Vertiv ITA2-15KRT208V31URN 15kVA/15kW 1+1 Redundant Online Double-Conversion UPS
Overview
The Vertiv Liebert ITA2-15KRT208V31URN is a 15kVA/15kW three-phase online double-conversion UPS bundle built for IT infrastructure that cannot tolerate a momentary gap in clean power — servers, networking stacks, edge compute, and storage arrays running on 208/120VAC (or 220/127VAC) three-phase circuits. This rack/tower-convertible unit ships with four pairs of VRLA batteries and a Unity Card for SNMP management, giving you a fully integrated 1+1 redundant power platform in a single bundle rather than a collection of separately sourced components.
Unlike line-interactive or standby designs, double-conversion topology means the load is always running from the inverter — grid anomalies, sags, swells, and transients never reach your equipment. The ITA2's high-frequency architecture keeps the footprint compact relative to its 15kW capacity, which matters in dense rack environments where every rack unit has a cost.
Key Features
- Online Double-Conversion Technology: The load runs continuously from the conditioned inverter output — not the raw utility feed. Every voltage sag, harmonic distortion event, or brief outage is absorbed invisibly. For server rooms or edge deployments where even a 10ms transfer time from a line-interactive UPS would trigger a server reboot, this is the topology you need.
- 1+1 Redundancy: Two UPS modules operating in parallel with one-to-one redundancy means either module can carry the full 15kW load independently. If one module faults, the other assumes the load without any interruption. Redundancy at the UPS level eliminates a single point of failure that dual-corded servers and PDUs alone cannot address.
- Unity Power Factor (1.0): The ITA2 delivers a true 1:1 relationship between VA and watts — 15kVA equals 15kW of usable real power. Many competing platforms at this capacity derate to 0.9 power factor, yielding only 13.5kW of real power. That difference funds additional servers or storage on the same UPS circuit.
- 99% Efficiency in Eco Mode / >93% in Double-Conversion: Running at 99% efficiency in eco mode dramatically reduces heat output and operating costs. At 15kW continuous load, the difference between 93% and 99% efficiency is roughly 900W of heat you are not dumping into your cooling system — a real factor in room cooling budget and annual electricity cost.
- Hot-Swappable, User-Replaceable VRLA Batteries: The four included VRLA battery pairs can be swapped under load without powering down protected equipment. For 24/7 operations, this eliminates the planned downtime window that non-hot-swap battery replacement would otherwise require. VRLA (valve-regulated lead acid) chemistry is maintenance-free under normal operating conditions.
- Scalable Battery Runtime: The ITA2 architecture supports extended battery modules, allowing runtime to be extended beyond the baseline provided by the included four VRLA pairs. Size runtime to your specific recovery time objective without replacing the UPS itself.
- SNMP Network Management via Unity Card: The included Unity Card provides SNMP-based remote monitoring and control — integrate UPS status directly into your NMS, receive proactive alerts on battery health, input voltage anomalies, and load levels without requiring a separate management appliance.
- ENERGY STAR 2.0 Certified: ENERGY STAR 2.0 certification validates the efficiency claims under standardized test conditions — relevant for data center operators tracking PUE or facilities teams managing energy compliance requirements.
- Rack/Tower Convertible Form Factor: Deploy in an open-frame or enclosed rack without dedicated UPS rack space — or stand it vertically in a wiring closet or edge location. The same hardware adapts to both deployment contexts without additional hardware kits.
- Output Distribution Options: The ITA2 platform supports configurable output distribution, allowing you to match outlet types and circuit protection to the specific load mix — useful when the protected equipment includes a combination of standard IEC C13 and higher-draw C19 loads.
Integration and Compatibility
The ITA2-15KRT208V31URN (often searched as ITA2 15KRT208V31URN) is designed for three-phase 208/120VAC input environments — confirm your facility delivers three-phase power before specifying this unit. Single-phase facilities require a different platform. The 220/127VAC input rating extends applicability to international installations where three-phase 220V distribution is standard.
