Vertiv GXT5-3KL630RT2UXL 3KVA 208V Online Double-Conversion Rack/Tower UPS
The Vertiv GXT5-3KL630RT2UXL is a 3,000 VA / 3,000 W online double-conversion UPS running on 208 VAC with an L6-30P input — a serious power protection platform for small server rooms, edge deployments, and network equipment racks where utility power quality cannot be trusted. Unlike line-interactive designs that only switch to battery on significant sags, the GXT5's online double-conversion topology means every watt delivered to your load passes through the inverter continuously, providing zero-transfer-time battery backup and complete electrical isolation from the utility. If you're protecting surveillance NVRs, network switches, or application servers that cannot tolerate even millisecond interruptions, that distinction matters.
Key Features
- Online Double-Conversion Topology: All output power runs through the inverter at all times — no switching delay when utility fails. For network video recorders and access control servers that write continuously to disk, a transfer time of zero versus 8–20ms is the difference between clean operation and corrupted recordings.
- 3,000 VA / 3,000 W Power Rating (Unity Power Factor): Unity power factor means the VA and watt ratings are identical — no derating math needed. A 3,000 W load is a 3,000 W load. This is increasingly important as modern server PSUs pull closer to their nameplate wattage.
- 98% Efficiency in Active ECO Mode: In ECO mode the unit reaches 98% efficiency, reducing heat output and operating costs significantly over comparable designs running at 90–92%. On-line mode holds 95% — still strong for a full double-conversion design. ENERGY STAR 2.0 certified, so this efficiency claim is third-party verified, not a marketing number.
- Flexible Output Wiring (2x L6-15R + 2x L6-30R): The four output receptacles cover both 15A and 30A twist-lock equipment without adapters. A typical power and UPS deployment protecting a mixed rack — NVR, PoE switch, and a patch panel — can run all devices from a single unit without adapter chains that introduce failure points.
- Rack/Tower Convertible Form Factor (2U, 3.4" H × 16.9" W × 21.3" D): At 2U and 21.3 inches deep, it fits standard 4-post racks without overhanging the rails. The gravity-sensing LCD auto-orients whether the unit is racked horizontally or standing vertically — a practical detail when the same SKU gets deployed in different site configurations.
- Full-Color Graphic LCD with Gravity Sensing: The control panel rotates its display orientation automatically based on whether the unit is rack- or tower-mounted. Status, load percentage, battery runtime, and input/output voltage are readable without specialized tools or software — useful during initial commissioning and routine site checks.
- Multiple Interface Options (USB, RS485, RS232, Terminal Block, Optional SNMP): Out of box, USB and serial connections support local management and integration with server-based UPS clients (NUT, APC PowerChute equivalents). The optional Vertiv RDU101 SNMP/Webcard adds full SNMP and web-based remote monitoring — the right path if you're managing this unit as part of a larger network infrastructure stack monitored through NMS or DCIM software.
- External Battery Connector: The external battery connector allows runtime extension through compatible Vertiv EXB units without replacing the base UPS — a cost-effective path when runtime requirements grow after initial deployment.
- UL1778, c-UL, RoHS2, REACH, ENERGY STAR 2.0: UL1778 is the North American UPS safety standard; c-UL extends that recognition to Canada. RoHS2 and REACH compliance address EU material restrictions — relevant for any deployment with international regulatory documentation requirements.
Integration and Compatibility
The GXT5-3KL630RT2UXL communicates via USB and RS232/RS485 serial natively, making it compatible with most Linux and Windows UPS management daemons without additional hardware. The optional Vertiv RDU101 SNMP/Webcard (sold separately) slots into the communications bay to add full SNMP v1/v2/v3 and web-based monitoring — necessary if this unit needs to report into a centralized network management system or trigger graceful server shutdowns remotely. Serial out-of-band management via the terminal block provides a fallback path when IP connectivity is unavailable, which matters in edge deployments where network infrastructure itself may be on UPS-protected circuits.
