Vertiv ITA2-30KRT208V31UPN 15kVA 3-Phase Online Double-Conversion UPS
Overview
The Vertiv Liebert ITA2-30KRT208V31UPN is a 15kVA/15kW three-phase online double-conversion UPS configured in a 2+0 parallel bundle for 208/120VAC (220/127VAC) environments. Rack/tower convertible and designed for edge data rooms, server closets, and distributed IT infrastructure, this unit continuously conditions and regulates output voltage — meaning connected equipment never touches raw utility power, even during sags, swells, or switchover events. If you're protecting servers, networking gear, or other load-sensitive equipment in a three-phase environment and need a compact, scalable power path, the ITA2-30KRT208V31UPN is worth a close look.
The 2+0 parallel configuration delivers up to 30kVA of combined capacity from two coordinated units, giving you capacity headroom today and a clear upgrade path tomorrow without adding a separate parallel frame or bypass cabinet.
Key Features
- Online Double-Conversion Technology: Unlike line-interactive UPS designs that switch to battery only on failure, online double-conversion means the inverter is always carrying the load. Utility power feeds through AC-DC-AC conversion continuously, so connected equipment receives pure sine wave output regardless of what's happening on the input side — critical for servers and networking hardware with sensitive power supplies.
- Unity Power Factor (1.0): A 1.0 power factor means the kVA and kW ratings are identical — 15kVA equals 15kW of real load capacity. Many competing UPS units derate to 0.8 or 0.9 power factor, meaning a nominally 15kVA unit only delivers 12–13.5kW of usable capacity. Here, every watt of rated capacity is available for your load.
- 99% Efficiency in ECO Mode: Running at 99% efficiency in ECO mode means minimal heat generation and dramatically lower operating costs at scale. Even in standard double-conversion mode, efficiency exceeds 93%. For a UPS running 24/7, the difference between 93% and 99% efficiency adds up to real dollars on your energy bill over a three-to-five year deployment cycle.
- 2+0 Parallel Capacity Scaling: The parallel architecture allows two ITA2 units to operate together, delivering up to 30kVA on a single power path. This is a capacity play, not a redundancy play — 2+0 means both units are active under load simultaneously rather than one sitting idle as a hot spare. Plan your load distribution accordingly.
- Hot-Swappable, User-Replaceable VRLA Batteries: Valve-regulated lead acid batteries can be swapped without shutting down the load, which matters in environments where scheduled downtime windows are tight or non-existent. The four-pair VRLA battery configuration included in this bundle gives you on-site spares ready to go.
- Scalable Battery Runtime: Runtime is not fixed — additional external battery modules can extend backup time beyond what the internal VRLA packs provide. This is relevant if your recovery time objective (RTO) requires more than a few minutes of bridge power during extended outages.
- Intelligent Card Slot with SNMP / Network Interface Card Support: The included Unity Card enables SNMP-based monitoring and integration with network management platforms. This means your UPS status — load percentage, battery health, runtime remaining, input voltage — is visible alongside switches and servers in your NMS or DCIM tool, not just on the front panel.
- ENERGY STAR 2.0 Certified: ENERGY STAR 2.0 certification validates the efficiency claims independently. For facilities teams managing energy budgets or sustainability targets, this certification supports procurement justification and may qualify for utility rebate programs depending on your region.
- Rack/Tower Convertible Form Factor: Deploy in a standard 19-inch rack or convert to tower orientation without additional hardware. This flexibility matters in mixed environments — edge closets without full racks, or server rooms where floor space and rack space are both constrained.
