Vertiv GXT5-6000RT208 6000VA Online Double-Conversion Rackmount UPS
Overview
The Vertiv GXT5-6000RT208 is a 6000VA/5000W online double-conversion UPS engineered for 208V hardwire installations in data centers, server rooms, and critical infrastructure environments where utility power quality cannot be trusted. As part of the Vertiv GXT5 series, it delivers true double-conversion topology — every watt of connected load runs through the inverter continuously, meaning utility transients, sags, and frequency deviations never reach your equipment. That's the core reason to specify an online UPS over line-interactive in a rack environment where server warranties and SLAs are on the line.
The GXT5-6000RT208 (often searched as GXT5 6000RT208) is configured for 208V hardwire input and output, making it the correct fit for branch circuits in larger commercial and enterprise facilities that run 208V distribution rather than standard 120V receptacles. It also ships with compatibility for pre-installed GXT3 and GXT4 battery pods, which means you can extend runtime by adding external battery cabinets from prior-generation Vertiv GXT infrastructure — a meaningful consideration if you're refreshing an existing GXT3 or GXT4 deployment and want to reuse sunk battery investments.
Key Features
- 6000VA / 5000W Online Double-Conversion: full online topology means zero transfer time to battery — your power protection is active at all times, not on standby. Critical for servers and storage arrays that can't tolerate even a brief switchover gap.
- 208V Hardwire Input/Output: designed for direct hardwire connection to 208V branch circuits, eliminating the need for outlet-based distribution and enabling higher per-unit power density in the rack.
- GXT3/GXT4 Pod Compatibility: pre-installed support for legacy GXT3 and GXT4 external battery packs lets you extend runtime without purchasing entirely new battery infrastructure — relevant for phased refresh cycles in facilities already running GXT-generation equipment.
- Rackmount Form Factor: fits standard 19-inch equipment racks alongside the servers, switches, and storage it protects — no dedicated floor space, no separate power room required for smaller deployments.
Integration and Compatibility
The GXT5-6000RT208 integrates into rack environments built around 208V three-phase or single-phase 208V distribution. Verify your branch circuit amperage against the unit's input draw before installation — 6000VA at 208V pulls roughly 28.8A at unity power factor, so a 30A or 40A dedicated circuit is typically required depending on local electrical code derating. For network infrastructure racks or mixed compute/storage environments where runtime extension is a priority, the backward-compatible battery pod interface adds flexibility that a hard-replacement UPS cycle would not.
Frequently Asked Questions
Q: Is the GXT5-6000RT208 an online double-conversion UPS?
A: Yes. The GXT5-6000RT208 uses online double-conversion topology, meaning connected loads run through the inverter continuously with zero transfer time to battery — utility power never directly powers your equipment.
Q: What input voltage does the GXT5-6000RT208 require?
A: The GXT5-6000RT208 is configured for 208V hardwire input. It is not a standard 120V plug-in unit — installation requires a dedicated 208V branch circuit with appropriate breaker sizing.
Q: Can the GXT5-6000RT208 use existing GXT3 or GXT4 battery pods?
A: Yes. The GXT5-6000RT208 ships with pre-installed compatibility for GXT3 and GXT4 external battery pods, allowing runtime extension using prior-generation Vertiv battery infrastructure.
Q: What is the output power rating of the GXT5-6000RT208?
A: The GXT5-6000RT208 is rated at 6000VA / 5000W. Size your connected load to stay at or below 5000W to maintain proper operating margins.
Q: Is the GXT5-6000RT208 rack-mountable?
A: Yes. The GXT5-6000RT208 is designed for standard 19-inch rack installation, making it suitable for server room and data center rack deployments.
The GXT5-6000RT208 sits in a specific niche: 208V hardwire online UPS with backward compatibility to GXT3/GXT4 battery pods. If you're running a phased refresh of an older Vertiv GXT deployment, that pod compatibility is the reason to specify this unit over a clean-slate alternative — reusing existing battery cabinets offsets a meaningful portion of the capital cost.
Technical Highlights:
- Online Double-Conversion: zero transfer time to battery means even microsecond utility dropouts don't reach connected equipment — the right topology for any load where a brief power gap causes a reboot or data corruption event.
- 6000VA / 5000W Rating: provides headroom for a dense server or storage rack at 208V; keep actual load below 80% (4000W) for thermal and battery longevity margins.
- GXT3/GXT4 Pod Interface: pre-installed compatibility with prior-generation Vertiv external battery packs is a real cost lever in upgrade scenarios — budget for new pods only if runtime targets exceed what existing hardware can deliver.
Deployment Considerations:
- 208V hardwire means this unit requires a licensed electrician for installation — plan that into your project timeline and budget before the unit ships.
- At 6000VA / 208V, input current draw is approximately 28.8A at unity power factor; a 30A dedicated circuit may require derating under NEC 80% continuous load rules — confirm with your electrical contractor before circuit sizing.
Best fit for a server room refresh where an existing GXT3 or GXT4 battery cabinet is already racked and the facility runs 208V distribution — the GXT5-6000RT208 lets you upgrade the UPS head unit without scrapping the battery investment.
