Vertiv ITA2-30KRT208V37UPRN 15kVA 3-Phase Online Double-Conversion UPS Bundle
Overview
The Vertiv Liebert ITA2-30KRT208V37UPRN is a 15kVA/15kW three-phase, rack/tower-convertible, online double-conversion UPS configured in a 2+1 redundant parallel bundle. It is built to deliver clean, conditioned sine-wave power to servers, networking infrastructure, and other sensitive equipment on 208/120VAC (or 220/127VAC) three-phase four-wire circuits. If your environment cannot tolerate a single UPS failure taking down a critical load, the 2+1 architecture is the core reason to specify this bundle over a standalone unit — one module can fail or go offline for service while the remaining two continue to carry the full 15kW load without interruption.
The ITA2 platform uses true online double-conversion technology, meaning input power is continuously rectified to DC and then re-inverted to AC output. Every volt delivered to your equipment is regenerated from scratch — there is no transfer time to battery on a power event, and input transients, frequency drift, and voltage sags are fully isolated from the load. For three-phase UPS systems protecting edge data rooms, mid-size server rooms, or distributed IT closets, this translates directly to zero-disturbance runtime during grid anomalies.
Key Features
- 2+1 Redundant Parallel Architecture: The bundle ships pre-configured for N+1 redundancy at 15kVA/15kW. If one module fails, the other two carry the load without any switchover event — critical in environments where a momentary gap is unacceptable, such as financial trading infrastructure or healthcare imaging systems.
- Online Double-Conversion Technology: Input power is rectified and re-inverted 100% of the time. There is no transfer delay when utility power degrades — the load never sees the disturbance. This is the correct topology for sensitive electronics that cannot tolerate even a 4ms transfer gap that static-switch or line-interactive designs allow.
- Unity Power Factor (1.0): A 1.0 power factor means the full 15kVA rating is available as usable watts — 15kW. Many UPS units with a 0.8 or 0.9 PF deliver only 12kW or 13.5kW from the same VA rating. Specify load budgets in actual watts and this UPS delivers them without derating.
- High Operating Efficiency — 99% Eco Mode / >93% Double Conversion: In eco mode, the ITA2 achieves 99% efficiency, materially reducing heat output and operating cost in always-on installations. In full double-conversion mode, efficiency exceeds 93% — above the threshold where heat dissipation becomes a significant data-room cooling burden. For a 15kW load running 8,760 hours per year, the difference between 93% and 88% efficiency is real money on the power bill.
- ENERGY STAR 2.0 Certified: Verifiable third-party efficiency certification — relevant if your facility has sustainability reporting requirements or you are targeting LEED points on the electrical infrastructure side.
- Hot-Swappable, User-Replaceable VRLA Batteries: Valve-regulated lead-acid batteries can be swapped without taking the load offline. In a 24/7 environment, planned battery replacement no longer requires a maintenance window or a generator. The VRLA chemistry is sealed, non-spillable, and does not require watering — lower ongoing maintenance burden than flooded-cell alternatives.
- Scalable Battery Runtime: The bundle supports extended runtime via additional battery cabinets, letting you match autonomy to actual load and criticality rather than accepting a fixed runtime that either over-provisions or under-protects.
- SNMP Network Management: Built-in SNMP enables integration with existing network management platforms and data center infrastructure management (DCIM) tools. You can monitor load percentage, battery state, runtime remaining, and alarm conditions remotely — no local access required for day-to-day oversight.
- Rack/Tower Convertible Form Factor: Installs in a standard equipment rack or stands alone as a tower — useful when the deployment site has not finalized its rack strategy or when a small server room does not justify a full rack enclosure.
- Intuitive Control Panel: Local display provides direct access to load, battery, and alarm status without requiring a laptop or network connection — faster triage during an incident.
Integration & Compatibility
The ITA2-30KRT208V37UPRN operates on 208/120VAC or 220/127VAC three-phase four-wire input, making it compatible with standard North American three-phase electrical service as well as international 220V three-phase environments. SNMP support enables integration with network management and monitoring platforms that support standard MIBs. The optional maintenance bypass cabinet — referenced in the Vertiv product line — allows the UPS to be serviced or replaced while the load remains energized, a prerequisite for any environment with a no-downtime SLA. Battery runtime is scalable, so this bundle can be paired with additional UPS battery cabinets to extend autonomy beyond the base configuration. The unity power factor output is compatible with modern server PSUs and high-efficiency networking equipment that present near-unity loads, avoiding the reactive power mismatch issues that arise when pairing legacy 0.8 PF UPS units with modern 0.9–1.0 PF IT loads.
