other countries.
Features & Benefits
- LED Inrush Compatible – Peak overload capability of 1200% to accommodate the inrush current from LED fixtures / drivers while the inverter is fed from the AC power source, or even while in battery mode
- Full Compliance with NFPA 101 – computer-based, self-testing / self-diagnostic emergency lighting system with data-logging
- Reliable Operation – Incorporates galvanic isolation and a robust design with a high overload capacity to deliver reliable emergency power for critical life safety loads
- Battery Care System – Deep discharge protection, current limitation, and voltage compensation based on ambient temperature all combine to prolong battery life and reduce usage by using different recharging methods
- Input Source – DSP-controlled, IGBT-based rectifier circuitry provides a high input power factor of 0.99, low input current distortion of ≤3%, and a “power walk-in” function that limits input current surge seen by the power source
- High Efficiency – Operates in ECO-mode to provide an efficiency rating of up to 98.5%, without compromising critical features, diagnostics, and monitoring
- Four (4) cabinet configurations available (1 – 4 battery cabinets); kW rating and runtime dependent
- Digital monitor with a wide graphic LCD display provides a close-up, detailed overview of the inverter status in real-time
- Monitor displays all electrical parameters and alarm logs; and allows access to user-programmable settings
- Automatic battery testing; results logged with time and date stamp, and a pass or fail indication. Failed battery tests result in an audible and visual alarm
- Standard 90 minutes of battery backup
- Optional runtimes of 30, 60, and 120 minutes are available
- Optional wall-mounted, 3-breaker maintenance bypass is available in 14K, 35K, or 65K AIC ratings for 480/277V applications
- Up to 12 optional status / alarm relay contacts available, in addition to the 3 standard contacts provided
- Optional network communications via Ethernet TCP/IP, BACnet/IP, or MODBUS TCP/IP provide remote monitoring of the inverter status, battery tests, alarm conditions, and electrical measurements
- Optional serial communications allow for monitoring using MODBUS/JBUS protocols on RS485 or PROFIBUS
