Vertiv ITA2-40KRT400V11UN 40kVA/40kW 3-Phase Online UPS with VRLA Battery Bundle
Overview
The Vertiv Liebert ITA2-40KRT400V11UN is a 40kVA/40kW three-phase double-conversion online UPS bundled with two pairs of VRLA batteries — a complete power protection package for data centers, server rooms, and network infrastructure that cannot tolerate voltage sags, surges, or brownouts. Running on 400VAC (240VAC) three-phase four-wire input, the ITA2 continuously conditions output through a true online double-conversion topology, meaning your connected load never draws directly from raw mains power. Every millisecond, the inverter regenerates clean sine-wave AC from the DC bus — any upstream grid event is isolated before it reaches your servers, networking gear, or sensitive electronics.
The rack/tower convertible chassis keeps the footprint compact for both floor-standing and rack-mount deployments, and the included VRLA battery pairs mean you are not sourcing battery cabinets separately. For IT architects and integrators sizing power for critical loads up to 40kVA at 400V, this bundle eliminates a common procurement gap.

Key Features
- 40kVA / 40kW at Unity Power Factor (1.0): A 1.0 power factor means the VA rating equals the watt rating — there is no derating penalty when you connect modern server PSUs, which themselves draw at near-unity PF. You get the full 40kW of usable output without oversizing the UPS to compensate for PF mismatch. This is a meaningful difference over legacy 0.9 PF units, which deliver only 36kW from a 40kVA frame.
- True Online Double-Conversion Technology: Unlike line-interactive or standby designs, double-conversion means zero transfer time on a utility failure — the inverter is already driving the load. For server farms, hyperconverged infrastructure, or network switching cores where even a 4ms gap can trigger reboots or storage I/O errors, this topology is the correct choice. Line-interactive UPS designs are explicitly not appropriate for this class of load.
- 99% Efficiency in Eco Mode (>93% in Double-Conversion Mode): In always-on data center deployments, UPS efficiency directly impacts your annual power bill. At 99% eco-mode efficiency, the ITA2 dissipates minimal heat compared to older online designs, reducing both energy waste and cooling load. The >93% double-conversion efficiency is competitive for this power class and keeps operating costs predictable.
- Hot-Swappable, User-Replaceable VRLA Batteries: Valve-regulated lead-acid batteries can be swapped under load without scheduling a maintenance window or dropping critical systems. For 24/7 environments — colocation facilities, security operation centers, healthcare networks — this eliminates the operational risk of a planned outage just to cycle batteries at end of life.
- Scalable Battery Runtime: The bundle includes two pairs of ITA2 VRLA battery modules, and the platform supports extended runtime through additional battery cabinets. Runtime is engineered to scale with load, allowing power architects to spec the runtime margin that fits the application — short bridge-to-generator for a data center, or extended autonomy for an unmanned remote site.
- SNMP / Unity Card Network Management: The included Unity Card enables SNMP-based monitoring, so the UPS integrates directly into existing network management platforms and DCIM tools. Remote visibility into battery health, load percentage, input/output voltage, and alarm states eliminates the need for physical inspection rounds and supports proactive maintenance before a failure event.
- ENERGY STAR 2.0 Certified: Energy Star 2.0 qualification confirms independently verified efficiency performance — relevant for enterprise sustainability reporting, green building certifications, and data center energy compliance programs.
- Rack/Tower Convertible Form Factor: Deploy in a standard 19-inch equipment rack or floor-stand as a tower — the same chassis handles both orientations. This flexibility matters in edge deployments where rack space is constrained or where the UPS may need to be repositioned as the installation evolves.
Integration and Compatibility
The ITA2-40KRT400V11UN is designed to protect microcomputers, servers, networking equipment, and other sensitive electronics operating on three-phase 400VAC (with 240VAC compatibility) infrastructure. The Unity Card enables SNMP integration with standard network management systems and supports optional software monitoring for both manned and unmanned facilities. The optional maintenance bypass cabinet — not included in this bundle but available as an add-on — allows the UPS to be serviced without interrupting the connected load, a critical operational requirement for any system supporting always-on infrastructure.
