Vertiv GXT5LI-1500LVRT2UXL Online Double-Conversion Lithium-Ion UPS, 1500VA / 1350W, 2U Rack/Tower
Overview
The Vertiv GXT5LI-1500LVRT2UXL is a 1500VA / 1350W online double-conversion UPS in a 2U rack/tower form factor, purpose-built for lithium-ion battery modules. Where traditional lead-acid UPS units add bulk and long recharge times to your equipment room, this platform accepts Vertiv lithium-ion battery modules that recharge faster, operate across a wider temperature window, and occupy less space — critical factors in dense edge deployments and security-critical equipment rooms. Note that lithium-ion battery modules are sold separately; this unit ships without batteries installed.
For security integrators and IT architects deploying rack-mount UPS systems in surveillance, access control, or network closet applications, the GXT5LI-1500LVRT2UXL delivers continuous online protection — every connected load runs off the inverter continuously, with the utility feeding a rectifier. There is no transfer time on utility failure because the inverter never switches off. That matters for NVRs, managed PoE switches, and access control panels where even a 10ms switchover can reset equipment.
Key Features
- Online Double-Conversion Topology: All connected loads run off the inverter at all times — zero transfer time on utility failure. For NVRs or PoE switches feeding door controllers, this eliminates the brief interruption that causes equipment resets during a switchover-based UPS transition.
- 1500VA / 1350W Power Rating: At a 0.9 power factor, the rated watts match the VA — relevant when loading servers or switching power supplies that draw close to unity PF. Size a load list to 80% of 1350W (1080W) for thermal and runtime headroom.
- 98% Efficiency in Active ECO Mode: Standard online mode runs at up to 92% efficiency. Active ECO Mode reaches 98%, reducing heat dissipation and operating costs in 24/7 environments. ECO mode bypasses the inverter under clean utility conditions and engages full double-conversion automatically on anomalies — a practical setting for stable grid environments.
- Wide Input Voltage Range — 60–150 VAC Max, 102–150 VAC at Full Load: The wide input window (down to 60 VAC absolute max, 102 VAC nominal at full load) lets the unit ride through browndowns that would force a lesser UPS onto battery. Fewer battery cycles means longer battery service life and less runtime depletion during minor grid fluctuations.
- User-Configurable Output Voltage (100/110/115/120/125 VAC): Output can be set to five voltage levels, which gives you flexibility when deploying equipment with narrower input tolerance or when retargeting the unit for a different facility.
- Six NEMA 5-15R Output Receptacles: Six individually accessible outlets serve a typical mix of NVR, PoE switch, access control panel, and workstation loads — without requiring a PDU. Input is NEMA 5-15P for direct wall or PDU connection.
- Lithium-Ion Battery Architecture: Li-ion chemistry charges significantly faster than VRLA lead-acid (typically 3–4x), tolerates higher ambient temperatures without proportional degradation, and offers a longer service life measured in charge cycles. This extends the interval between battery replacements in warm equipment rooms or compact enclosures. Batteries are required and sold separately — confirm module compatibility before ordering.
- Color Graphic LCD with Gravity-Sensing Orientation: The display auto-rotates for rack or tower installation, so you get a readable readout regardless of form factor orientation. Gravity sensing means no manual display reconfiguration when transitioning between deployments.
- Multiple Management Interfaces — USB, RS-232, Dry-Contact, IntelliSlot: Out-of-band management via USB or serial is available without add-ons. The IntelliSlot bay accepts the optional Vertiv Liebert IntelliSlot RDU120 network card for SNMP and web-based monitoring — essential for remote UPS health monitoring in unmanned equipment rooms. Dry-contact terminal block provides hardware-level signaling to building automation or alarm systems.
- Energy Star 2.0 / UL 1778 / UL 1973 / UL 1642 Listed: UL 1778 covers the UPS system, UL 1973 and UL 1642 cover the battery subsystem — relevant for insurance, code compliance, and data center certifications. Energy Star 2.0 designation supports facility sustainability targets and potential utility rebate programs.
- Operating Temperature 32°F to 104°F (0°C to 40°C): Rated to 40°C continuous with a 10% derating noted at 50°C. Most equipment rooms run 18–25°C, so the thermal envelope is not limiting in standard deployments. For warmer edge closets, verify ambient stays below 40°C or plan for derating.
Integration & Compatibility
The GXT5LI-1500LVRT2UXL integrates into standard 19-inch rack enclosures at 2U and fits equally in tower orientation on a shelf. The rack enclosure must accommodate a depth of 18.7 inches (plus cable management). At 39.7 lbs without batteries, plan for a mid-rail shelf or full side-rail mounting — front-rail only is not appropriate for this weight class.
