Vertiv GXT5-1500LVRT2UXLTAA 1500VA Online Double-Conversion Rack UPS
Overview
The Vertiv GXT5-1500LVRT2UXLTAA is a 1500VA / 1350W online double-conversion UPS in a 2U rack/tower form factor, designed for edge deployments, small server rooms, and security infrastructure racks where continuous clean power is non-negotiable. Unlike line-interactive designs that only correct voltage during disturbances, the GXT5 regenerates output power continuously — your connected equipment never sees raw utility power. For surveillance NVRs, network switches, or access control servers that cannot tolerate even a half-cycle transfer gap, that distinction matters operationally.
The GXT5-1500LVRT2UXLTAA (often searched as GXT5 1500LVRT2UXLTAA) accepts a wide input range of 60–150V on a standard NEMA 5-15P plug, handling the voltage sag and swell conditions common in commercial buildings without switching to battery unnecessarily — extending battery life over years of operation.
Key Features
- Online Double-Conversion Topology: Output power is synthesized from a regulated inverter at all times, not switched in on fault. For NVRs writing continuous video streams or access control panels managing door states, this eliminates the transfer-time exposure that line-interactive units carry — a practical distinction in 24/7 security infrastructure.
- 1500VA / 1350W Capacity: At 0.9 power factor, 1350W of real power supports a dense 2U rack load — typically four to six mid-range PoE switches, a small NVR, and an access control server simultaneously. Size your load to 70–80% of capacity (roughly 945–1080W) to maintain battery runtime and avoid thermal throttling.
- Wide Input Range (60–150V): The 60–150V acceptance window means the unit stays on utility power through voltage sags that would force a narrower UPS onto battery. In facilities with aging electrical infrastructure or generators as backup feeds, this range directly reduces unnecessary battery cycling.
- Up to 98% Efficiency in Active ECO Mode: In ECO mode, the inverter steps aside when utility power is clean and stable, achieving up to 98% efficiency — reducing heat output and operating costs in always-on rack environments. Online mode still delivers up to 95% efficiency for environments that require full double-conversion at all times.
- User-Configurable Output Voltage (110/115/120/125VAC ±3%): Output voltage is selectable across four settings, which matters when integrating equipment with narrow input tolerances or when matching the output to a specific load's rated voltage. The ±3% regulation ensures consistent delivery even as the inverter compensates for input variations.
- 6× NEMA 5-15R Output Receptacles: Six outlets on a single 2U unit means you can consolidate power for a complete edge rack — NVR, switch, router, and access control head-end — without a separate PDU. Each outlet draws from the same protected, conditioned feed.
- 2U Rack/Tower Convertible Form Factor: At 3.4 in H × 16.9 in W × 18.6 in D, the GXT5 fits a standard 2U rack slot without consuming the 3U that some competing 1500VA units require. Tower orientation is also supported for wiring closets or non-rack deployments.
- NEMA 5-15P Input Plug: Standard 15A plug means no dedicated circuit or hardwiring — install into any standard commercial outlet. Verify your circuit can sustain the load; on a 15A breaker, budget no more than 12A continuous (80% rule) which aligns with the GXT5's rated load.
Integration and Compatibility
The GXT5-1500LVRT2UXLTAA fits naturally into Vertiv power infrastructure deployments alongside rack PDUs, environmental monitoring, and remote management cards (verify card compatibility with the GXT5 chassis before ordering). For security integrators speccing a complete UPS and power protection stack, the 2U footprint leaves room in a standard 12U or 16U security rack for NVRs, PoE switches, and patch panels.
The wide input voltage range makes this unit compatible with generator-backed circuits common in commercial security deployments, where generator voltage output can vary at startup. For environments planning PoE switch deployments, factor the switch's PoE budget into your load calculation — a fully loaded 24-port 802.3af switch can draw 200W or more before adding camera loads, which stacks quickly against the 1350W ceiling. Consult a UPS sizing guide before finalizing load assignments.
Frequently Asked Questions
Q: What is the difference between the GXT5-1500LVRT2UXLTAA's ECO mode and online mode?
