Vertiv GXT5-3KL620RT2UXL 3000VA 208V Online Double Conversion Rack/Tower UPS
Overview
The Vertiv GXT5-3KL620RT2UXL is a 3000VA / 3000W online double-conversion UPS purpose-built for 208V L6-20P environments — the kind of load you see in server rooms, network closets, edge deployments, and security operations centers where unfiltered utility power is not an option. At 2U and 65.1 lb, it installs in a standard rack or sits in tower orientation without a separate enclosure purchase. The full-color gravity-sensing LCD rotates its display automatically whether you mount it horizontally or vertically — a small detail that matters when you're commissioning equipment in a mixed rack/tower environment.
This is an on-line double-conversion design, meaning your connected equipment never runs on raw utility power. The inverter is always active, delivering a continuously regulated 208 VAC output regardless of what the input is doing. That's the correct topology for protecting sensitive electronics from voltage sags, surges, frequency instability, and complete outages — and it's why the GXT5-3KL620RT2UXL earns its place ahead of line-interactive or standby-mode alternatives in critical infrastructure deployments.
Vertiv's UPS and power protection line covers a broad range of rack-mount and standalone configurations; the GXT5 family sits in the 1–10 kVA range targeted at mid-density IT and security infrastructure loads.
Key Features
- 3000VA / 3000W Unity Power Factor: A 1.0 power factor means the VA and watt ratings are identical — no derating required when calculating real load. Size your protected devices against the 3000W ceiling directly, without the 0.6–0.8 PF correction factor that trips up engineers on older UPS designs.
- 98% Efficiency in Active ECO Mode: Active ECO mode cuts heat output and reduces operating costs versus the 95% on-line baseline. On a 3kW load running continuously, the difference between 95% and 98% efficiency is roughly 90W of additional heat — meaningful in high-density racks where every watt of dissipation competes for cooling capacity.
- On-Line Double Conversion Topology: The inverter is always in the output path; there is zero transfer time on a utility failure. For NVR arrays, access control servers, or edge compute nodes that cannot tolerate even a 4–8ms gap, this is the only topology that qualifies.
- L6-20P Input / Mixed L6-15R and L6-20R Outputs: The input draws from a single L6-20P source (standard 208V 20A circuit). The output bank provides 2× L6-15R and 2× L6-20R receptacles, which covers the mix of 15A and 20A loads typical in small server and security infrastructure racks without requiring plug adapters on most equipment.
- ENERGY STAR 2.0 Certified: This certification reflects measured efficiency performance — not a marketing claim — which matters for LEED-targeted facilities, government procurement, and any deployment where the facility manager reviews power consumption at commissioning.
- Full-Color Gravity-Sensing LCD: The control panel detects its own orientation and rotates the display accordingly. During a rack installation, you get a readable status panel whether the unit is lying flat on a bench, installed horizontally, or in tower orientation — no menu diving to flip the display.
- Flexible Communications Architecture: Built-in USB, RS485, RS232, and terminal block cover direct-connect management scenarios out of the box. Add the optional Vertiv RDU101 SNMP/Webcard to integrate into network management platforms for remote monitoring, alerting, and graceful shutdown orchestration across a managed environment.
- Operating Range +32 to +122°F (0–50°C): The upper 50°C limit provides headroom for equipment closets that are not actively cooled to data center standards. Useful in edge deployments — retail back-of-house, warehouse network cabinets, or building automation nodes — where ambient temperature can climb in summer months.
- UL1778 / c-UL Listed, RoHS2, REACH: UL1778 is the North American standard for UPS equipment. c-UL covers Canadian deployments. RoHS2 and REACH compliance supports EU procurement, cross-border installations, and responsible materials sourcing requirements that appear in enterprise and government RFPs.
Integration and Compatibility
The GXT5-3KL620RT2UXL connects to monitoring infrastructure via USB or serial (RS232/RS485) natively. For managed environments, pair with the optional Vertiv RDU101 communications card to expose SNMP traps and a web management interface — this is the standard path for integrating UPS events into data center infrastructure management (DCIM) platforms, VMware, or network management systems that trigger graceful VM or server shutdown before battery exhaustion.
