Vertiv GXT5-5000MVRT4UXLN Online Double-Conversion Rack/Tower UPS
Overview
The Vertiv GXT5-5000MVRT4UXLN is a 5,000 VA / 5,000 W online double-conversion UPS designed for server rooms, network closets, and security infrastructure that cannot tolerate even milliseconds of power interruption. Unlike line-interactive or standby units that switch to battery only when voltage falls outside a window, the GXT5 runs your load continuously through a fully regulated inverter — the battery is always in the circuit, so switchover time is zero. If you're protecting NVRs, access control servers, or VoIP infrastructure where a 20ms transfer gap causes equipment resets, that topology difference matters.
The GXT5-5000MVRT4UXLN ships in a flexible rack/tower form factor at 4U height (6.8 in), 16.9 in wide, and 25.6 in deep — fits a standard 19-inch rack or stands upright in a wiring closet. Input and output are hardwired, not plug-and-socket, which is appropriate for this power class and simplifies compliance with electrical codes in commercial installations. For sites that need receptacle-based output, optional Power Output Distribution (POD) modules are available separately.

Key Features
- Online Double-Conversion Topology: The load runs off the inverter output 100% of the time, not the raw utility feed. Voltage spikes, sags, frequency drift, and complete outages are all handled without any transfer gap — critical for equipment with tight power tolerance like managed switches and NVR storage arrays.
- 5,000 VA / 5,000 W at Unity Power Factor: A 1.0 power factor means the VA and watt ratings are identical — no derating penalty when sizing for real-world IT loads, which are predominantly resistive/switching. Size your connected load to 80% of capacity (4,000 W) to leave headroom for startup inrush and future expansion.
- 208/120VAC User-Configurable Output: Output voltage is selectable between 208V and 120V, letting one SKU serve either a standard 20A/120V branch circuit environment or a 208V two-phase panel common in data center rows. Verify your downstream equipment voltage requirements before commissioning — misconfiguration here will damage connected loads.
- 176–280VAC Wide Input Range: The unit accepts input from 176V to 280VAC before falling back to battery, which accommodates browndowns common in older commercial buildings and generator-backed systems that run slightly off nominal. Typical input is 208VAC.
- Up to 98% Efficiency in Active ECO Mode: In ECO mode the unit bypasses the inverter when utility power is clean, dropping losses to roughly 2%. On-line mode runs at up to 95%. For a 5kW load running 8,760 hours per year, the difference between 95% and 98% efficiency translates to roughly 1,314 kWh annually — real operating cost savings in a co-located or multi-UPS environment.
- Factory-Installed Vertiv RDU101 SNMP/Webcard: SNMP and web management are active out of the box — no optional card to purchase and install separately. The RDU101 exposes UPS status to your NMS, enables email/SNMP trap alerting on events like battery low or overload, and supports graceful OS shutdown agents via standard protocols. USB and RS232/RS485 serial ports provide redundant management paths and out-of-band access.
- Full-Color Gravity-Sensing LCD Panel: The control panel reads orientation automatically — the display rotates to remain readable whether the unit is rack-mounted horizontally or standing vertically in tower mode. This is a small but practical detail during installation when orientation may change before final positioning.
- ENERGY STAR 2.0 Certified, UL1778, c-UL Listed: ENERGY STAR certification is relevant for organizations tracking facility efficiency or pursuing LEED credits. UL1778 and c-UL listings confirm the unit has been independently evaluated for electrical safety — a baseline requirement for most data center and commercial building insurance and inspection programs. RoHS2 and REACH compliance are required for many government and institutional procurement contracts.
- External Battery Connector: The interface panel includes an external battery connector, allowing additional UPS battery packs to be connected for extended runtime without replacing the base unit. This is the right architecture for surveillance deployments where you need to outlast a multi-hour utility outage, not just bridge a momentary gap.
Integration and Compatibility
The factory-installed RDU101 card supports SNMP v1/v2/v3 and HTTP/HTTPS web interface — compatible with major NMS platforms including SolarWinds, PRTG, and Nagios via standard MIB. Serial connections via RS232 and RS485 support out-of-band management from a terminal server when network access is unavailable. The USB port supports integration with server-based shutdown software on Windows, Linux, and macOS hosts.
