Vertiv GXT5-1500LVRT2UXLN 1500VA Online Double-Conversion Rack/Tower UPS
Overview
The Vertiv GXT5-1500LVRT2UXLN is a 1500VA/1350W online double-conversion UPS engineered for IT closets, network edge deployments, and security infrastructure where clean, uninterrupted power is non-negotiable. Unlike line-interactive designs that only engage during voltage events, the GXT5-1500LVRT2UXLN runs all connected equipment from a regulated inverter output 100% of the time — meaning your NVRs, switches, and access control panels never touch raw utility power. That zero-transfer-time topology matters most in environments where a 20ms switchover gap would drop a recording session or lock out a door controller.
The unit ships in a 2U rack form factor at 3.4 in H × 16.9 in W × 18.6 in D, but the flexible rack/tower chassis means it can also stand vertically in a server closet or IDF cabinet without additional hardware — a practical detail when you're retrofitting power protection into a space that wasn't originally planned for rack gear.
Key Features
- Online Double-Conversion Topology: The inverter is always in the power path, so there's no transfer time when utility power fails or fluctuates. For network video recorders writing continuously to disk, that means zero dropped frames at the moment of an outage — the load never sees the switchover.
- 1500VA / 1350W Capacity: The 0.9 power factor rating (1350W from 1500VA) reflects modern IT loads accurately. If you're sizing for a PoE switch drawing 200W plus an NVR at 80W plus a few access control panels, you have real headroom before the alarm threshold. Avoid loading above 80% continuously for battery runtime and thermal reasons.
- Up to 98% Efficiency in Active ECO Mode: In ECO mode, the unit bypasses the inverter during clean utility conditions and re-engages on deviation — delivering up to 98% efficiency and measurably lower heat output in a server room. On-line mode (always-inverting) reaches up to 95% efficiency. The tradeoff: ECO mode introduces a brief transfer event if utility quality degrades, so evaluate your load sensitivity before enabling it.
- Wide Input Voltage Range (60–150V): Accepts voltage swings from 60V to 150V before switching to battery — useful in older commercial buildings or warehouse environments where branch circuits run long cable runs and suffer measurable sag under load. The UPS absorbs those swings without discharging the battery unnecessarily.
- Six NEMA 5-15R Outlets with 4 Programmable Receptacles: Four of the six output outlets are individually programmable for load shedding, sequenced startup, or outlet-level scheduling. In a power and UPS deployment with mixed priority loads, you can assign your NVR and core switch to non-programmable (always-on) outlets while IP phones or non-critical devices sit on programmable outlets that can be shed first during a battery event.
- Configurable Output Voltage (110/115/120/125VAC ±3%): Output voltage is user-selectable in four steps, which matters when powering equipment with tight voltage tolerances or when pairing with isolation transformers downstream.
- Gravity-Sensing Color LCD Control Panel: The display automatically reorients when the chassis is switched between rack and tower orientation — no menu dive required after physical reconfiguration. Status, load percentage, battery runtime, and input/output voltage are all surfaced without connecting to a management interface.
- USB, RS232, RS485, and Terminal Block Interfaces: Out-of-the-box, the GXT5-1500LVRT2UXLN connects to a host system via USB for UPS monitoring through standard power management software. RS232 and RS485 ports support serial-based out-of-band management when network connectivity isn't available. The terminal block handles dry-contact signaling for integration with building management or third-party alerting systems.
- Optional IntelliSlot RDU120 for SNMP/Web Management: SNMP and web-based monitoring require the optional Vertiv Liebert IntelliSlot RDU120 communications card — it does not ship standard. If your deployment requires remote monitoring through a NMS or integration with a DCIM platform, budget for that card separately. Without it, network-layer UPS visibility is unavailable.
- ENERGY STAR 2.0 Certified, UL 1778, RoHS2, REACH: The ENERGY STAR 2.0 certification is relevant for facilities pursuing green building credits or subject to energy-efficiency procurement mandates. UL 1778 4th edition listing confirms the unit meets current safety standards for uninterruptible power systems in North American commercial installations. RoHS2 and REACH compliance cover hazardous substance restrictions for deployments subject to those regulations.
Integration & Compatibility
The GXT5-1500LVRT2UXLN integrates directly into standard 2U rack infrastructure and supports USB-based UPS monitoring compatible with most OS-level power management utilities. For network switch deployments where remote UPS visibility matters, the optional IntelliSlot RDU120 enables SNMP traps and web dashboard access — pair that with your NMS of choice for automated shutdown sequencing and event logging. The external battery connector port supports runtime extension via compatible external battery modules, though specific EBC compatibility should be confirmed against Vertiv's current accessory documentation. RS485 support enables integration into building automation and BMS environments common in larger commercial facilities. Review the UPS selection guide to match capacity and topology to your specific load profile before finalizing the deployment.