For security integrators deploying this unit as backbone power for IP camera systems, NVRs, or access control infrastructure, the 40kW capacity at unity power factor handles high-channel-count NVR arrays and PoE switch banks. Pair with a managed PoE switch downstream for a fully protected edge network stack. See the UPS and power protection category for runtime extension cabinets and compatible accessories.
Frequently Asked Questions
Q: What is included in the ITA2-40KRT400V11UN bundle?
A: The bundle includes the Vertiv Liebert ITA2 40kVA/40kW 400VAC three-phase UPS with Unity Card (SNMP) and two pairs of ITA2 VRLA battery modules.
Q: What is the warranty on the ITA2-40KRT400V11UN?
A: The ITA2-40KRT400V11UN carries a 2-year manufacturer warranty.
Q: Does the ITA2-40KRT400V11UN support SNMP monitoring?
A: Yes. The Unity Card included in this bundle provides SNMP network management capability, enabling remote monitoring of load, battery status, voltage, and alarms through compatible NMS or DCIM platforms.
Q: What is the difference between double-conversion mode and eco mode on this UPS?
A: In double-conversion mode, the load is continuously powered by the inverter with full isolation from the utility — maximum protection, efficiency above 93%. In eco mode, the load is served more directly from conditioned utility power when conditions are stable, reaching 99% efficiency. Eco mode reduces energy consumption but offers slightly less isolation. The correct mode depends on load sensitivity and site power quality.
Q: Can the ITA2-40KRT400V11UN be rack-mounted?
A: Yes. The chassis is rack/tower convertible and installs in a standard 19-inch equipment rack or operates as a floor-standing tower unit.
Q: Are the batteries in the ITA2-40KRT400V11UN hot-swappable?
A: Yes. The VRLA battery modules are hot-swappable and user-replaceable, meaning battery replacement can be performed without shutting down the connected load or scheduling a maintenance outage.
The spec that stands out immediately on the ITA2-40KRT400V11UN is the unity power factor — 1.0 PF at 40kVA means you are delivering a full 40kW to the load with no derating. In practice, this changes the sizing math significantly compared to a 0.9 PF frame, where you would need a 44kVA unit to hit the same usable wattage. For integrators building out a data hall or a large security operations center, that distinction affects both equipment cost and physical footprint.
Technical Highlights:
- 40kVA / 40kW at 1.0 Power Factor: Full rated wattage delivered without PF derating — eliminates the oversizing margin required with legacy 0.9 PF frames on modern server infrastructure.
- Double-Conversion Topology with Zero Transfer Time: The inverter continuously drives the load; a utility failure produces no gap in output power. This is the only topology appropriate for storage arrays, HCI clusters, or network cores where a 4ms transfer can cause I/O faults or NIC resets.
- 99% Eco-Mode / >93% Double-Conversion Efficiency: At 40kW continuous, the difference between 93% and 99% efficiency translates to roughly 2.4kW less heat dissipation in eco mode — a real cooling load reduction in a sealed rack environment or a constrained edge room.
Deployment Considerations:
- The bundle ships with two pairs of VRLA battery modules, but runtime at full 40kW load will be limited — if the application requires more than a few minutes of backup, plan the battery extension cabinet configuration before installation, not after.
- The optional maintenance bypass cabinet is not included in this SKU. For any deployment where the UPS must be serviced without dropping the load — data centers, 24/7 security infrastructure — specify the bypass cabinet as a separate line item in the BOM.
This unit is well-positioned for enterprise security operations centers running high-channel NVR stacks, PoE switch banks, and workstation clusters on three-phase 400V infrastructure — anywhere a single-phase UPS topology is undersized and runtime extensibility needs to be engineered into the design from day one.