Integration & Compatibility
The ITA2-30KRT208V31UPN connects into three-phase 208/120VAC infrastructure (with support for 220/127VAC configurations), making it compatible with standard North American commercial electrical systems. The Unity Card included in this bundle provides out-of-box network management via SNMP, enabling integration with most enterprise NMS platforms and DCIM solutions without additional licensing. For sites running UPS and power protection alongside distributed IT infrastructure, the intelligent card slot means you can monitor this unit alongside switches, servers, and access points in a unified dashboard. The optional maintenance bypass cabinet — referenced in Vertiv's documentation for this family — supports enhanced availability during planned service without dropping the load, though that component is ordered separately. Review your facility's input wiring configuration and confirm compatibility with your electrical panel's three-phase output before installation; the 2+0 parallel wiring requires careful load balancing between both units to avoid asymmetric loading conditions that could trigger overload alarms on one unit while the other runs underloaded.
Frequently Asked Questions
Q: What is the difference between the 2+0 parallel configuration and a redundant (N+1) setup?
A: The 2+0 configuration in the ITA2-30KRT208V31UPN is a capacity configuration — both units share the load simultaneously to deliver up to 30kVA combined. In an N+1 redundant setup, one unit would be a dedicated spare. With 2+0, if one unit fails, the remaining unit must carry the full load, so your load planning should account for that scenario.
Q: What battery type is included and can batteries be replaced without shutting down?
A: The bundle includes four pairs of valve-regulated lead acid (VRLA) batteries. Yes, batteries are hot-swappable and user-replaceable, allowing field replacement without powering down connected equipment.
Q: What is the warranty on the ITA2-30KRT208V31UPN?
A: The ITA2-30KRT208V31UPN carries a 2-year manufacturer warranty.
Q: Does the ITA2-30KRT208V31UPN include network management capability out of the box?
A: Yes. The bundle includes a Unity Card that provides SNMP-based network management and integrates with standard NMS platforms, so UPS status monitoring is available immediately without purchasing a separate network interface card.
Q: Is the ITA2-30KRT208V31UPN ENERGY STAR certified?
A: Yes, the ITA2-30KRT208V31UPN carries ENERGY STAR 2.0 certification, validating its efficiency performance independently of manufacturer claims.
Q: What input voltage does the ITA2-30KRT208V31UPN require?
A: The unit accepts 208/120VAC input (with support for 220/127VAC), three-phase, four-wire. Confirm your facility's electrical panel output matches these specifications before installation.
The spec I keep coming back to on the ITA2-30KRT208V31UPN is the unity power factor — 1.0, not the 0.8 or 0.9 you see on a lot of three-phase units in this class. That single number means you get 15kW of actual load capacity from a 15kVA rated unit, with nothing held back by a derating factor. When you're sizing power protection for a dense server rack or a loaded network closet, that gap matters more than most people realize until they've burned headroom on a derated unit mid-deployment.
Technical Highlights:
- Unity Power Factor (1.0): Full 15kW available from a 15kVA rating — no derating. Most competing three-phase units derate to 0.8, delivering only 12kW from a nominally equal rating.
- Dual Efficiency Modes: Over 93% in online double-conversion mode; 99% in ECO mode. For a 15kW load running 8,760 hours per year, the ECO mode efficiency difference translates to measurable reduction in heat load and energy spend.
- Hot-Swap VRLA Batteries: Four pairs of valve-regulated batteries are user-replaceable under load. No maintenance window required for battery service — the load stays live throughout the swap.
Deployment Considerations:
- The 2+0 parallel configuration is a capacity architecture, not a redundancy architecture. If one unit goes offline, the surviving unit must carry the full combined load — plan your load budgets to ensure one unit can handle a worst-case scenario before you need it to.
- Input wiring for parallel operation requires careful load balancing between both units at the electrical panel. Asymmetric loading can trigger overload conditions on the more heavily loaded unit even when aggregate load is within spec. Confirm wiring with a licensed electrician familiar with three-phase parallel UPS installations.
This bundle is well-matched for distributed enterprise edge deployments — branch office server closets, campus IDF rooms, or retail back-of-house IT rooms running 208V three-phase infrastructure where a rack-convertible form factor and on-board SNMP management eliminate the need for a separate monitoring appliance.
