Vertiv GXT5-6KL630RT5UXLN 6KVA 208V On-Line Double Conversion UPS
The GXT5-6KL630RT5UXLN is a 4,900 VA / 4,600 W on-line double conversion UPS designed for 208V single-phase infrastructure where you need clean, regulated power without compromise. It accepts a wide 175–280 VAC input range — wide enough to ride through most utility sags without switching to battery — and delivers 200/208/220/230/240 VAC output that you configure at the panel. Whether you are powering a top-of-rack switch stack, a storage shelf, or a surveillance server room, this unit ships rack/tower convertible and is ready to manage the moment it lands.

Key Features
- On-line double conversion topology: Every watt of load runs through the inverter at all times — no transfer time, no micro-interruptions. Sensitive compute and storage see a perfectly clean sine wave regardless of what the utility is doing.
- 4,900 VA / 4,600 W capacity at 208V: Sized for a fully populated 5U blade chassis, a dense NVR stack, or a mixed server/storage pod. At 0.94 power factor, you are not leaving capacity on the floor.
- Up to 98% efficiency in Active ECO Mode: In ECO mode the load runs through a filtered bypass path; the inverter stays in hot standby. That cuts heat dissipation and operating cost meaningfully in a 24/7 data center or security operations center environment.
- 175–280 VAC wide input range: Covers the voltage swings common in older industrial buildings, generator-backed circuits, and international 200V/230V split environments without burning battery runtime on routine sags.
- Factory pre-installed Vertiv RDU101 SNMP/Webcard: Out of the box you get SNMP v1/v2/v3 and a web management interface — no additional card purchase, no slot juggling. Pairs directly with NMS platforms and pairs well with your network video recorders management stack.
- Configurable output voltage (200–240 VAC): One SKU handles a range of downstream equipment voltage requirements. Useful when standardizing a mixed-vendor rack without adding step-down transformers.
- Full-color gravity-sensing LCD: The display rotates to readable orientation whether the chassis is in tower or rack position. Status, load percentage, battery runtime, and input/output voltage are visible at a glance during install or troubleshooting.
- RS485, RS232, USB, terminal block interfaces: Serial out-of-band management covers the scenario where the network is down. Terminal block supports building automation integration or external transfer switch signaling.
- ENERGY STAR 2.0 certified, UL1778, c-UL listed: Satisfies utility rebate programs, meets North American safety listing requirements, and simplifies the sign-off process with facilities and compliance teams.
- Rack/tower convertible at 5U: Ships with hardware for both orientations. No separate tower base purchase. Useful for phased deployments where a rack is coming later.
Integration & Compatibility
The GXT5-6KL630RT5UXLN fits into standard 19-inch racks at 5U. The L6-30P input plug targets the 208V twist-lock circuits common in data center PDUs and raised-floor environments. Output receptacles — two L6-20R and two L6-30R — cover both 20A and 30A downstream loads on the same unit, which matters when mixing server PSUs with high-draw storage or GPU nodes. For broader UPS systems comparisons including tower-only and three-phase options, review the full category.
The factory RDU101 card speaks SNMP and HTTP, so integration with SolarWinds, PRTG, Nagios, or any RFC 1628 MIB-compatible NMS is straightforward. RS485 adds Modbus capability for building management system tie-ins. USB shutdown signaling covers single-server graceful shutdown scenarios without dedicating a network port. If you are designing a resilient infrastructure from scratch, pairing this with managed network switches on a separate UPS circuit is the standard practice. See the power protection guide for load calculation and runtime planning methodology.
Frequently Asked Questions
- What is the actual watt capacity of the GXT5-6KL630RT5UXLN, and how does that differ from the VA rating?
- The unit is rated 4,900 VA and 4,600 W. The watt figure reflects the 0.94 power factor. Size your load to 4,600 W maximum continuous; do not load to the full VA number for real-world power-consuming equipment.
- Does this UPS ship with a network management card, or is that a separate purchase?
- The Vertiv RDU101 SNMP and web card is factory pre-installed. SNMP and web management are enabled out of the box. No additional card is needed for standard network-based monitoring and shutdown.
- What input plug does this unit require, and what circuit breaker rating do I need?
- The unit uses an L6-30P input plug rated for 208V. You need a dedicated 30A, 208V circuit. Do not connect this to a standard 120V or 240V residential circuit — it is designed specifically for commercial 208V single-phase infrastructure.
- Can I configure the output voltage to match my downstream equipment?
- Yes. Output voltage is user-configurable at 200, 208, 220, 230, or 240 VAC. This is set via the LCD control panel. Confirm your downstream equipment's acceptable input range before changing from the default.
- What is the operating temperature range, and is it suitable for a non-air-conditioned space?
- The specified operating range is 0 to 40°C (32 to 104°F). Standard data center and IT room environments are well within spec. Warehouse or outdoor enclosure deployments near the upper limit should account for derating — battery life shortens materially above 25°C sustained.
- What certifications does this UPS carry, and does it qualify for utility efficiency rebates?
- The unit is ENERGY STAR 2.0 certified, UL1778 listed, c-UL listed, and complies with RoHS2 and REACH. ENERGY STAR 2.0 certification is the primary qualification criterion for most North American utility efficiency rebate programs — check your local utility's current program terms.
The GXT5-6KL630RT5UXLN sits in a useful spot in the 208V on-line UPS market: 4,600 W of double-conversion capacity with the RDU101 SNMP card already installed and ENERGY STAR 2.0 on the label. That last point is not just a compliance checkbox — it reflects the 98% ECO mode efficiency, which at continuous loads in a 24/7 environment translates to measurable annual kWh savings compared to older 92–93% efficient units of equivalent capacity.
Technical Highlights:
- 98% Active ECO / 95% on-line efficiency: At a 3,000 W continuous load, the difference between 98% and 92% efficiency is roughly 185 W of heat you are not pumping into the room — that is real cooling load reduction and real operating cost savings over a 3–5 year deployment.
- 175–280 VAC wide input window: This range is wide enough to stay on-line through generator start transients and building voltage sags without transitioning to battery. That matters for runtime preservation in sites with frequent utility events.
- Factory RDU101 card with SNMP v1/v2/v3: The card supports standard UPS MIB (RFC 1628) plus Vertiv's extended MIB. Integration with enterprise NMS platforms requires no extra licensing on the UPS side — just point your poller at the management IP.
Deployment Considerations:
- The L6-30P input requires a dedicated 208V/30A circuit at the rack. Verify your PDU or panel has this available before ordering — retrofitting a circuit in a live rack row has real lead time and cost implications.
- ECO mode introduces a brief transfer time to inverter if the bypass path detects an out-of-tolerance condition. For loads that are sensitive to any interruption (some older server PSUs, certain industrial controllers), verify tolerance before enabling ECO mode in production.
For a security operations center or edge data closet with a dense NVR and switch stack drawing 2,500–3,500 W at 208V, the GXT5-6KL630RT5UXLN is a straightforward fit: right capacity, right plug type, right management interface, ships ready to rack.
