Vertiv ITA2-15KRT400C 15KVA/KW 3-Phase Rack UPS with Unity Card
Overview
The ITA2-15KRT400C is Vertiv's Liebert ITA2 15KVA/KW three-phase rack-mounted UPS designed for 400/230VAC distribution environments. Targeting data centers, server rooms, and network closets where three-phase power feeds are standard, it delivers unity power factor — meaning every kilovolt-ampere of rated capacity translates directly to usable kilowatts of load support. The included Unity Card adds network management capability out of the box, which matters when you need remote visibility into runtime, load percentage, and alarm states without a separate accessory order.
This unit targets IT infrastructure deployments where single-phase UPS systems simply aren't sized for the job — think high-density compute racks, mid-tier storage arrays, or AV/broadcast equipment rooms fed from three-phase panels. The 400V input/output range (with support for 380V and 415V) covers the international three-phase standard that dominates European and Asia-Pacific data center builds, as well as a growing number of North American facilities migrating to 400V distribution to reduce transmission losses.
Key Features
- 15KVA/KW at Unity Power Factor: A 1.0 power factor rating means the ITA2-15KRT400C supports a full 15kW of real load — not 12kW or 13.5kW as you'd see from legacy 0.8 or 0.9 PF units. For a rack loaded with modern servers drawing 10–14kW, this eliminates the oversizing gymnastics that used to be mandatory with older UPS designs.
- 400/230VAC Three-Phase Output (4W+G Wiring): The four-wire-plus-ground configuration supports both line-to-neutral (230V) and line-to-line (400V) loads simultaneously, which is critical when mixed single-phase and three-phase equipment shares the same UPS. You don't need a separate step-down transformer for single-phase loads on the distribution side.
- Input Voltage Range: 380/400/415VAC: The unit accepts the full spread of international three-phase voltage standards without switching to battery, reducing battery wear in facilities where supply voltage fluctuates between 380V and 415V — common in older building infrastructure or during peak demand periods.
- 93% Efficiency: At 93% efficiency, a fully loaded 15kW unit wastes roughly 1.05kW as heat. Over a year of continuous operation, that's approximately 9,200 kWh saved compared to a comparable 85% efficiency UPS — a real line item on the data center power bill and a reduction in cooling load.
- Scalable Platform (15/20/30/40KVA): The ITA2 product family spans 15 to 40KVA in the same architecture, which matters for phased deployments. If your load grows beyond 15kW, you're not rearchitecting the distribution scheme — you're swapping for a higher-capacity unit in the same family with the same footprint and management interface.
- Unity Card Included: Network management is not an afterthought add-on here. The Unity Card ships with the unit, enabling SNMP monitoring, web-based configuration, and integration with data center infrastructure management (DCIM) platforms. For remote or unmanned facilities, this is the difference between knowing a UPS alarmed and finding out after a load dropped.
- 130mm Form Factor: The compact 130mm depth (likely referring to a specific chassis dimension) makes this suitable for shallow rack enclosures or co-location cages where standard 600mm depth equipment may not fit without tray extensions.
Integration and Compatibility
The ITA2-15KRT400C is designed for rack integration in standard 19-inch enclosures. The 4W+G wiring scheme aligns with IEC and European three-phase distribution standards, and the 380–415V input range covers the majority of international facility power configurations without requiring input transformers. The Unity Card supports SNMP and common DCIM integration paths, making it compatible with most enterprise monitoring platforms. For power protection deployments that require scalability, the broader Vertiv UPS lineup includes higher-capacity ITA2 variants at 20, 30, and 40KVA using the same management ecosystem. If your facility runs a structured network infrastructure with centralized monitoring, the Unity Card's SNMP capability integrates without additional licensing. Buyers sizing battery runtime should consult a UPS selection guide — runtime at 15kW load depends on battery module configuration, which varies by installation.
Frequently Asked Questions
Q: What is the input voltage range of the ITA2-15KRT400C?
A: The ITA2-15KRT400C accepts 380V, 400V, and 415VAC three-phase input, covering the standard international three-phase distribution voltages without requiring input conditioning or transformers.
Q: Does the ITA2-15KRT400C include a network management card?
A: Yes. The Unity Card is included with the ITA2-15KRT400C at no additional cost, enabling SNMP-based remote monitoring, web management, and integration with DCIM platforms out of the box.
Q: What is the power factor of the ITA2-15KRT400C, and why does it matter?
A: The ITA2-15KRT400C operates at unity (1.0) power factor, meaning the full 15KVA rating is available as 15kW of real load capacity. Older UPS units with 0.8 or 0.9 power factor deliver only 12–13.5kW from a 15KVA unit — a significant difference when sizing for modern high-density server loads.
Q: What is the efficiency rating of the ITA2-15KRT400C?
A: The ITA2-15KRT400C is rated at 93% efficiency. At full 15kW load, this means approximately 1.05kW of loss — substantially less heat dissipation and lower operating cost compared to older 85–88% efficient three-phase UPS designs.
Q: Is the ITA2-15KRT400C part of a scalable UPS family?
A: Yes. The Liebert ITA2 family includes 15, 20, 30, and 40KVA models sharing the same architecture and Unity Card management platform. This allows phased capacity upgrades without redesigning distribution infrastructure.
Q: What wiring configuration does the ITA2-15KRT400C use?
A: The ITA2-15KRT400C uses a 4W+G (four-wire plus ground) configuration, supporting both three-phase line-to-line (400V) and single-phase line-to-neutral (230V) loads simultaneously from the same UPS output.
The ITA2-15KRT400C is one of the few rack UPS units at this capacity tier that ships with network management already in the box — the Unity Card isn't an upsell, it's standard. For facilities teams managing remote or unmanned sites, that's a meaningful operational difference. The 93% efficiency rating and unity power factor together mean you're getting 15 real kilowatts of protected capacity with roughly 1kW of heat to manage, which keeps the cooling math simple.
Technical Highlights:
- Unity Power Factor (1.0): The full 15KVA translates to 15kW of usable load capacity — no derating required for modern server equipment that already operates near unity PF itself.
- 93% Efficiency: Reduces wasted energy to approximately 1.05kW at full load, lowering both operating cost and heat output in the rack environment — relevant when cooling is already constrained.
- 380–415VAC Input Range: Handles the full spread of international three-phase voltages without battery transfer, protecting battery cycle life in facilities where incoming voltage varies with load or building age.
Deployment Considerations:
- The 4W+G output supports mixed single-phase and three-phase loads downstream — verify that your PDU or distribution panel is wired to take advantage of both line-to-neutral (230V) and line-to-line (400V) taps before finalizing the distribution layout.
- The 130mm chassis dimension should be verified against your rack enclosure depth before ordering — shallow co-location cages or wall-mount enclosures may require additional clearance planning for cable management at the rear.
The ITA2-15KRT400C is the right call for a European-standard 400V three-phase rack environment where you need genuine 15kW of protected capacity, Unity Card network management from day one, and a clear upgrade path to 20, 30, or 40KVA without changing the distribution architecture.