The external battery connector supports runtime extension with compatible Vertiv EBM (Extended Battery Module) cabinets, useful in deployments where the standard battery runtime is insufficient for the expected utility outage window. Review the UPS accessories category for compatible battery expansion options.
For security system deployments, this unit pairs naturally with network video recorders and their attached storage — protecting the recording infrastructure that is often the last thing operators want to lose during a power event. It also complements PoE switches feeding camera infrastructure, where a power interruption would take down both the switch and its downstream cameras simultaneously.
When scoping your installation, consult a UPS sizing guide to verify that your actual load — accounting for inrush current from camera arrays and NVR drives — stays within the 3000W ceiling at the duty cycle you intend to run.
Frequently Asked Questions
Q: What input plug does the GXT5-3KL620RT2UXL require, and what circuit should I provision?
A: The unit uses an L6-20P input, which requires a dedicated 208V 20A circuit with a NEMA L6-20R receptacle. Ensure your facility wiring supports 208V (not 120V) before ordering — this unit is not designed for single-phase 120V environments.
Q: Does the GXT5-3KL620RT2UXL support remote SNMP management out of the box?
A: No. SNMP and web management require the optional Vertiv RDU101 SNMP/Webcard, which is not included. The unit ships with USB, RS232, RS485, and terminal block interfaces for direct-connect management. The RDU101 card is a separate purchase.
Q: What output receptacles are on the GXT5-3KL620RT2UXL?
A: The unit provides 2× L6-15R and 2× L6-20R output receptacles — all 208V. Plan your equipment plug types accordingly. If your equipment uses L6-30P or other configurations, you will need appropriate power distribution or adapters.
Q: Can the GXT5-3KL620RT2UXL be used in a hot environment like an equipment closet?
A: Yes. The operating temperature range is +32 to +122°F (0 to 50°C), which provides tolerance for unconditioned or lightly cooled equipment closets. Sustained operation near the upper limit will reduce battery life over time — verify adequate airflow around the unit.
Q: Is the GXT5-3KL620RT2UXL ENERGY STAR certified?
A: Yes — it carries ENERGY STAR 2.0 certification, reflecting independently measured efficiency performance. In Active ECO mode, efficiency reaches up to 98%.
Q: Can the GXT5-3KL620RT2UXL be rack-mounted and tower-mounted?
A: Yes. The design supports both rack and tower installation. The full-color LCD uses gravity sensing to automatically orient its display correctly in either configuration.
The GXT5-3KL620RT2UXL is one of the cleaner options in the 3kVA 208V rack-mount segment precisely because of its unity power factor: when you calculate protected load, 3000W is 3000W with no derating math. That eliminates a common commissioning mistake where integrators size against the VA rating and discover headroom has been consumed by PF correction on the actual watt draw.
Technical Highlights:
- Double Conversion / Zero Transfer Time: No transfer gap on utility failure — critical for NVR recording continuity and access control server uptime where even a brief power dropout triggers card reader resets or lost video segments.
- 98% ECO Mode Efficiency: At 3kW continuous load, the 3-point efficiency gain over standard on-line mode saves roughly 90W of heat generation — that's meaningful in a tight IDF closet without dedicated precision cooling.
- Built-in RS232/RS485 + Optional RDU101: The native serial ports cover direct UPS-to-server shutdown wiring today; the RDU101 card slot gives you a clear upgrade path to full SNMP/web integration when the site's network management requirements mature.
Deployment Considerations:
- The L6-20P input is 208V-specific — confirm the circuit before installation. Facilities running a mix of 120V and 208V drops have been burned by this on security system deployments where the camera/NVR rack was assumed to be on the same voltage as the rest of the building.
- The unit weighs 65.1 lb. Rack installation is a two-person job — plan accordingly and verify your rack rail kit is rated for the weight before commissioning day.
This unit is well-suited for edge security infrastructure nodes — specifically a 2U slot in a rack housing an NVR, managed PoE switch, and access control server in a facility with 208V distribution. The 50°C operating limit and gravity-sensing display make it serviceable in warm equipment closets where a conventional data center UPS would be overkill on footprint and cost.
