Vertiv GXT5-5KL630RT3UXLN Online Double-Conversion Rack/Tower UPS
Overview
The Vertiv GXT5-5KL630RT3UXLN is a 4,900 VA / 4,600 W online double-conversion UPS built for rack or tower deployment in demanding environments where power quality is non-negotiable — think security command centers, network closets, and server rooms where any gap between utility failure and battery cutover is unacceptable. Unlike standby or line-interactive designs, double-conversion topology means your load runs off clean, inverter-generated power continuously; utility fluctuations, sags, surges, and brownouts never reach your equipment. At 5.25U and 34 inches deep, the GXT5-5KL630RT3UXLN fits a standard 2-post or 4-post rack without eating excessive real estate, and ships with the full communications card pre-installed — no separate accessories required to get SNMP and web management live on day one.
Key Features
- 4,900 VA / 4,600 W On-Line Double-Conversion Topology: The load never sees raw utility power — every watt passes through the rectifier and inverter continuously. That eliminates transfer time entirely, which matters for sensitive IP video recorders, network switches, and access control servers where even a 4ms interrupt can trigger a reboot or corrupt an in-progress write.
- Up to 98% Efficiency in Active ECO Mode: Running full on-line double-conversion at 95% efficiency is already competitive, but Active ECO mode pushes that to 98% — meaningful in a 24/7 data center or security operations center where the UPS runs for years. The difference between 95% and 98% on a 4,600 W load translates to roughly 138 W less heat and electricity draw continuously.
- L6-30P Input / Dual L6-20R + Dual L6-30R Output: The input plug is a NEMA L6-30P (208V, 30A), so you'll need a matching PDU receptacle or direct breaker feed — plan this before rack delivery. Outputs cover two L6-20R and two L6-30R receptacles, giving you flexibility to mix 20A and 30A downstream loads without a separate PDU adapter.
- 175–280 VAC Input Range: The wide input window handles everything from nominal 208V to the voltage sags common on lightly regulated building circuits. If your facility has documented brownout events, this range keeps the UPS on utility power longer before forcing a battery transfer — extending battery life and reducing discharge cycles.
- User-Configurable Output Voltage (200/208/220/230/240 VAC): Output voltage is selectable to match your load's requirements. For mixed deployments where some gear is spec'd for 220V or 230V international equipment, this eliminates step-down transformers.
- Factory Pre-Installed Liebert IntelliSlot RDU120 SNMP/Webcard: Most competitive units at this capacity ship the communications card as an optional add-on at $200–$400 extra. The RDU120 is already installed — SNMP traps, web dashboard, and email alerting are available the same day you commission the unit. RS485, RS232, USB, and terminal block connections round out the interface options for legacy BMS or building automation integration.
- Full-Color Graphic LCD with Gravity-Sensing Orientation: The panel reorients its display automatically when you switch between rack and tower mounting. That's a practical detail — no hunting for a setting buried in a menu when you flip the unit during a rack buildout.
- ENERGY STAR 2.0 / UL1778 / c-UL / RoHS2 / REACH Listed: ENERGY STAR 2.0 certification satisfies green-building and procurement mandates at government and enterprise accounts. UL1778 is the standard listing for UPS equipment in North America — required for most commercial and government installation permits.
- Operating Range +32 to +104°F (0 to 40°C): Standard data center thermal envelope. If your equipment room runs hot — above 95°F routinely — factor in derating; most UPS units reduce available capacity above 40°C.
- 122 lbs, 5.25U Rack Form Factor: At 122 lbs, this needs a two-person lift or a rack lift tool. Plan for rear support rails and verify your rack's weight capacity — 122 lbs plus attached cabling on a 5U shelf requires at minimum a mid-weight rack rated to 1,000 lbs or better.
Integration and Compatibility
The factory-installed Liebert IntelliSlot RDU120 card provides SNMP v1/v2/v3 and web management out of the box. For BMS or DCIM integration, RS485 and RS232 ports support legacy serial protocols. USB connects directly to a host for software-based shutdown (UPS management software, vendor NMC tools). The external battery connector supports runtime extension via compatible external battery cabinets — useful in security operations centers where extended outages must be survived without a generator. The GXT5-5KL630RT3UXLN also carries c-UL listing, making it deployable in Canadian facilities without additional evaluation.
Frequently Asked Questions
Q: What is the input plug type for the GXT5-5KL630RT3UXLN, and what circuit does it require?
A: The GXT5-5KL630RT3UXLN uses a NEMA L6-30P input plug, which requires a 208V, 30A dedicated circuit. Verify your rack PDU or panel has an L6-30R receptacle before installation.
Q: Does the GXT5-5KL630RT3UXLN include a network management card, or is it a separate purchase?
A: The Liebert IntelliSlot RDU120 SNMP/Webcard is factory pre-installed. SNMP and web management are available immediately without purchasing an additional card.
Q: Can the GXT5-5KL630RT3UXLN be installed in both rack and tower orientations?
A: Yes. The flexible rack/tower form factor supports both orientations, and the full-color graphic LCD includes gravity-sensing orientation so the display automatically adjusts when the unit is repositioned.
Q: What output voltage options are available on the GXT5-5KL630RT3UXLN?
A: Output voltage is user-configurable to 200, 208, 220, 230, or 240 VAC, allowing the UPS to match the requirements of different downstream equipment without a step-down transformer.
Q: What certifications does the GXT5-5KL630RT3UXLN carry?
A: The unit is ENERGY STAR 2.0 certified, UL1778 listed, c-UL listed, and complies with RoHS2 and REACH regulations.
Q: Does the GXT5-5KL630RT3UXLN support external battery expansion?
A: Yes. An external battery connector is included, allowing connection to compatible external battery cabinets for extended runtime beyond the internal battery capacity.
The GXT5-5KL630RT3UXLN is one of the few units in this capacity range that ships with the SNMP/Webcard already installed — in a typical security operations center or network room deployment, that alone saves a procurement cycle and $200–$400 in add-on hardware. The 98% Active ECO efficiency is genuinely competitive at 4,900 VA; at 24/7 runtime on a 4,600 W load, you're looking at roughly 138 W of continuous savings compared to a 95% on-line topology unit — that adds up over three to five years of runtime.
Technical Highlights:
- On-Line Double-Conversion at 4,900 VA / 4,600 W: Zero transfer time to battery — the load never sees utility voltage directly. Critical for IP video recorders and access control servers where a 4ms gap causes reboots or write corruption.
- 98% ECO / 95% On-Line Efficiency: Meaningful in always-on deployments. The 3-point efficiency gap on a 4,600 W continuous load is approximately 138 W — reduces heat, cooling load, and electricity cost without sacrificing protection level.
- 175–280 VAC Input Window: Wide enough to ride through the brownouts common on older commercial building infrastructure without unnecessarily cycling to battery — extends battery service life in facilities with known voltage sag events.
Deployment Considerations:
- The L6-30P input requires a dedicated 208V/30A circuit with an L6-30R receptacle. Confirm panel capacity and PDU compatibility before the unit ships — retrofitting a circuit after rack delivery is a project delay, not a minor adjustment.
- At 122 lbs, this is a two-person or mechanical-lift installation. Verify rack weight ratings before placing — a fully cabled 5U UPS at the rear of a mid-tower rack can exceed the rail weight limit on lighter consumer or prosumer racks.
This unit fits best in a security command center, colocation cage, or enterprise network room running 208V infrastructure where DCIM/BMS integration via SNMP is required on day one and efficiency at continuous load matters for operating cost over a multi-year deployment cycle.