For larger three-phase power protection deployments, review the broader Vertiv power protection line including higher-capacity Liebert systems for enterprise data center applications.
Frequently Asked Questions
Q: What does the 2+1 configuration mean for the ITA2-30KRT208V37UPRN, and how does redundancy work?
A: The 2+1 configuration means two UPS modules share the load in parallel while a third stands ready as a redundant unit. If any single module fails or is taken offline for maintenance, the remaining two continue to supply the full 15kVA/15kW load without interruption or switchover delay. This is N+1 redundancy — one module of failure tolerance at full rated capacity.
Q: What is the difference between 99% eco-mode efficiency and the >93% double-conversion efficiency?
A: In eco mode, the ITA2 passes utility power through with minimal conditioning, achieving 99% efficiency — lowest possible heat and operating cost, but with a brief transfer time if utility power fails. In full double-conversion mode (>93% efficiency), all output power is continuously regenerated from DC, providing zero-transfer-time protection. The correct mode depends on your tolerance for the small eco-mode transfer gap versus your electricity cost and cooling budget.
Q: What battery type does the ITA2-30KRT208V37UPRN use, and can batteries be replaced without downtime?
A: The ITA2-30KRT208V37UPRN uses valve-regulated lead-acid (VRLA) batteries. These are sealed, maintenance-free, and hot-swappable — meaning you can replace batteries while the UPS remains online and the load stays energized, with no maintenance window required.
Q: What warranty does the ITA2-30KRT208V37UPRN carry?
A: The ITA2-30KRT208V37UPRN includes a 2-year manufacturer warranty.
Q: Does the ITA2-30KRT208V37UPRN support remote monitoring?
A: Yes. The bundle includes SNMP network management capability, enabling integration with standard network monitoring and DCIM platforms for remote visibility into load, battery status, runtime, and alarms.
Q: What input power does the ITA2-30KRT208V37UPRN require?
A: The ITA2-30KRT208V37UPRN requires three-phase four-wire input at 208/120VAC (or 220/127VAC). It is not compatible with single-phase electrical service. Confirm your facility has appropriately rated three-phase circuits and breaker capacity before installation.
The ITA2-30KRT208V37UPRN is the bundle I recommend when a customer has a hard no-single-point-of-failure requirement and a 15kW three-phase load — the 2+1 parallel redundant configuration means you get N+1 protection at full capacity, and with hot-swap VRLA batteries, you can schedule routine battery maintenance without coordinating a downtime window. The unity power factor (1.0) is a quiet but important spec: at 15kVA, you actually get 15kW of usable output, not 12kW like you would from a legacy 0.8 PF unit of the same VA rating.
Technical Highlights:
- 2+1 Redundant Parallel at 15kVA/15kW: Full load capacity is maintained even with one module offline — this is the topology for environments where a UPS failure cannot be allowed to cascade into a load outage.
- 99% Eco-Mode / >93% Double-Conversion Efficiency: In double-conversion mode, losses stay under 7% of 15kW — roughly 1,050W of heat to manage in the room. Eco mode cuts that further but introduces a small transfer gap; size your cooling and make the mode decision deliberately.
- ENERGY STAR 2.0 + SNMP: Third-party efficiency certification supports sustainability reporting, and native SNMP means this integrates directly into existing monitoring stacks without a proprietary management card add-on.
Deployment Considerations:
- Three-phase four-wire input at 208/120VAC is a hard requirement — verify your facility's electrical panel and confirm breaker sizing before ordering. This is not a unit you can adapt to single-phase service.
- The optional maintenance bypass cabinet is worth specifying at procurement if your SLA prohibits any load interruption during UPS servicing — retrofitting it later adds cost and scheduling complexity.
The ITA2-30KRT208V37UPRN is the right specification for mid-size server rooms, edge data centers, and distributed IT closets where three-phase power is available and N+1 redundancy is a written requirement — healthcare facilities, financial branch infrastructure, and manufacturing control rooms with 24/7 uptime obligations are the scenarios where this bundle earns its place over a single higher-capacity unit.