SNMP integration via the bundled Unity Card is compatible with standard NMS platforms supporting SNMP v1/v2c/v3 traps, including SolarWinds, PRTG, Nagios, and similar enterprise monitoring environments. For deeper integration with Vertiv's management ecosystem, the Unity Card supports connection to Vertiv's Liebert SiteScan or third-party DCIM platforms via standard protocols.
The optional maintenance bypass cabinet — referenced in the product specification — is a separate accessory that allows the UPS to be fully isolated for service while the load continues to receive utility power. For environments with SLA obligations that prohibit any power interruption, factor the bypass cabinet into the installation budget from the outset.

If you are deploying this UPS in a security or surveillance infrastructure rack, pair it with managed PoE switches and review NVR storage platforms that benefit from the clean power this unit delivers.
Frequently Asked Questions
Q: What is the difference between the 1+1 redundancy on the ITA2-15KRT208V31URN and a standard non-redundant UPS?
A: In a 1+1 configuration, two UPS modules operate in parallel — each capable of supporting the full 15kW load independently. If one module experiences a fault, the second immediately carries the entire load with no transfer gap. A standard single-module UPS has no such failover; a module failure means the load drops to battery or loses protection entirely.
Q: Does the ITA2-15KRT208V31URN require three-phase input power?
A: Yes. The ITA2-15KRT208V31URN is designed for three-phase 208/120VAC (or 220/127VAC) input. Single-phase facilities cannot power this unit. Verify your facility's electrical service before specifying this model.
Q: Can the batteries be replaced without shutting down the protected equipment?
A: Yes. The ITA2 features hot-swappable, user-replaceable VRLA batteries. Battery replacement can be performed under load, eliminating the planned downtime window that would otherwise be required.
Q: What is the warranty on the ITA2-15KRT208V31URN?
A: The ITA2-15KRT208V31URN carries a 2-year manufacturer warranty.
Q: Is the SNMP management card included, or is it a separate purchase?
A: The Unity Card for SNMP management is included in the ITA2-15KRT208V31URN bundle. No separate management card purchase is required for basic SNMP integration.
Q: What does the 99% efficiency rating mean in practice?
A: The 99% efficiency figure applies to eco mode operation. In eco mode, the unit passes power through with minimal conversion losses while remaining ready to switch to double-conversion on demand. At 15kW load, the roughly 6% efficiency gain over standard double-conversion mode (~93%) equates to approximately 900W less heat dissipated — reducing both cooling load and annual electricity cost.
The ITA2-15KRT208V31URN is the bundle I recommend when an integrator or IT architect needs 15kW of three-phase double-conversion protection and does not want to piece together the redundancy story after the fact. The 1+1 parallel architecture ships ready to commission — both modules, four pairs of VRLA batteries, and the Unity Card for SNMP are in the box. No separate redundancy module to spec, no management card to source separately.
Technical Highlights:
- Unity Power Factor (1.0): At 15kVA with a 1.0 power factor, you get the full 15kW of real power — not the 13.5kW a 0.9-PF competitor delivers. That 1.5kW difference is two or three additional 1U servers you can protect on the same circuit without upsizing.
- 99% Eco-Mode Efficiency: Roughly 900W less heat at full load compared to a 93%-efficient double-conversion competitor. Over a three-year cycle that is meaningful in both cooling capacity headroom and utility spend — especially in edge or branch deployments where cooling is undersized relative to the load.
- Hot-Swap VRLA Batteries: Four battery pairs, all field-replaceable under load. In a 24/7 security operations center or surveillance head-end, planned battery replacement without a maintenance window is not a luxury — it is a basic operational requirement.
Deployment Considerations:
- Three-phase 208/120VAC input is non-negotiable for this model — confirm your panel and feed before the unit ships. A single-phase site requires a completely different UPS platform; there is no adapter path.
- The optional maintenance bypass cabinet is not included and should be budgeted separately for any deployment where the UPS itself needs to come offline for service while the load stays live on utility power. Do not assume bypass capability is built in.
The ITA2-15KRT208V31URN is the right specification for a security operations center head-end, a mid-size data closet running a surveillance NVR stack plus core switching, or an edge compute node where three-phase power is available and a single UPS fault cannot be an event. The 1+1 architecture handles that constraint cleanly without requiring a separate bypass transfer switch in the primary failure scenario.