The hardwired input/output requires a licensed electrician for installation. Input conductor sizing should account for the 208VAC nominal at 5kVA — confirm panel capacity and breaker sizing with your electrical contractor before installation. If your facility runs 120V branch circuits exclusively, confirm the output voltage configuration is set appropriately before connecting loads.
For integrated NVR and server rack deployments, pair with a Vertiv PDU for per-outlet metering and remote switching downstream of this UPS. For network switch protection in the same rack, confirm PoE switch power draw against your 4,000W recommended operating load ceiling.

Frequently Asked Questions
Q: What is the difference between the GXT5-5000MVRT4UXLN's on-line mode and Active ECO mode?
A: In on-line (double-conversion) mode, all power to the load flows through the rectifier and inverter continuously — no transfer time on outage, full isolation from utility disturbances, efficiency up to 95%. In Active ECO mode, the unit bypasses the inverter when utility power is within spec, improving efficiency to up to 98%, but introduces a brief transfer to inverter if utility power degrades. For loads that require absolute zero-transfer protection, run in on-line mode. ECO mode is appropriate for less sensitive loads where the efficiency gain outweighs the marginal transfer risk.
Q: Is the GXT5-5000MVRT4UXLN hardwired or does it use standard plug connections?
A: Both input and output are hardwired — there are no NEMA plug connections on the base unit. Installation requires a licensed electrician. Optional Power Output Distribution (POD) modules are available separately if you need receptacle-based output for connected equipment.
Q: Does the GXT5-5000MVRT4UXLN include an SNMP card, or is that a separate purchase?
A: The Vertiv RDU101 SNMP/Webcard is factory pre-installed. SNMP and web management are enabled out of the box — no additional card purchase is required. USB, RS232, and RS485 ports are also included for alternate management paths.
Q: Can the GXT5-5000MVRT4UXLN be used in both rack and tower configurations?
A: Yes. The unit ships in a flexible rack/tower form factor. The full-color LCD panel includes gravity-sensing orientation that rotates the display automatically to remain readable in either mounting position.
Q: What input voltage range does the GXT5-5000MVRT4UXLN accept before switching to battery?
A: The unit accepts input from 176VAC to 280VAC before falling back to battery, with a typical operating input of 208VAC. This wide range accommodates voltage sags common in commercial buildings and generator-backed utility environments.
Q: Can I expand the runtime of the GXT5-5000MVRT4UXLN with external battery packs?
A: Yes. The unit includes an external battery connector on the interface panel, allowing compatible Vertiv extended battery modules to be added for increased runtime beyond what the internal battery provides.
The GXT5-5000MVRT4UXLN is one of the more deployment-ready 5kVA units I've worked with — the factory-installed RDU101 SNMP card is a meaningful differentiator at this price point. Most competitors at this class require a separate network management card purchase and field installation. Here it's live out of the box, which shortens commissioning time on rack builds where you're simultaneously bringing up NVRs, access control servers, and managed switches.
Technical Highlights:
- Unity Power Factor (5,000 VA = 5,000 W): No derating math required when sizing — 5kVA delivers 5kW to the load. This matters because legacy UPS specs at 0.8 PF would only yield 4,000W from the same VA rating, forcing an upsize for the same actual load.
- 98% ECO / 95% On-Line Efficiency: At a 5kW continuous load, the 3-point efficiency gap between modes is roughly 150W of heat rejection per hour — meaningful in a sealed equipment cabinet or small IDF where thermal management is already tight.
- 176–280VAC Input Range: That's a 104VAC acceptance window around the 208V nominal. In practice, generator startup transients and browndowns that would force a lesser unit onto battery won't affect this one — the rectifier just rides through.
Deployment Considerations:
- Hardwired input and output means this is not a drop-in swap for plug-based UPS installations. Factor licensed electrical labor into your project budget. If receptacle outputs are needed downstream, quote the POD modules at the same time as the base unit.
- At 125.6 lb, two-person lift is required for rack installation. Confirm your rack rail kit is rated for this weight class before mounting — the unit is 25.6 inches deep, which will overhang shallow 4-post racks.
This unit fits best in a purpose-built security or IT rack where the load is a mix of NVRs, PoE switches, and access control servers drawing 3,000–4,000W continuous — leaving the recommended 20% headroom while running in on-line mode for zero-transfer protection. Facilities running older 208V panel infrastructure with voltage quality issues will also benefit from the wide input acceptance window over a narrower-spec alternative.
