Vertiv ITA2LI-20KRT208V23URN 20KVA 208V 1+1 Parallel Li-ion UPS Bundle
Overview
The Vertiv ITA2LI-20KRT208V23URN is a 20KVA, 208V rack-mount UPS bundle configured for 1+1 parallel redundancy with lithium-ion battery technology. Vertiv's Liebert ITA2 line spans 5KVA through 20KVA at 208V, making this the top-capacity configuration in the family — the right pick for data center rows, server rooms, or critical infrastructure racks where a single UPS failure cannot be a single point of outage. The 1+1 parallel architecture means a second unit runs hot alongside the primary: if one module faults, the other carries the full 20KVA load without interruption.
Key Features
- 20KVA at 208V: The Liebert ITA2 family tops out here — this is the configuration for high-density rack environments where lower capacities in the 5KVA or 8/10KVA tiers would require multiple independent UPS units and more complex bypass management.
- 1+1 Parallel Redundancy: Two matched units share the load under normal conditions; either can carry 100% alone. This N+1 approach protects against both module failure and scheduled maintenance windows without a planned outage.
- Lithium-Ion Battery Technology: Li-ion chemistry runs longer between replacements than VRLA, occupies less physical space per kilowatt-hour of stored energy, and tolerates higher ambient temperatures — all relevant factors in dense rack environments with constrained thermal management.
- Rack-Mount Form Factor: The ITA2LI-20KRT208V23URN is built for standard 19-inch rack deployment, keeping the UPS co-located with the load it protects rather than requiring floor-standing cabinet space.
- 208V Input/Output: Matched to three-phase-derived 208V infrastructure common in North American data centers and server rooms — no step-up transformer needed in properly provisioned environments.
- Bundle Configuration: Sold as a complete parallel bundle, reducing sourcing complexity when provisioning a redundant pair versus purchasing and matching individual units separately.
Deployment Context
The ITA2LI-20KRT208V23URN suits environments where runtime, redundancy, and rack density all matter simultaneously: colocation cage buildouts, enterprise server room refreshes, or edge computing deployments where a floor-standing modular UPS is physically impractical. Contact pre-sales engineering to confirm load calculations, runtime requirements at your actual draw, and compatibility with your existing PDU and bypass infrastructure before ordering a parallel bundle of this capacity.
Frequently Asked Questions
Q: What is the power capacity of the ITA2LI-20KRT208V23URN?
A: This bundle is rated at 20KVA at 208V, the highest capacity configuration in the Liebert ITA2 rack UPS family, which also includes 5KVA and 8/10KVA models.
Q: What does the 1+1 parallel configuration mean for this UPS bundle?
A: 1+1 parallel means two UPS units are deployed together and share the load. Each unit is capable of carrying the full load independently, so if one fails or requires maintenance, the other sustains power without interruption.
Q: Why choose lithium-ion over VRLA batteries in the ITA2 platform?
A: Lithium-ion batteries generally offer longer service life, a smaller footprint per stored kilowatt-hour, and better performance at elevated ambient temperatures compared to traditional VRLA (valve-regulated lead-acid) batteries — relevant for high-density rack environments with limited cooling headroom.
Q: Is the ITA2LI-20KRT208V23URN a rack-mount unit?
A: Yes. The ITA2 platform in this SKU is designed for standard 19-inch rack installation.
Q: Does this bundle include everything needed for a parallel redundant deployment?
A: The ITA2LI-20KRT208V23URN is sold as a parallel bundle. Confirm exact package contents, inter-unit cabling, and bypass requirements with pre-sales engineering prior to ordering, as site-specific PDU and bypass infrastructure may need to be sourced separately.
The ITA2LI-20KRT208V23URN sits at the top of the Liebert ITA2 rack UPS capacity range at 20KVA/208V — and the 1+1 parallel bundle configuration is the detail that matters most for critical deployments. This isn't just two units sharing a load; it's a hot-standby architecture where either module can absorb 100% of the connected load the moment the other drops offline, without a transfer gap that would stress sensitive server and storage hardware.
Technical Highlights:
- 20KVA Top-Tier Capacity: At the ceiling of the ITA2 family, this configuration handles high-density rack loads that would require awkward multi-unit management at the 8/10KVA tier — consolidating protection under a single parallel pair simplifies both monitoring and bypass procedures.
- Li-ion Chemistry: Compared to VRLA, lithium-ion tolerates higher ambient temperatures without accelerated degradation — a practical advantage when rack cooling is running at margin, which is exactly when power protection is most critical.
- 208V Alignment: Native 208V matches the standard single-phase leg from three-phase North American distribution without transformer overhead — straightforward to connect, no derating surprises at the PDU.
Deployment Considerations:
- A 1+1 parallel deployment at 20KVA requires careful upfront load budgeting — confirm your actual connected load leaves sufficient headroom on a single module before commissioning, since the redundancy architecture only holds if neither unit is already near capacity under normal shared operation.
- Parallel UPS bundles of this scale typically require coordinated bypass switching and matched inter-unit communication cabling — verify all required interconnects are included in the bundle or accounted for separately before the installation date.
The ITA2LI-20KRT208V23URN is a strong fit for enterprise server room buildouts and colocation cage deployments where rack space is constrained, runtime expectations are high, and an unplanned UPS module failure cannot result in a production outage.
