Vertiv ITA2-80KRT400V37UPRN 40kVA 2+1 Redundant Parallel Three-Phase Online UPS
Overview
The Vertiv Liebert ITA2-80KRT400V37UPRN is a 40kVA/40kW rack/tower-convertible uninterruptible power supply configured as a 2+1 redundant parallel bundle for three-phase 400VAC (240VAC) environments. It uses true online double-conversion technology to continuously condition and regulate output voltage — meaning every connected load runs on clean, synthetic sine-wave power at all times, not just during a mains event. This is the configuration for server rooms, data halls, network closets, and security operations infrastructure where a single UPS failure cannot be allowed to interrupt critical loads. The bundle includes VRLA (valve-regulated lead-acid) battery pairs and SNMP management, making it a complete, rack-ready power protection solution for IT and physical security deployments.

Key Features
- True Online Double-Conversion at 40kVA/40kW: Unlike line-interactive or standby designs, double-conversion continuously regenerates output from the DC bus — there is zero transfer time on mains failure. For server infrastructure or surveillance recording arrays where even a 20ms gap causes a reboot or dropped recording, this architecture eliminates that risk entirely.
- 2+1 Redundant Parallel Architecture: The bundle ships configured so two UPS units carry the load while a third stands by. If any single unit fails, the remaining two absorb the load without interruption. This is N+1 redundancy at the UPS layer — the design choice for facilities that cannot schedule maintenance windows or tolerate single points of failure in their power path.
- Unity Power Factor (1.0): A 1.0 power factor means the rated kVA and kW figures are identical — 40kVA delivers 40kW of usable real power. Many UPS units carry a 0.8 or 0.9 power factor, which forces you to oversize the UPS to get your required wattage. Here, every watt of capacity is available to your load, simplifying sizing calculations.
- 99% Efficiency in ECO Mode: In double-conversion mode efficiency exceeds 93%, which is competitive for online UPS at this class. ECO mode pushes efficiency to 99% — a meaningful reduction in heat dissipation and operating cost across a 40kW system running continuously. On a system drawing near full load 24/7, even a few percentage points of efficiency improvement translates to thousands of dollars annually in energy costs.
- VRLA Hot-Swappable Batteries: The valve-regulated lead-acid battery design is user-replaceable without powering down the protected load — critical in a 2+1 parallel bundle where battery maintenance on one unit while the others hold the load is a standard operational procedure. No scheduled downtime is required for routine battery service.
- SNMP Network Management: Built-in SNMP allows integration with existing network management platforms and data center infrastructure management (DCIM) tools. You can monitor UPS status, battery health, load percentage, and alarm conditions remotely — essential for unmanned equipment rooms or multi-site deployments where a technician is not on-site.
- ENERGY STAR 2.0 Certified: At 40kW continuous, ENERGY STAR 2.0 certification matters for organizations subject to data center efficiency mandates or sustainability reporting. It also directly reduces operating costs and can qualify the installation for utility rebate programs depending on jurisdiction.
- Rack/Tower Convertible Form Factor: The physical chassis converts between rack-mount and tower orientations, giving installation teams flexibility to deploy in standard 19-inch equipment racks or as standalone tower units depending on the facility layout — without purchasing a separate chassis.
- Scalable Battery Runtime: The VRLA battery configuration supports scalable runtime extension, allowing additional external battery modules to be added as load requirements or runtime targets change over the deployment lifecycle.
Integration and Compatibility
The ITA2-80KRT400V37UPRN operates on 400VAC three-phase four-wire input, which is the standard distribution voltage for European and international commercial facilities and increasingly common in US data center deployments. The SNMP card enables integration with BMS platforms, NMS tools, and vendor-specific management software for consolidated monitoring. The parallel bus architecture supports up to 4+1 configurations beyond this 2+1 bundle if capacity needs to scale. For facilities using managed network infrastructure, SNMP polling can be configured alongside switch and access layer monitoring in a unified dashboard. Pairing this UPS with a rack-mount PDU downstream provides per-outlet monitoring and switching at the load level, completing a fully managed power chain.

Frequently Asked Questions
Q: What is the difference between the 40kVA rating and the actual usable power output of the ITA2-80KRT400V37UPRN?
A: The ITA2-80KRT400V37UPRN has a unity power factor of 1.0, which means the kVA and kW ratings are identical — 40kVA equals 40kW of real usable power. Many UPS systems carry a 0.8 or 0.9 power factor, reducing usable watts below the kVA nameplate. Here, there is no derating to account for.
Q: How does the 2+1 parallel redundancy work in this bundle?
A: In a 2+1 configuration, two UPS units actively share the load while a third unit remains online as a standby. If any single unit faults or requires maintenance, the remaining two units absorb the full load without a transfer event. This provides N+1 redundancy at the UPS level, protecting against single-unit failure.
Q: Can batteries be replaced without shutting down the protected load?
A: Yes. The VRLA batteries in the ITA2-80KRT400V37UPRN are hot-swappable and user-replaceable. In a 2+1 parallel bundle, battery maintenance on one unit can be performed while the remaining units maintain the load, eliminating the need for a maintenance downtime window.
Q: What efficiency does this UPS achieve, and does it vary by operating mode?
A: The ITA2-80KRT400V37UPRN achieves greater than 93% efficiency in online double-conversion mode and 99% efficiency in ECO mode. ECO mode reduces heat output and operating costs significantly at 40kW scale, though it involves a brief transfer time on mains fault — a trade-off between efficiency and zero-transfer-time protection.
Q: What is the warranty on the ITA2-80KRT400V37UPRN?
A: The ITA2-80KRT400V37UPRN carries a 2-year limited warranty from Vertiv.
Q: Is this UPS compatible with SNMP-based monitoring platforms?
A: Yes. The bundle includes SNMP management capability, enabling integration with network management systems, BMS platforms, and DCIM tools for remote monitoring of UPS status, battery health, load levels, and alarm conditions.
The ITA2-80KRT400V37UPRN is the configuration I recommend when a customer needs to protect a full rack environment with no tolerance for a single UPS failure. The 2+1 parallel bundle at 40kVA with unity power factor is particularly well-suited to scenarios where every kVA on the nameplate needs to be real usable watts — not a paper number derated to 0.8. That 1.0 power factor is the spec that most buyers overlook until they're mid-sizing and realize they've underprovisioned.
Technical Highlights:
- Unity Power Factor (1.0): 40kVA = 40kW with no derating — eliminates the overprovisioning math that comes with 0.8 PF UPS systems at this capacity class.
- 99% ECO Mode Efficiency: On a 40kW system running continuously, the difference between 93% and 99% efficiency is roughly 2.4kW of heat and power loss recovered — that compounds fast in annual operating costs and HVAC load.
- Hot-Swap VRLA Batteries: User-replaceable without load interruption. In a 2+1 bundle, battery service on one unit while the other two hold load is standard procedure — no maintenance window required.
Deployment Considerations:
- Verify that your facility's three-phase four-wire 400VAC distribution panel can support the full parallel bundle load. Commissioning all three units simultaneously requires careful upstream circuit capacity planning — don't size the feed for a single ITA2 unit.
- ECO mode is compelling on paper at 99% efficiency, but verify with your load profile first. If your connected equipment includes servers with aggressive transient loads, the brief transfer time in ECO mode can cause nuisance trips. Double-conversion mode at >93% is the safer default for mixed server and network gear.
This bundle is the right fit for a mid-density colocation cage, a multi-rack security operations center, or a distributed enterprise equipment room where power continuity is a hard requirement and the facility team needs SNMP visibility into the power layer alongside the rest of the infrastructure stack.