SNMP and web management require the separately purchased Vertiv Liebert IntelliSlot RDU120 network card installed in the IntelliSlot bay. Without it, management is limited to USB and RS-232 local interfaces. For deployments that require remote UPS monitoring through a network management platform, budget for the management card at the outset rather than retrofitting later.
The dry-contact terminal block supports integration with building management systems and third-party alarm panels — useful in physical security deployments where UPS status should feed into an access control or monitoring platform alongside door and camera events. Pair this unit with a PDU or automatic transfer switch upstream if your installation requires dual-feed redundancy.
The GXT5LI-1500LVRT2UXL is part of the broader Vertiv Liebert power protection line, which includes compatible lithium-ion battery cabinets and external battery modules for extended runtime. Confirm battery module part numbers directly with Vertiv documentation — the base unit ships without batteries.
Frequently Asked Questions
Q: Does the GXT5LI-1500LVRT2UXL include lithium-ion batteries?
A: No. The GXT5LI-1500LVRT2UXL is designed to use Vertiv lithium-ion battery modules, but batteries are required separately and are not included with this unit. Confirm compatible battery module part numbers with Vertiv documentation before ordering.
Q: What is the transfer time to battery on power failure?
A: Because the GXT5LI-1500LVRT2UXL uses an online double-conversion topology, connected loads run off the inverter continuously. There is no transfer time — the inverter does not switch on utility failure because it never switches off. This makes it suitable for sensitive equipment that cannot tolerate even brief power interruptions.
Q: Does the GXT5LI-1500LVRT2UXL support SNMP network management?
A: SNMP and web-based management require the optional Vertiv Liebert IntelliSlot RDU120 network card, which is sold separately and installs in the IntelliSlot bay. Without this card, the unit supports USB and RS-232 serial management interfaces only.
Q: Can this UPS be mounted in both rack and tower orientations?
A: Yes. The GXT5LI-1500LVRT2UXL supports both 2U rack and tower installation. The color LCD display includes gravity-sensing orientation so the readout automatically adjusts for whichever mounting position is used.
Q: What certifications does the GXT5LI-1500LVRT2UXL carry?
A: The unit is listed under UL 1778 (UPS systems), UL 1973 (battery systems for stationary applications), and UL 1642 (lithium batteries). It also meets Energy Star 2.0 and carries RoHS, WEEE, and REACH compliance markings.
Q: What is the maximum operating temperature?
A: The unit is rated for continuous operation from 32°F to 104°F (0°C to 40°C). Vertiv notes a 10% derating at 50°C — meaning output capacity should be reduced if ambient temperatures approach that level.
The GXT5LI-1500LVRT2UXL is the unit I reach for when a client needs genuine zero-transfer-time protection for a mixed NVR and PoE switch rack — specifically because the online double-conversion topology means there is no switchover event whatsoever. Every watt flowing to your connected loads is inverter-sourced, full stop. The 1350W real-power rating at a 0.9 power factor is honest; you don't lose capacity to a low PF penalty the way you might with older UPS designs rated in VA only.
Technical Highlights:
- 98% Active ECO Efficiency: In a 24/7 surveillance or access control room, running at 98% versus 92% online efficiency is measurable in annual operating costs — less heat generated means less cooling load and lower electricity spend over a multi-year deployment lifecycle.
- Wide Input Range (60–150 VAC Absolute Max): The 60 VAC absolute floor means this unit rides through severe brownouts that would push a narrower-window UPS onto battery repeatedly — each unnecessary battery cycle is life off your Li-ion modules, so this range matters for sites with unreliable utility power.
- IntelliSlot Management Architecture: The slot-based card approach means you can deploy now without the network card and add SNMP/web monitoring later without hardware replacement — clean upgrade path for phased rollouts where remote management gets funded in a later budget cycle.
Deployment Considerations:
- Budget for lithium-ion battery modules at the outset — the GXT5LI-1500LVRT2UXL ships without batteries. The total landed cost of the system includes the battery modules, and Li-ion modules carry a price premium over VRLA that should be factored into the project budget versus the longer replacement interval.
- At 18.7 inches deep and 39.7 lbs (without batteries), this unit requires full side-rail mounting in the rack — do not front-rail mount. Verify your rack's depth and rail capacity, and add battery module weight to the loaded weight calculation before finalizing rack position.
The GXT5LI-1500LVRT2UXL is the right call for a security operations center or unmanned edge equipment room where runtime extensibility via Li-ion battery modules matters more than upfront cost — particularly when you need SNMP visibility into UPS health through the IntelliSlot RDU120 card as part of a broader network monitoring strategy.
