Vertiv GXT5-750LVRT2UXL 750VA/750W Online Double Conversion UPS
The Vertiv Liebert GXT5-750LVRT2UXL delivers true online double-conversion protection for mission-critical network infrastructure, security recording systems, and edge-of-network deployments requiring clean, conditioned power. Rated at 750VA/750W with unity power factor capability, this 2U rack/tower convertible UPS protects against voltage sags, surges, spikes, and complete power failures while maintaining zero transfer time and pure sine wave output. ENERGY STAR 2.0 certification and up to 98% efficiency in Active ECO mode reduce operating costs without compromising protection, making it ideal for continuous-duty applications where both reliability and energy efficiency matter.

The GXT5-750LVRT2UXL's online double-conversion architecture processes 100% of incoming utility power through the rectifier, battery, and inverter stages continuously, isolating connected equipment from all line disturbances including harmonics, frequency variations, and voltage fluctuations. Unlike line-interactive or standby topologies that switch to battery during anomalies, double-conversion UPS systems provide zero transfer time — the inverter is always powering the load, so there's no relay click, no momentary dropout, and no risk of nuisance reboots when utility voltage dips. This makes the GXT5 series particularly well-suited for IP security NVRs, PoE-powered camera systems, access control panels, network switches, and any application where even a 4-millisecond transfer time is unacceptable.
Power factor matters more than ever. Modern switch-mode power supplies in servers, NVRs, and network gear operate at power factors approaching 1.0, meaning they draw watts nearly equal to their VA rating. Legacy UPS systems rated 750VA at 0.7 power factor deliver only 525W of usable capacity, forcing you to oversize by 40% or risk overload alarms. The GXT5-750LVRT2UXL supports power factors from 0.9 to 1.0, delivering the full 750W from its 750VA rating — you buy exactly the capacity you need, not 30-40% extra to compensate for an outdated power factor assumption. The LCD display shows real-time load percentage and power factor, so you can verify headroom at a glance during commissioning or when adding equipment.
Battery management is purpose-built for 24/7 installations. The hot-swappable internal battery slides out the front of the chassis without tools, so a technician can replace an aging battery during a maintenance window without scheduling downtime or removing the UPS from the rack. The GXT5 continuously monitors battery health, tracks charge cycles, and estimates remaining runtime based on current load, displaying the prediction on the LCD and reporting it via SNMP if the optional network card is installed. When you connect an external battery cabinet (sold separately), the UPS auto-detects the additional capacity within seconds and recalculates runtime — no DIP switches, no software configuration, no guesswork. A single GXT5-750LVRT2UXL can support multiple external cabinets, extending runtime from the standard 5-8 minutes at full load to 30 minutes or more for orderly shutdown of multi-drive NVRs or to ride through brief utility maintenance windows.
Programmable outlet groups let you implement load shedding, startup sequencing, or remote troubleshooting strategies that would otherwise require external managed PDUs. Four of the six NEMA 5-15R outlets are software-programmable: you can configure them to shed non-critical loads when battery runtime falls below a threshold, freeing capacity for the essential devices; you can sequence power-on delays to prevent inrush current spikes when utility returns after an extended outage; or you can remotely reboot a locked-up switch or NVR without cycling power to the entire rack. The remaining two outlets are always powered whenever the UPS is on, ensuring critical devices like a firewall or core switch never lose power even during manual outlet group manipulation.
Active ECO mode is a field-selectable efficiency optimization that delivers line-interactive-like efficiency (up to 98%) while maintaining the protection level of double-conversion topology. In ECO mode, the UPS supplies load power directly from the bypass circuit during stable utility conditions, reducing internal heat generation and cutting energy waste. The rectifier and inverter remain powered and synchronized, monitoring input voltage and frequency every millisecond. If the utility drifts outside preset thresholds — even slightly — the UPS transfers to double-conversion mode in under 2 milliseconds, faster than line-interactive units and far faster than offline/standby designs. For integrators serving clients with strict uptime SLAs but also demanding LEED or Energy Star compliance, Active ECO mode closes the gap between reliability and sustainability.
Form factor versatility addresses the reality of modern network deployments: some racks are full-height 42U cabinets with rails and cable management, others are wall-mount 6U swing gates in a janitor closet, and still others are open shelving in a back office. The GXT5-750LVRT2UXL ships with both rack-mount ears and tower-stand feet. For rack installations, slide rails and L-brackets position the UPS in a standard 2U space; the gravity-sensing LCD detects the horizontal orientation and displays text right-side-up. For tower installations in equipment closets or under desks, attach the feet to the bottom panel, stand the UPS vertically, and the LCD reorients automatically. The 16.9-inch width fits standard 19-inch racks with room for cable bend radius; the 15.7-inch depth keeps the UPS within the footprint of shallow network cabinets common in security and A/V applications.
Connectivity options span basic USB monitoring to enterprise-grade SNMP integration. Every GXT5 includes a USB-B port for direct connection to a PC or NVR running shutdown software (Vertiv provides free monitoring utilities compatible with Windows, Linux, and common NAS operating systems). An RS232 serial port supports legacy equipment or building management systems that haven't migrated to IP-based monitoring. An RS485 port enables multi-drop daisy-chaining of up to 8 GXT5 units on a single monitoring cable, useful in distributed installations like campus security systems with a UPS in each building. Dry-contact terminal blocks provide hardwired alarm outputs for integration with fire panels, HVAC controllers, or facility monitoring systems that require volt-free contacts. For modern SNMP-based monitoring, the optional IntelliSlot RDU120 network interface card (sold separately) slides into the rear-panel slot and provides web-based management, email alerts, SNMP traps, remote outlet control, and environmental sensor inputs for temperature and humidity monitoring — all accessible from the same management platform you use for switches and servers.
The GXT5-750LVRT2UXL is third-party certified to UL 1778 4th edition and CSA 22.2 No. 107.1, meeting North American safety standards for stationary UPS systems, and carries ENERGY STAR 2.0 certification for energy efficiency, RoHS2 and REACH compliance for hazardous substance restrictions, and WEEE registration for responsible end-of-life recycling. Vertiv backs the unit with a three-year advanced replacement warranty covering the entire UPS including internal battery, with optional extended coverage available for installations requiring longer protection periods or next-business-day parts delivery.
