Vertiv GXT5-500LVRT2UXL Online Double-Conversion 500VA/500W Rack/Tower UPS
Overview
The GXT5-500LVRT2UXL is Vertiv's Liebert GXT5-series 500VA/500W online double-conversion UPS in a 2U rack/tower convertible form factor — built for edge IT closets, surveillance NVR racks, and small server rooms where power quality problems (sags, surges, noise, frequency drift) are as much a risk as outright outages. Unlike standby or line-interactive designs that switch to battery only when utility power fails, the GXT5-500LVRT2UXL runs your load continuously off its inverter. Utility power feeds the battery; the battery feeds the inverter; the inverter feeds your equipment — no transfer time, no switching transient, no gap for sensitive electronics to notice. If you're protecting NVRs, edge servers, or networked access control panels, this architecture eliminates the class of reset/reboot events that line-interactive UPS units can't prevent.
Key Features
- Online Double-Conversion Topology: Every watt your equipment draws passes through the inverter continuously — zero transfer time to battery means no switching event when utility power drops or degrades. NVRs and IP cameras with PoE switches can't tolerate even 10–20ms transfer gaps reliably; this eliminates that failure mode entirely.
- Pure Sinewave Output: The inverter synthesizes a clean 60Hz pure sinewave at your configured output voltage (110, 115, 120, or 125VAC ±3%, user-selectable). Active PFC power supplies — standard in modern servers, NVRs, and managed switches — require a true sinewave to operate correctly. Modified-sinewave UPS units cause audible buzz, overheating, and premature failure in these loads.
- Hot-Swappable VRLA Batteries: Battery replacement doesn't require powering down the load. In a 24/7 surveillance or access control environment, scheduled maintenance windows are inconvenient at best. Pull the spent battery, slide in a replacement, and the UPS keeps your equipment online throughout.
- 6 x NEMA 5-15R Outlets (4 Programmable): Four of the six outlets are individually programmable for sequenced power-on and load-shed events — useful when you need to bring up an NVR before its cameras, or shed non-critical loads (workstations, monitors) while keeping recorders and network gear alive during extended outages.
- Color LCD Display: Real-time readout of load percentage, estimated runtime, input/output voltage, and battery health — no need to poll management software to know your headroom. Useful during initial commissioning to confirm the load is within operating range before relying on runtime estimates.
- USB + RS485 + RS232 + Optional RDU101 Network Card: Out of the box, the GXT5-500LVRT2UXL connects to a host via USB or serial for graceful shutdown via PowerAlert, Windows Server, Linux, or VMware. The optional RDU101 network card slot adds SNMP/web management for remote monitoring — important if the UPS is in an unattended IDF closet or remote surveillance enclosure.
- Energy Star 2.0 Certified, >92% Efficiency at 50% Load: Running a 500W UPS at roughly 250W load is typical for small NVR + switch deployments. At that load point, efficiency exceeds 92%, meaning less than 20W lost to heat — relevant in tight rack enclosures where thermal headroom is limited.
- Wide Input Voltage Range (60–150V): The rectifier accepts utility input anywhere from 60V to 150V before switching to battery. In older buildings or locations with chronic undervoltage, this range means the UPS stays on utility longer before drawing down battery — extending runtime capacity for actual outage events.
- UL 1778 4th Ed. / CSA 22.2 No. 107.1 Certified: Required for commercial and institutional installations. These certifications confirm the unit has been tested to recognized North American safety standards — relevant for insurance, AHJ inspection, and enterprise procurement requirements.
- RoHS2 and REACH Compliant: Matters for government, healthcare, and education installations where environmental compliance documentation is part of the procurement process.
Integration and Compatibility
The GXT5-500LVRT2UXL (often searched as GXT5 500LVRT2UXL) integrates with Vertiv's PowerAlert Local software for single-unit graceful shutdown, or PowerAlert Network Management System for multi-UPS monitoring. Native compatibility with VMware vCenter, Windows Server UPS services, and Linux NUT (Network UPS Tools) means integration into existing infrastructure management workflows without additional middleware. The optional RDU101 network card enables SNMP traps and a web-based management interface for remote status and alerting — the right path for surveillance closets or remote sites without on-site IT staff. At 2U and 17 inches wide, it fits standard 19-inch rack rails; the included tower stand allows free-standing deployment alongside rack equipment in mixed environments.
Frequently Asked Questions
Q: What is the transfer time to battery on the GXT5-500LVRT2UXL?
A: Zero. The GXT5-500LVRT2UXL uses online double-conversion topology, meaning your load runs continuously off the inverter. There is no transfer time — utility power loss causes no switching event or interruption to connected equipment.
Q: Can the GXT5-500LVRT2UXL run active PFC power supplies?
A: Yes. The inverter produces a pure sinewave output, which is required for active PFC power supplies found in modern servers, NVRs, and managed network switches. Modified-sinewave UPS units are not suitable for these loads.
Q: What is the runtime on the GXT5-500LVRT2UXL at typical loads?
A: At 50% load (approximately 250W), expect 15–18 minutes of runtime. At 80% load (approximately 400W), expect 8–10 minutes. Runtime varies based on battery age, temperature, and actual connected load.
Q: Does the GXT5-500LVRT2UXL support network monitoring without a separate server?
A: The base unit includes USB, RS485, and RS232 for local host-based management. For network-based SNMP/web monitoring without a connected host, the optional RDU101 network card must be installed in the provided expansion slot.
Q: What is the warranty on the GXT5-500LVRT2UXL?
A: The GXT5-500LVRT2UXL carries a 3-year advanced replacement warranty with full coverage per the manufacturer's terms.
Q: Is the GXT5-500LVRT2UXL rack-mountable?
A: Yes. It is a 2U rack/tower convertible unit designed for standard 19-inch racks. It can also be deployed as a tower unit using the included stand for non-rack environments.
The spec that matters most in a surveillance or access control rack isn't VA capacity — it's topology. The GXT5-500LVRT2UXL runs online double-conversion, which means zero transfer time to battery and continuous power conditioning on every cycle. I've seen line-interactive units cause NVR reboots during voltage sags that never even interrupted utility power — the switching transient alone was enough. That failure mode doesn't exist with this unit.
Technical Highlights:
- Zero Transfer Time: Continuous inverter operation means no switching event under any utility condition within the 60–150V input range — NVRs, PoE switches, and access control panels stay online through sags, surges, and outages without exception.
- Pure Sinewave Output: Inverter-synthesized 60Hz sinewave at 110/115/120/125VAC (user-configurable, ±3%) — compatible with active PFC loads that will fault or overheat on modified-sinewave UPS units.
- Hot-Swap Batteries: VRLA battery replacement without load shutdown is non-negotiable in 24/7 environments. Three-year warranty with advanced replacement reduces the risk of being caught with a degraded battery bank and no coverage.
Deployment Considerations:
- The base unit ships without the RDU101 network card — USB or serial management only out of the box. If this UPS is going into an unattended closet or remote site, budget the RDU101 at the time of purchase, not after the fact when you need remote visibility.
- At 500VA/500W capacity, this unit is sized for a single NVR plus a small PoE switch or a handful of edge devices — not a full rack of servers. Verify your actual load with a power meter before commissioning; online double-conversion has no headroom forgiveness when you're running close to rated capacity.
The GXT5-500LVRT2UXL is the right fit for a single-rack surveillance deployment — one NVR, one managed PoE switch, one access control panel — where power quality is a documented problem or the site is on aging electrical infrastructure. It's overkill as a desktop UPS and undersized for a server room; in that specific edge rack scenario, the double-conversion topology earns its price premium over a line-interactive alternative.
