Vertiv ITA2-20KRT400C 20KVA 3-Phase Rack-Mount UPS with Unity Management Card
Overview
The Vertiv Liebert ITA2-20KRT400C is a 20KVA/20KW 3-phase online double-conversion UPS designed for rack-mount deployment in data centers, server rooms, and critical infrastructure environments running 400/230VAC three-phase power. At unity power factor, every KVA translates directly to usable kilowatts — so the 20KVA rating here isn't a paper spec that shrinks to 16KW under real load. That matters when you're protecting dense compute or storage racks where power draw is predictable and margins are tight.
The ITA2-20KRT400C ships with the Vertiv Unity Card included, giving you network-based management and monitoring without sourcing a separate card after the fact. If you're evaluating the broader Vertiv power protection lineup, this model sits in the mid-range of the ITA2 family alongside 5KVA and 8/10/15KVA variants — useful context when sizing across a mixed environment.
Key Features
- 20KVA/KW at Unity Power Factor: A 1.0 power factor means rated KVA equals actual KW output — no derating math required when planning circuit capacity. Size your PDU and breaker to 20KW and you're done.
- Online Double-Conversion Topology: Incoming AC is continuously converted to DC and back to clean AC, so connected equipment sees synthesized power regardless of input quality. Sags, swells, surges, and frequency deviations on the utility feed don't reach your load — critical in facilities with variable grid quality or generator-backed power.
- 400/230VAC Three-Phase Input and Output: Sized for European and international three-phase infrastructure. If your facility runs 400V three-phase distribution — common in EU data centers and industrial environments — this unit integrates directly without step-down transformers.
- Unity Card Included: Network management is built into the purchase. The Unity Card enables SNMP, web-based monitoring, email alerts, and integration with UPS management platforms — no hunting for a management card SKU after installation.
- Rack-Mount Form Factor: Designed for standard 19-inch rack deployment, keeping power protection co-located with the equipment it serves. No separate floor-standing UPS footprint to plan for in tight raised-floor or open-frame rack environments.
- Scalable ITA2 Platform: The ITA2 family spans 5KVA to 20KVA in the same product line. If you're standardizing on a single UPS platform across server closets (5/8/10KVA) and core data hall rows (15/20KVA), the ITA2 series lets you do that without mixing management interfaces or battery ecosystems.
Integration and Compatibility
The ITA2-20KRT400C is suited for environments running standard 19-inch rack infrastructure with 400/230VAC three-phase power distribution. The included Unity Card supports SNMP v1/v2/v3 and provides integration hooks for common data center infrastructure management (DCIM) platforms. If your operations team monitors UPS status through a network operations center or uses automated shutdown scripts on protected servers, the Unity Card handles both use cases out of the box.
For facilities standardizing on rack-mount UPS systems across multiple rows or cabinets, the ITA2 platform's consistent management interface reduces training overhead when your team provisions or services units across different power tiers. Pairing this unit with appropriately rated rack PDUs downstream keeps the load balanced across phases and simplifies capacity planning.
Before finalizing installation, verify that your upstream three-phase distribution circuit is rated for the ITA2-20KRT400C's input current draw at full load — three-phase UPS at this capacity requires proper circuit protection and appropriate conductor sizing per local electrical code. Coordinate with your facilities or electrical team on input wiring before rack installation.
Frequently Asked Questions
Q: What is the output power capacity of the ITA2-20KRT400C?
A: The ITA2-20KRT400C is rated at 20KVA/20KW. Because it operates at unity (1.0) power factor, the KVA and KW ratings are equal — there is no derating between apparent and real power output.
Q: Does the ITA2-20KRT400C include a network management card?
A: Yes. The ITA2-20KRT400C ships with the Vertiv Unity Card included, enabling SNMP-based network monitoring, web interface access, and integration with data center management systems without requiring a separate card purchase.
Q: What input voltage does the ITA2-20KRT400C require?
A: The ITA2-20KRT400C operates on 400/230VAC three-phase input — standard for European and international data center and industrial power distribution. It is not designed for 208V North American three-phase environments; for those deployments, refer to the 208V variants in the ITA2 family.
Q: Is the ITA2-20KRT400C a rack-mount unit?
A: Yes, it is designed for standard 19-inch rack installation, keeping the UPS co-located with protected equipment rather than requiring separate floor-space allocation.
Q: How does the ITA2-20KRT400C relate to other models in the ITA2 family?
A: The ITA2-20KRT400C is the highest-capacity model in the ITA2 line at 20KVA. The same family includes 5KVA, 8/10KVA, and 15/20KVA variants (some in 208V configurations), allowing consistent platform standardization across different power tiers in the same facility.
The ITA2-20KRT400C is the 400V three-phase answer to a very specific deployment question: how do you protect 20KW of rack load in a European or international data center without sourcing a management card separately or derating your capacity math? The unity power factor is what I always check first on three-phase UPS specs — a 0.9 PF unit at 20KVA only gives you 18KW, and that gap bites you when racks fill up faster than the refresh cycle allows. This unit closes that gap entirely.
Technical Highlights:
- 20KVA/20KW Unity PF: 1:1 KVA-to-KW ratio eliminates derating calculations — plan your circuit at 20KW and that's your actual usable capacity under load.
- 400/230VAC 3-Phase Architecture: Native fit for EU and international three-phase distribution; no step-down transformer required, which removes a failure point and reduces rack footprint.
- Unity Card Included: SNMP monitoring and web-based management out of the box — a meaningful cost and logistics reduction compared to units that ship card-slot-empty.
Deployment Considerations:
- Confirm upstream three-phase circuit capacity and conductor sizing before installation — at 20KW full load, input current draw on a 400V three-phase feed requires proper breaker and wire sizing per local electrical code; this is a facilities coordination step, not a plug-and-play install.
- This is a 400V three-phase model — it is not interchangeable with the 208V ITA2 variants. If your facility runs North American 208V three-phase distribution, you need a different model from the ITA2 family.
The ITA2-20KRT400C is the right spec for a European colocation row or an international industrial control room where 400V three-phase distribution is standard, rack density is high, and your NOC team needs SNMP visibility without an add-on card budget line.
