Vertiv™ Liebert® ITA2 | ITA-20kVA-3 PHASE | Indigi Power & Cooling
The Vertiv Liebert ITA2 20kVA is a rack or tower online double-conversion UPS delivering 20 kW at unity (1.0) power factor with three-phase power, protecting critical loads across Australia. It runs true VFI double conversion with up to 96.5% efficiency, or up to 99% in ECO mode, and is supplied, installed and maintained by Indigi Power and Cooling, an Indigenous and Veteran-owned specialist.
The Vertiv Liebert ITA2 is a fully digital, online double-conversion UPS built for data centre racks and critical three-phase distribution. The 20 kVA model combines a compact rack-tower chassis with unity output power factor and best-in-class efficiency, giving you clean, continuous power with low running costs. It is part of the ITA2 5kVA to 40kVA family, all sharing the same control platform, communications and battery approach.
At 20 kVA it is built for populated racks and small data centres, taking a three-phase input and feeding either single-phase or three-phase loads, so one platform can protect a mixed rack of servers, storage and network gear.
Why the ITA2 20kVA leads
Unity power factor
Delivers the full 20 kW of real power at unity power factor, so every kVA is usable watts for modern IT loads.
Up to 96.5% efficient
True double-conversion efficiency up to 96.5%, and up to 99% in ECO mode, cutting running costs and heat.
Rack or tower
A 3U rack or tower chassis that installs either way, so it fits a rack row or stands alone in a comms room.
Wide input window
A wide input voltage and frequency range (50/60 Hz (range 40 to 70 Hz)) rides through unstable mains and generator supply, sparing the battery.
Fast battery recharge
A powerful charger (13 A) restores runtime quickly after an outage, so the UPS is ready for the next event.
Smart, quiet cooling
Intelligent variable-speed fans keep noise to around 60 dBA and save energy at partial load.

True online double-conversion protection
The ITA2 20kVA is a VFI-SS-111 online double-conversion UPS, which means incoming mains is rectified to DC and rebuilt into a clean sine wave by the inverter, and your load always runs from that inverter. There is no transfer time when the mains fails, and mains-borne problems such as sags, spikes, frequency drift and harmonics never reach your equipment. For data centre racks and critical three-phase distribution, that is the difference between conditioned, uninterrupted power and a UPS that only reacts once a problem has already passed through.
Efficiency and running costs
Running cost matters over the life of a UPS. The 20 kVA reaches up to 96.5% efficiency in full online double-conversion mode, so very little of your energy is lost as heat, which also reduces the cooling load in the room. Where the supply is stable enough, ECO mode lifts efficiency to up to 99% for further savings. Intelligent variable-speed fans add to this by running only as fast as the load and temperature require, keeping noise to around 60 dBA and cutting energy use at partial load.

Indicative battery runtime
Runtime scales with the number of internal battery modules. The figures below are approximate autonomy at full load and at half load, based on fully charged batteries at 25 degrees C. For a precise runtime for your load, use our UPS runtime and battery calculator.
| Battery modules | At full load (20 kVA) | At half load |
|---|---|---|
| 4 modules | 6.9 min | 18.3 min |
| 6 modules | 12.3 min | 32.3 min |
| 8 modules | 18.5 min | 46.8 min |
| 10 modules | 25.3 min | 61.1 min |
Communications and monitoring
The 20 kVA integrates with your monitoring and building management systems out of the box. It provides voltage-free (dry) contact ports, a USB interface and a Vertiv IntelliSlot bay for an SNMP, Modbus or relay card, plus an integrated network port with HTTP access for browser-based monitoring. That lets your team see UPS status, load and battery health remotely and trigger a graceful server shutdown before the battery is exhausted. Programmable output terminals let you shed non-critical outlets first during a long outage, protecting the most important equipment.
Battery management and extended runtime
A wide input voltage window lets the 20 kVA keep drawing from the mains or a generator across a broad range before it calls on the battery, which reduces cycling and prolongs battery life. When backup is needed, a powerful charger (13 A) restores the string quickly after an outage. Automatic and manual self-tests flag a weak battery early, and temperature-compensated charging protects battery life in warm rooms. Runtime scales with battery modules or external cabinets, so the same UPS can cover a brief generator handover or a longer ride-through.
How the ITA2 20kVA compares
| Feature | Liebert ITA2 20kVA | Typical rack online UPS |
|---|---|---|
| Topology | Online double conversion (VFI-SS-111) | Often line-interactive at this size |
| Output power factor | unity (1.0) | Commonly 0.8 to 0.9 |
| Peak efficiency | up to 96.5% (up to 99% ECO) | Typically 92 to 95% |
| Form factor | Rack or tower, 430 x 570 x 130 mm | Usually rack-only or tower-only |
Sizing the ITA2 20kVA for your site
For a rack drawing up to 20 kW, the 20 kVA gives you three-phase input with the option of single-phase or three-phase output, so a single unit can protect a rack that mixes both. Size to your measured load and add battery cabinets for extended runtime.

Frequently asked questions
Is the Vertiv Liebert ITA2 20kVA a true online UPS?
Yes. It is a true online double-conversion UPS classified VFI-SS-111, so the load always runs from the inverter with zero transfer time and full conditioning, not just battery backup during an outage.
What power factor and real power does the 20kVA deliver?
It delivers 20 kW at unity (1.0) power factor, so the full kVA rating is usable watts for modern IT loads.
Can the ITA2 20kVA be rack or tower mounted?
Yes. The 430 x 570 x 130 mm (3U rack or tower) chassis mounts in a standard rack or stands as a tower, so it fits a rack row or a floor position in a comms room.
How long will it run on battery?
Runtime depends on load and the number of battery modules or external cabinets fitted. See the runtime table above, or use our UPS runtime and battery calculator, or ask Indigi to size it for your load.
Do I need an electrician to install it?
A three-phase UPS of this size should be installed and commissioned by a licensed electrician under AS/NZS 3000. Indigi provides installation, commissioning and ongoing maintenance across Australia.
Does Indigi service the Liebert ITA2 across Australia?
Yes. Indigi supplies, installs and maintains the ITA2 range from hubs in Brisbane, Sydney and Melbourne, with national coverage including genuine Vertiv parts and battery replacement.