A: In ECO mode, the unit passes utility power through with minimal processing when the input is stable, achieving up to 98% efficiency. In online mode, the inverter synthesizes output continuously from a regulated DC bus, providing full double-conversion protection at up to 95% efficiency. ECO mode saves energy in stable utility environments; online mode is the right choice when power quality is poor or when connected equipment is intolerant of any input variation.
Q: How many devices can the GXT5-1500LVRT2UXLTAA power simultaneously?
A: The unit provides six NEMA 5-15R outlets and 1350W of real power. Practical load for sustained runtime is 70–80% of capacity, or roughly 945–1080W. A typical security rack (NVR, 24-port PoE switch, access control server, and network router) often falls in the 400–700W range, leaving headroom. Always sum actual device wattages under operating load before commissioning.
Q: Can the GXT5-1500LVRT2UXLTAA be used in tower orientation, or is it rack-only?
A: The GXT5-1500LVRT2UXLTAA supports both rack and tower mounting. At 3.4 in H × 16.9 in W × 18.6 in D it occupies 2U in a rack, and can also be oriented vertically as a tower unit for wiring closets or non-rack environments.
Q: What is the input plug type on the GXT5-1500LVRT2UXLTAA?
A: The unit uses a NEMA 5-15P input plug, which connects to a standard 15A commercial outlet. No dedicated circuit or hardwired connection is required. On a 15A circuit, keep continuous draw at or below 12A (80% of breaker rating) to avoid nuisance trips — factor this into your load planning.
Q: What input voltage range does the GXT5-1500LVRT2UXLTAA accept before switching to battery?
A: The unit accepts input from 60V to 150V (nominal 120V) while remaining on utility power. This wide range accommodates voltage sags, brownouts, and generator output variation without unnecessarily discharging the battery — important in facilities with aging electrical infrastructure or frequent generator switchover events.
Q: Can I configure the output voltage on the GXT5-1500LVRT2UXLTAA?
A: Yes. Output voltage is user-selectable at 110, 115, 120, or 125VAC, regulated to ±3%. This is useful when connected equipment has specific rated voltage requirements or when you want to ensure compatibility with loads designed for slightly different nominal voltages.
The GXT5-1500LVRT2UXLTAA is one of the cleaner options in the 1500VA class for security rack deployments specifically because it hits 98% efficiency in ECO mode — that is not a spec you typically see at this price tier, and it translates directly to lower heat output in a sealed IDF closet where every watt of waste heat matters for equipment longevity.
Technical Highlights:
- Online Double-Conversion: No transfer time on fault — the inverter is always carrying the load. For NVRs mid-write or access control panels managing door-hold states, this is the architecture you want, not line-interactive with its 4–8ms transfer window.
- 60–150V Input Window: Covers generator startup droop and end-of-feed brownout conditions that would push a standard 88–110V or 95–130V unit onto battery repeatedly. Fewer battery cycles over the unit's service life means longer battery health between replacements.
- 0.9 Power Factor at 1350W: The 1500VA / 1350W spec reflects a 0.9 PF rating — closer to unity than older 0.8 PF designs. At real security rack loads (mostly switched-mode PSUs presenting near-unity PF), you get closer to the nameplate watts than you would from a legacy UPS with the same VA rating.
Deployment Considerations:
- At 46.2 lbs, this is a two-person rack install — particularly relevant in overhead-shelf or mid-rack positions. Plan the lift before you schedule the installation window.
- The NEMA 5-15P input limits you to 15A circuits. If your rack load approaches or exceeds 1080W sustained (80% of 1350W), you are close enough to the circuit breaker limit that a single additional device could cause a nuisance trip. Budget load headroom or consider a 20A circuit with an appropriate input cord before deployment.
For a wiring closet or edge security rack in a commercial building — four to six IP cameras via a PoE switch, a small NVR, and an access control server — the GXT5-1500LVRT2UXLTAA fits the load profile cleanly and the 2U footprint keeps the rack organized. It is not the right pick for a high-density server room where you need parallel redundancy or three-phase input, but for single-phase edge security infrastructure it handles the job without oversizing the budget.
