Vertiv ITA2-80KRT400V31UPN 40kVA 400V 3-Phase Online Double-Conversion Rack/Tower UPS
Overview
The Vertiv Liebert ITA2-80KRT400V31UPN is a 40kVA/40kW, three-phase, online double-conversion UPS configured in a 2+0 parallel architecture for up to 80kVA of expandable capacity. Built around the Liebert ITA2 platform, this bundle pairs the UPS with a Unity Card, SNMP network management, and four pairs of VRLA batteries — everything needed to deliver clean, regulated sine wave power to servers, networking gear, and other critical infrastructure in a single rack-ready package.
Double-conversion technology means incoming AC is continuously rectified to DC and then re-inverted to AC on the output side. The load never runs directly off raw utility power — every volt delivered to your equipment has been conditioned and regulated. For facilities where utility quality is inconsistent or where even sub-cycle transients are unacceptable, that continuous conditioning is the operative difference between this architecture and line-interactive or standby designs.
Key Features
- 40kVA / 40kW at Unity Power Factor (1.0): A unity power factor means there is no gap between kVA and kW ratings — 40kVA delivers 40kW of real power to the load. Older UPS designs with 0.8 PF force you to oversize: a 50kVA unit to get 40kW. Here, the nameplate is what you get, which simplifies capacity planning and reduces the capital cost of over-provisioning.
- 2+0 Parallel Architecture (scalable to 80kVA): Two ITA2 units operating in parallel double available capacity to 80kVA 400V without adding a separate distribution layer. For data centers or comms rooms expecting phased load growth, this means you can start with one module and add the second when the load justifies it — without replacing infrastructure.
- 99% Efficiency in Eco Mode: In double-conversion mode efficiency exceeds 93%, which is respectable for a true online UPS. In eco mode the unit reaches 99% — meaningful at 40kW scale, where even a few percentage points of efficiency gap translates to hundreds of watts of continuous heat load and measurable energy cost over a year of 24/7 operation.
- 400VAC (240VAC) Three-Phase, 4-Wire Input: Designed for European and international three-phase distribution. The 400VAC input with 240VAC phase-to-neutral accommodates standard 3-phase 4-wire infrastructure common in commercial and industrial facilities outside North America, eliminating step-down transformer requirements in those environments.
- Hot-Swappable, User-Replaceable VRLA Batteries: The four pairs of valve-regulated lead-acid batteries can be swapped under load without scheduling downtime. In a 24/7 operations environment, battery maintenance has historically been a forced outage event — hot-swap capability eliminates that window. VRLA chemistry also means no liquid electrolyte topping or venting concerns in enclosed rack spaces.
- ENERGY STAR 2.0 Certification: ENERGY STAR 2.0 qualification matters in procurement contexts where government or enterprise sustainability requirements gate purchasing decisions. It also provides independent third-party validation of the efficiency claims — not just a vendor spec.
- Intelligent Card Slot with Unity Card and SNMP: The included Unity Card exposes the UPS over SNMP, enabling integration with existing NMS platforms, DCIM tools, or scripted monitoring. You get real-time load, battery health, runtime estimates, and alarm forwarding without purchasing a separate management card — it ships in the bundle.
- Rack/Tower Convertible Form Factor: The ITA2 chassis converts between rack-mount and tower orientations, which matters during initial deployment when the final rack environment may not yet be built out, or in branch/edge locations where a dedicated rack isn't available.
- Pure Sine Wave Output: Active PFC power supplies — standard in modern servers — require true sine wave input to operate correctly. A modified sine wave or stepped approximation causes instability or premature component failure in those loads. The ITA2-80KRT400V31UPN delivers a true sine wave output at all times, including during battery operation.
- 2-Year Manufacturer Warranty: The unit ships with a 2-year warranty covering defects in materials and workmanship — confirm coverage terms with documentation included at time of purchase.
Integration and Compatibility
The ITA2-80KRT400V31UPN (often searched as ITA2 80KRT400V31UPN) integrates with standard three-phase distribution infrastructure. The SNMP-capable Unity Card enables connectivity with network management systems that support SNMPv1/v2c/v3 polling and trap reception. The optional maintenance bypass cabinet, referenced in the product series documentation, supports enhanced availability scenarios where the UPS itself requires service without dropping the protected load — confirm compatibility with the specific bypass accessory SKU before ordering.
Battery runtime is scalable through the Liebert ITA2 platform's external battery cabinet options, though the baseline VRLA battery complement included in this bundle provides initial runtime appropriate for orderly shutdown of connected systems. Actual runtime varies with load — plan for runtime at 50–75% of rated load, which is where most production server environments operate.
For the UPS and power protection category, the ITA2 sits in the three-phase online segment. Pair it with a compatible maintenance bypass switch and Vertiv power infrastructure accessories for a complete critical power solution. If your environment uses a managed network switch infrastructure, the SNMP card enables automated graceful shutdown scripting coordinated with your NMS.
Frequently Asked Questions
Q: What is the actual load capacity of the ITA2-80KRT400V31UPN?

Q: Does the ITA2-80KRT400V31UPN include network management capabilities?
A: Yes. The bundle includes a Unity Card with SNMP and network interface card functionality. This enables integration with SNMP-based NMS platforms for remote monitoring of load, battery status, runtime, and alarm conditions.
Q: What battery type is included and can they be replaced under load?
A: The bundle includes four pairs of valve-regulated lead-acid (VRLA) batteries. The ITA2 platform supports hot-swappable, user-replaceable batteries, meaning battery maintenance can be performed without taking the protected load offline.
Q: What is the input voltage requirement for this UPS?
A: The ITA2-80KRT400V31UPN requires 400VAC (240VAC phase-to-neutral) three-phase, 4-wire input — standard for commercial and industrial three-phase distribution in European and international facilities.

When I look at the ITA2-80KRT400V31UPN, the spec that anchors the deployment decision is the unity power factor — 40kVA is 40kW, full stop. That eliminates the over-sizing math that plagues procurement when spec sheets show 0.8 PF designs, and it means you are buying exactly the capacity you need for a 40kW three-phase load without padding the order by 25%.
Technical Highlights:
- Double-Conversion Online Architecture: The load is always running off inverted DC — not raw utility. Sub-cycle sags, swells, and frequency deviations that would pass through a line-interactive design are blocked entirely. For server infrastructure with active-PFC supplies, this is the correct protection class.
- 99% Eco-Mode Efficiency: At 40kW continuous, the difference between 93% and 99% efficiency is roughly 2.6kW of heat — that is meaningful in a rack environment where every watt of heat load costs cooling capacity. Eco mode is a viable operating point in stable utility environments where brief transfer to bypass during transients is acceptable.
- SNMP Unity Card Included: The management card ships in the bundle, not as an add-on line item. In practice this means day-one SNMP visibility into load percentage, estimated runtime, battery health, and alarm traps — no separate procurement cycle for the card.
Deployment Considerations:
- The 400VAC three-phase 4-wire input requirement is correct for international and European commercial distribution but will require a step-up or different model selection for North American 208V three-phase environments — confirm your facility's distribution voltage before ordering.
- Battery runtime at full 40kW load will be limited with the four included VRLA pairs; plan for orderly shutdown runtime rather than extended ride-through. If extended runtime is a hard requirement, spec external battery cabinet options from the ITA2 platform accessory lineup before finalizing the order.
The ITA2-80KRT400V31UPN is the right call for a European or international data hall or comms room running 400V three-phase distribution at loads between 20–40kW today, with a credible path to 80kVA as the environment grows — the 2+0 parallel architecture means that capacity expansion is additive, not a forklift.
