Vertiv GXT5LI-1000LVRT2UXLN 1000VA Lithium-Ion Online Rack UPS with Network Card
The Vertiv GXT5LI-1000LVRT2UXLN is a 1000VA / 1000W double-conversion online UPS in a 2U rackmount form factor, built around a lithium-ion battery chemistry and shipped with an included IntelliSlot RDU120 network management card. It's the right pick when you need true online (zero-transfer-time) power conditioning for a small server room, network closet, IP surveillance head-end, or edge computing stack — and you want SNMP/web management without buying an add-on card separately. For engineers comparing it against conventional VRLA models: the Li-Ion chemistry is the defining spec here, and its implications run through runtime, weight, service life, and temperature behavior.
Overview
Double-conversion (online) topology means utility power is continuously rectified and re-inverted — the protected load never draws directly from the AC line. Every voltage fluctuation, frequency deviation, and switching transient is isolated before it reaches your equipment. The GXT5LI-1000LVRT2UXLN delivers 1000W of clean 120V output regardless of what the upstream feed is doing, as long as input stays within the 60–150 VAC max window. That's a wider catch range than most entry-level UPS units, which matters in older buildings, generator-backed panels, and international deployments running 100V or 110V nominal. Output voltage is user-configurable among 100 / 110 / 115 / 120 / 125VAC to match your equipment's nominal requirement.
Key Features
- Lithium-Ion Battery Chemistry: Li-Ion cells run lighter and longer than sealed lead-acid. The unit ships at 37.5 lbs — meaningful when you're populating a high-density rack or working solo on an install. Li-Ion also tolerates higher ambient temperatures better than VRLA and typically delivers longer calendar life, which reduces the frequency of battery replacement cycles in unmanned edge sites.
- True Online Double-Conversion: Zero transfer time to battery — the load is always running through the inverter. This matters for sensitive network and recording equipment that can fault on even a 4ms transfer gap. If you've seen NVRs or switches hiccup on line-interactive UPS transfers, this topology eliminates that failure mode.
- 98% Efficiency in Active ECO Mode: In ECO mode, efficiency climbs to 98%, which meaningfully reduces heat load and operating cost in 24/7 deployments. Online mode delivers up to 92%. For a 1000W unit running around the clock, the difference between 92% and 98% efficiency represents real wattage lost as heat — relevant in thermally constrained enclosures.
- Wide Input Voltage Window (60–150 VAC max): The unit accepts input down to 60V before switching to battery. Combined with a nominal operating range of 102–150 VAC at full load, this UPS stays on utility power through browndowns that would force a narrower-window unit onto battery, preserving battery cycle life.
- Included IntelliSlot RDU120 Network Card: SNMP and web-based management ship in the box — no separate card purchase required. That means out-of-the-box remote monitoring, alerting, and graceful shutdown integration with your NMS or VMS management layer. The unit also exposes USB, RS-232, and dry-contact terminal block interfaces for environments where network management isn't available or desired.
- Six NEMA 5-15R Output Receptacles: Six standard outlets cover a typical edge stack — switch, NVR, workstation, and a few ancillary devices — without needing a PDU in front of the UPS. Input connects via NEMA 5-15P, so it drops into any standard 15A wall or PDU circuit.
- User-Configurable Output Voltage: Selectable among 100 / 110 / 115 / 120 / 125VAC output lets you match the UPS to the load's nominal voltage, useful when protecting equipment rated for international voltage ranges or when running a mixed-voltage lab environment.
- Color Graphic LCD with Gravity-Sensing Orientation: The front panel display rotates its readout based on whether the unit is racked horizontally or standing vertically. In practice this means the same unit installs in a rack or on a shelf and the display is always right-side-up without manual configuration.
- Energy Star 2.0 and UL Listings (UL 1778, UL 1973, UL 1642): UL 1778 is the UPS safety standard; UL 1973 covers the lithium battery system. Energy Star 2.0 qualification matters for government procurement and for facilities tracking power consumption against sustainability targets. RoHS, WEEE, and REACH compliance covers disposal and export requirements for EU and regulated environments.
Integration and Compatibility
The included network UPS management card (IntelliSlot RDU120) supports SNMP and web protocols, making it compatible with most enterprise NMS platforms and VMS systems that support UPS status monitoring. The dry-contact terminal block and RS-232 port provide legacy integration paths for building automation systems or older SCADA environments. The Intellislot bay also accepts other Vertiv management cards if you need to swap to a different protocol or add environmental monitoring — check the Vertiv UPS line for compatible Intellislot options.