Frequently Asked Questions
Q: What is the difference between on-line mode and Active ECO mode on the GXT5-1500LVRT2UXLN?
A: In on-line mode, the inverter is always active and all connected equipment runs from regulated inverter output — zero transfer time on utility failure. Active ECO mode bypasses the inverter during clean utility conditions (reaching up to 98% efficiency) but introduces a brief transfer event if utility quality degrades. On-line mode tops out at 95% efficiency. Choose ECO mode for stable utility environments where efficiency is the priority; use on-line mode for sensitive loads that cannot tolerate any switchover event.
Q: Does the GXT5-1500LVRT2UXLN include SNMP and network management out of the box?
A: No. SNMP and web-based management require the optional Vertiv Liebert IntelliSlot RDU120 communications card, which is not included. The base unit ships with USB, RS232, RS485, and terminal block interfaces for local and serial management. If network-layer UPS monitoring is required, the RDU120 card must be ordered separately.
Q: Can the GXT5-1500LVRT2UXLN be used in both rack and tower orientations?
A: Yes. The chassis supports both rack-mount (2U, 16.9 in wide) and freestanding tower orientations. The color LCD panel features gravity-sensing orientation that automatically adjusts the display readout when the unit is repositioned — no reconfiguration required.
Q: What is the input voltage operating range of the GXT5-1500LVRT2UXLN?
A: The unit accepts input voltages from 60V to 150V (typical 120V) before switching to battery power. This wide range accommodates voltage sag and swell conditions common in older commercial buildings or facilities with long branch circuit runs.
Q: How many outlets does the GXT5-1500LVRT2UXLN provide, and are they all the same?
A: The unit provides six NEMA 5-15R output receptacles. Four of the six are individually programmable — supporting load shedding, sequenced startup, and outlet-level scheduling. The remaining two are non-programmable and remain on continuously during normal operation.
Q: What certifications does the GXT5-1500LVRT2UXLN carry?
A: The GXT5-1500LVRT2UXLN is ENERGY STAR 2.0 certified, UL 1778 4th edition listed, CSA 22.2 No. 107.1 listed, and compliant with RoHS2, REACH, and WEEE directives.
When I spec power protection for a security infrastructure deployment, the first question is always topology — and the GXT5-1500LVRT2UXLN answers it definitively with online double-conversion. Every watt delivered to your load passes through the inverter continuously, which means your NVRs, managed switches, and access control head-ends are isolated from every utility anomaly: sags, surges, frequency drift, and hard outages alike. That's the architecture you want when a 20ms gap in power would cause a door controller to reboot or an NVR to drop a recording session.
Technical Highlights:
- 98% Active ECO / 95% On-Line Efficiency: The 3-point efficiency gap between ECO and on-line mode is real and measurable in a 24/7 deployment. At 1350W continuous load, that delta translates to roughly 40W of additional heat dissipation in on-line mode — worth factoring into your cabinet thermal budget, especially in sealed IDF closets.
- 60–150V Input Range: That's an unusually wide acceptance band. In practice it means the unit won't hammer its battery during the voltage sag events (typically 90–100V) that are common on loaded branch circuits in older commercial buildings — the inverter compensates without battery discharge, preserving runtime for actual outages.
- 4 Programmable NEMA 5-15R Outlets: Outlet-level programmability lets you sequence startup (critical for NVRs that need the network online before they boot) and implement tiered load shedding during extended battery events — shed IP phones and workstations first, keep the NVR and core switch alive as long as possible.
Deployment Considerations:
- SNMP and web management are not included — the IntelliSlot RDU120 card is a separate purchase. If your deployment requires integration with a NMS or automated graceful shutdown scripting, confirm that card is in the BOM before installation day.
- The unit weighs 46.2 lb in a 2U chassis. In a fully loaded 2-post relay rack, verify your rack's weight rating before mounting — and plan for two-person installation. At 18.6 in depth, also confirm your rack has adequate clearance for cable management behind the unit.
The GXT5-1500LVRT2UXLN is the right call for a security headend closet running a mid-density NVR stack (8–16 channel), a PoE switch, and access control hardware — where zero-transfer-time protection and outlet-level programmability justify the online double-conversion premium over a line-interactive alternative.