Input requires a dedicated L6-30P circuit — confirm your panel has a 30A 208V two-pole breaker available before ordering. Output receptacles cover L6-15R and L6-30R twist-lock formats; standard NEMA 5-15/5-20 equipment requires appropriate adapters not included with this unit. At 65.1 lbs, two-person rack installation is the practical approach; plan lift assistance for elevated rack positions.
Frequently Asked Questions
Q: What input plug and circuit does the GXT5-3KL630RT2UXL require?
A: The GXT5-3KL630RT2UXL uses an L6-30P input plug, which requires a dedicated 30A, 208V two-pole circuit. Confirm your electrical panel has this circuit available before installation.
Q: Does the GXT5-3KL630RT2UXL include network (SNMP) management out of the box?
A: No. SNMP and web management require the optional Vertiv RDU101 SNMP/Webcard, which is not included. USB and RS232/RS485 serial management are available without any additional hardware.
Q: What is the transfer time to battery when utility power fails?
A: Zero. The GXT5-3KL630RT2UXL uses online double-conversion topology, meaning output power always runs through the inverter. There is no switching event when utility power is lost — connected equipment sees no interruption.
Q: Can the GXT5-3KL630RT2UXL be used as both a rack unit and a tower?
A: Yes. It ships in a convertible form factor that supports both rack (2U) and tower orientations. The full-color LCD uses gravity sensing to automatically rotate its display to the correct orientation for whichever mounting position is used.
Q: What certifications does the GXT5-3KL630RT2UXL carry?
A: It is ENERGY STAR 2.0 certified, UL1778 listed, c-UL listed (Canada), and compliant with RoHS2 and REACH.
Q: Can I extend the runtime of the GXT5-3KL630RT2UXL beyond the internal battery?
A: Yes. The unit includes an external battery connector that supports compatible Vertiv extended battery modules (EXB), allowing additional runtime without replacing the base unit.
The GXT5-3KL630RT2UXL hits a specific sweet spot in the Vertiv UPS line — 3,000 W at unity power factor with online double-conversion in a 2U footprint, running 208V with L6-30P input. That combination is not accidental: it's purpose-built for the edge rack scenario where you have real server or NVR loads, a 208V feed from a small PDU or panel, and no tolerance for transfer-time events. The 98% ECO mode efficiency is the number I flag to facilities teams — at full load over a year, the delta between 92% and 98% efficiency is real money on the power bill, and ENERGY STAR 2.0 certification means that figure has been independently validated.
Technical Highlights:
- Online Double-Conversion at 95–98% Efficiency: Running at 95% in on-line mode and up to 98% in ECO mode, this unit avoids the efficiency penalty that makes some double-conversion designs expensive to operate. The ECO mode 98% figure is competitive with line-interactive designs while retaining zero transfer time.
- Unity Power Factor (3,000 VA = 3,000 W): No derating calculation. If your load draws 2,800 W, you have 200 W of headroom — not a confusing VA-to-W conversion that under-counts actual capacity. Modern server PSUs and PoE switch power supplies almost universally draw close to their nameplate wattage.
- Four Twist-Lock Outputs (2x L6-15R + 2x L6-30R): The mixed outlet configuration means a standard edge rack with a 30A NVR or server draw plus 15A network equipment can be protected from a single UPS without adapter chains. That's a practical wiring win in tight installations.
Deployment Considerations:
- The L6-30P input is non-negotiable — this is not a unit you can run from a standard NEMA 5-20 or L5-30 circuit. Verify 30A 208V two-pole breaker availability in the target panel before procurement. In mixed-voltage facilities (120V and 208V infrastructure), misidentifying the available circuit is the most common installation error on this class of UPS.
- SNMP monitoring is a separate line item. If this unit needs to report into a central NMS or trigger graceful shutdowns on connected servers, budget for the Vertiv RDU101 card. The base unit ships with USB and serial only — plan accordingly in your BOM.
This unit is well-positioned for small surveillance or IT equipment rooms running 208V infrastructure — specifically where the rack holds an NVR, a PoE switch stack, and a server or two, and where the site has a 30A 208V circuit available. The rack/tower convertibility makes it a reasonable standard SKU across deployments that vary between dedicated server rooms (rack) and closet installations (tower).
