Vertiv ITA2LI-40KRT208V23UPN 20KVA 208V 2+0 Parallel Li-ion UPS Bundle
Overview
The Vertiv ITA2LI-40KRT208V23UPN is a 20KVA / 208V lithium-ion UPS bundle configured for 2+0 parallel operation — meaning two UPS units working together to deliver combined capacity rather than N+1 redundancy. This architecture is suited to data centers, server rooms, and dense IT environments where load growth is anticipated and battery refresh cycles are a total-cost-of-ownership concern. The ITA2LI-40KRT208V23UPN ships as a pre-configured bundle, consolidating the hardware ordering process for parallel deployments that would otherwise require separate unit and accessory procurement.
The ITA2 platform's lithium-ion chemistry is the defining operational difference from lead-acid predecessors in the same power class. Li-ion cells charge faster after a discharge event, tolerate more charge cycles before capacity degradation, and operate across a wider ambient temperature range — all directly relevant to reducing planned maintenance windows and cooling overhead in rack-dense installations.
Key Features
- Lithium-Ion Battery Chemistry: Li-ion cells deliver significantly longer service life and faster recharge compared to VRLA alternatives, reducing planned battery replacement cycles and the associated labor and disposal costs over a multi-year deployment.
- 2+0 Parallel Bundle: The ITA2LI-40KRT208V23UPN bundles two units for parallel operation, providing combined 40KVA aggregate capacity at 208V — appropriate for high-density compute rows where a single-unit ceiling would require a larger, less flexible frame.
- 208V Three-Phase Input/Output: Native 208V operation matches standard North American data center PDU infrastructure, simplifying integration without step-up or step-down transformers.
- Rack-Mount Form Factor: The ITA2 series is designed for standard 19-inch rack installation, keeping UPS hardware co-located with the load it protects and minimizing cable runs.
Integration and Compatibility
The ITA2 platform is designed for integration into existing data center power infrastructure at 208V. Parallel configurations require compatible parallel kits and appropriately rated PDUs downstream. Consult Vertiv's Vertiv power protection catalog for compatible external battery cabinets, parallel communication cables, and UPS accessories before finalizing the deployment bill of materials. For large-scale power planning, review the power protection buying guide to size the installation correctly against actual load measurements.
Frequently Asked Questions
Q: What does the 2+0 configuration mean for the ITA2LI-40KRT208V23UPN?
A: 2+0 means both units contribute to total capacity — there is no redundant spare unit held in reserve. The combined output is approximately 40KVA at 208V. If you need N+1 redundancy, a 2+1 parallel configuration would require an additional unit.
Q: Does this bundle include all hardware needed for parallel operation?
A: The ITA2LI-40KRT208V23UPN is a pre-configured bundle. Verify exact kit contents with your order confirmation or Vertiv product documentation before installation, as parallel configurations typically require dedicated interconnect cables and synchronization hardware.
Q: What are the advantages of lithium-ion over lead-acid in this power class?
A: Li-ion batteries generally offer a longer service life, faster recharge after a discharge event, lower weight per kWh of stored energy, and tolerance for higher ambient temperatures — reducing cooling requirements and planned replacement cycles compared to VRLA alternatives in the same kVA class.
Q: Is the ITA2LI-40KRT208V23UPN suitable for three-phase environments?
A: The ITA2 series at 208V is designed for North American data center infrastructure. Confirm input phase configuration requirements with Vertiv specifications or a qualified power engineer before installation, as paralleled UPS units have specific upstream distribution requirements.
The ITA2LI-40KRT208V23UPN is the bundle SKU to evaluate when you are planning a 2+0 parallel deployment on a 208V distribution backbone and want lithium-ion chemistry from the start — not as an upgrade retrofit. The Li-ion specification is the primary reason to choose this configuration over a comparably rated lead-acid ITA2 stack: shorter recharge windows after a utility event matter when you are running tight maintenance schedules across a multi-tenant data hall.
Technical Highlights:
- Parallel 2+0 Architecture: Two units operating in aggregate deliver combined 40KVA capacity at 208V — sized for high-density compute rows that exceed single-unit limits without stepping up to a larger, more expensive frame class.
- Lithium-Ion Chemistry: Li-ion cells tolerate more charge/discharge cycles before capacity loss compared to VRLA, translating directly to fewer planned battery replacement events over the installation's lifecycle — a meaningful OPEX reduction at this power class.
- 208V Native Output: Matches standard North American data center PDU infrastructure without transformer intervention, keeping the distribution path clean and losses minimal.
Deployment Considerations:
- Parallel UPS configurations require verified synchronization cabling and compatible bypass panel infrastructure upstream — confirm all parallel kit components are included in this bundle or ordered separately before scheduling installation.
- Li-ion UPS units at this capacity class carry a higher upfront cost than equivalent VRLA configurations; build the TCO case around reduced battery replacement cycles and potential cooling savings before presenting to procurement.
The ITA2LI-40KRT208V23UPN is the right specification for greenfield data center rows or colocation cage builds where lithium-ion chemistry is a design requirement and 208V parallel capacity needs to scale without a platform change.
