Vertiv Liebert ITA2 UPS Systems

Vertiv Liebert ITA2 online UPS systems

The Vertiv Liebert ITA2 is a fully digital, online double-conversion UPS series built for IT racks, edge sites, control rooms, and other applications that need clean, continuous power. Every model in this collection delivers true online double-conversion with a pure sine wave output, so the load is always fed from a regenerated waveform rather than switched over to battery only when utility power fails. Within the Liebert lineup, ITA2 sits in the mid-power, single-cabinet tier: higher capacity than entry desktop/tower units, but more compact and self-contained than Vertiv's larger modular three-phase platforms. The systems carried here run from 8 kVA up to 15 kVA, in rack/tower chassis (RT in the part numbers), making the series a flexible fit whether you are sizing a new rack, refreshing an edge closet, or standardizing on a single platform across sites.

How to choose

VA versus watts. A UPS has two capacity limits and your load must fit under both. Volt-amps (VA) is the apparent-power ceiling; watts (W) is the real-power ceiling. The ratio between them is the unit's power factor. The 10 kVA model in this series is rated at 10,000 W (a unity-power-factor design), while the 8 kVA tower/rack-convertible unit is rated 7,200 W. Always check both numbers on the product page, size to the larger of your two requirements, and leave headroom for growth.

Runtime expectations. Published runtimes scale with load: each model runs longer at half load than at full load. For example, the 8 kVA convertible model is rated 33 minutes at half load and 13 minutes at full load, while the 10 kVA model is rated 21 minutes and 8 minutes respectively. If you need longer holdover, every model in this collection is extended-runtime capable and accepts additional battery cabinets.

Topology. The entire ITA2 series in this collection is online double-conversion. Unlike line-interactive designs, an online UPS continuously rebuilds the output waveform, protecting connected equipment from sags, surges, frequency drift, and brownouts. That makes it the right choice for sensitive servers, storage, network cores, and instrumentation that cannot tolerate transfer gaps.

Rack versus tower. Every model here is a rack/tower design: mount it in a standard server cabinet, or stand it on the floor in a closet or wiring room today and rack-mount it later.

Why this series

• Online double-conversion protection with a pure sine wave output on every model.
• Capacity from 8 kVA to 15 kVA to cover single racks through denser deployments.
• Rack/tower chassis across the range, including a lithium-ion option (ITA2LI-08KRT2085UN) for longer service life and reduced weight.
• Extended-runtime capable across the range, so holdover can grow with additional battery cabinets.
• 208V and 208/120V output options to match data-room and IT power distribution.

Can I rack-mount these units?
Yes. Every model here is a rack/tower design that can be deployed either way.

Can I extend the runtime?
Yes. All models in this collection are extended-runtime capable and accept additional battery cabinets for longer holdover.

Is there a lithium-ion option?
Yes. The ITA2LI-08KRT2085UN is an 8 kVA lithium-ion model, rated 28 minutes at half load and 14 minutes at full load.