For NVR and video surveillance head-end installations, this unit pairs well with a PoE switch and recording server drawing under 1000W combined. If your load budget is tighter, model the actual draw — 1000W is the capacity ceiling, not a comfortable sustained operating point. Leave 20–30% headroom for inrush and future expansion. For larger surveillance closets or multi-server stacks, consider a higher-capacity unit in the same GXT5 family. A UPS sizing and runtime guide can help you work through load calculations before committing to this capacity tier.
Frequently Asked Questions
Q: What is the difference between online double-conversion and line-interactive topology on the GXT5LI-1000LVRT2UXLN?
A: The GXT5LI-1000LVRT2UXLN uses true online double-conversion, meaning the load always runs through the inverter. There is zero transfer time to battery during a power failure. Line-interactive UPS units have a 2–10ms transfer gap that can cause sensitive equipment to fault. For NVRs, servers, and managed switches, online topology is the more reliable choice.
Q: Does the GXT5LI-1000LVRT2UXLN include a network management card?
A: Yes. The unit ships with a Vertiv Liebert IntelliSlot RDU120 network card installed, which supports SNMP and web-based management. No additional card purchase is required for remote monitoring and graceful shutdown integration.
Q: What input voltage range does the GXT5LI-1000LVRT2UXLN support?
A: At full load, the nominal operating range is 102–150 VAC. The maximum accepted input range is 60–150 VAC. Below 60V, the unit transfers to battery. This wide window helps preserve battery cycle life during brownout conditions.
Q: Can the GXT5LI-1000LVRT2UXLN be mounted in a standard rack?
A: Yes. It is a 2U rackmount unit measuring 3.4 in (H) × 16.9 in (W) × 17.3 in (D) and weighs 37.5 lbs. The color LCD display includes gravity-sensing orientation, so the readout is correct whether the unit is rack-mounted or used in a tower/shelf orientation.
Q: What certifications does the GXT5LI-1000LVRT2UXLN carry?
A: The unit is listed to UL 1778 (UPS safety), UL 1973 (battery safety), and UL 1642. It also carries Energy Star 2.0, RoHS, WEEE, and REACH compliance. These listings cover safety, energy efficiency, and environmental/export regulatory requirements.
Q: What output receptacles are on the GXT5LI-1000LVRT2UXLN?
A: The unit provides six NEMA 5-15R output receptacles. Input is via a NEMA 5-15P plug for connection to a standard 15A circuit.
The spec that defines this unit for me is the combination of Li-Ion chemistry and the included RDU120 card on the GXT5LI-1000LVRT2UXLN. Most 1000VA online UPS units at this price tier ship with VRLA batteries and no management card — you're paying extra for both upgrades here, but they're not optional on a properly managed surveillance or edge network site.
Technical Highlights:
- 98% Active ECO Mode Efficiency: Running 24/7 at 92% vs. 98% efficiency on a 1000W unit adds up — ECO mode cuts resistive losses significantly and reduces heat output in the enclosure. If the protected load is stable and not highly transient, ECO mode is worth enabling.
- 60–150 VAC Max Input Window: This is a wider catch range than typical. On generator-backed circuits during transfer, input voltage can sag below 100V briefly. The 60V floor means the unit stays on utility (or generator) power through those transients instead of hammering the battery.
- UL 1973 Battery Listing: Li-Ion UPS units require separate battery safety certification. UL 1973 is the standard — confirm your AHJ accepts it before deploying in jurisdictions with strict equipment approval requirements, particularly in data centers or life-safety-adjacent spaces.
Deployment Considerations:
- The IntelliSlot bay accepts other Vertiv management cards, so if your site already standardizes on a different protocol card, the included RDU120 can be swapped — but verify card compatibility against the GXT5 family before purchasing alternates.
- Operating temperature ceiling is 104°F (40°C) with a 10% derating at 50°C. In a sealed comms cabinet in a warm warehouse or outdoor enclosure, measure ambient before assuming this unit will run at full rated output.
This unit is well-positioned for a network closet or surveillance head-end running an NVR, PoE switch, and management workstation under 800W combined — where you need true online topology, want SNMP visibility from day one, and prefer Li-Ion to reduce the service cadence on battery replacements.
