Vertiv ITA2-40KMBC42 20kVA Double-Conversion Online UPS
Overview
The Vertiv Liebert ITA2-40KMBC42 is a 20 kVA / 20 kW double-conversion online UPS in a dual-form-factor rack/tower chassis, designed for mid-size data rooms, edge deployments, and high-density equipment racks where input power quality is inconsistent and downtime is not an option. Part of the Vertiv Liebert ITA2 series, the ITA2-40KMBC42 delivers continuous voltage regulation across a wide 173V–498V AC input range — covering 380V, 400V, and 415V three-phase environments — without switching to battery. That means your connected equipment rides through line sags, swells, and frequency excursions that would trip a line-interactive UPS.
At up to 99% efficiency in eco-mode operation, this unit is among the more efficient online UPS systems in its class — relevant when you're sizing cooling loads and calculating annual power costs for a 24/7 installation. The 40–70 Hz input frequency window makes it suitable for generator-backed environments where frequency wanders outside the 47–53 Hz range a conventional UPS tolerates.
Key Features
- Double-Conversion Online Topology: Unlike line-interactive or standby designs, the ITA2-40KMBC42 continuously regenerates a clean sine wave output — load never sees raw utility power. Transfer time on utility loss is zero milliseconds; the inverter is already running the load before the event happens. This matters for sensitive networking and storage equipment that reacts badly to even short voltage drops.
- 20 kVA / 20 kW Capacity at Unity Power Factor: Unity power factor (kVA = kW) means no derating for modern switched-mode power supplies. A 20-rack-unit compute deployment drawing 18 kW has genuine headroom here, rather than hitting an invisible wall caused by a 0.8 power-factor-corrected UPS rating.
- Wide Input Range — 173V to 498V AC: This range covers single-phase 230V through three-phase 415V, and extends down to 173V before transferring to battery. Facilities with aging distribution or long cable runs that sag under load benefit directly — fewer unnecessary battery discharges means longer battery service life.
- Up to 99% Efficiency: At 99% efficiency, a 20 kW load loses roughly 200W to heat rather than the 600–800W lost in a typical 92–96% efficient UPS. Across a year of 24/7 operation, that delta translates to meaningful cooling savings and reduced facility power draw — worth calculating before comparing purchase price alone.
- 40–70 Hz Input Frequency Acceptance: Generator sets at startup or under heavy load commonly produce frequency excursions outside the 47–53 Hz range. The ITA2-40KMBC42's 40–70 Hz window allows it to run generator-backed without nuisance battery transfers during generator stabilization.
- Intelligent Card Slot + USB Interface: The intelligent card slot accepts optional SNMP, Modbus, and relay cards — meaning network management capability is field-installable rather than requiring a pre-configured model. USB provides direct local management and firmware updates without a network connection.
- LCD Display: Local status visibility without requiring a laptop or network access. Relevant during commissioning or troubleshooting in environments where remote access hasn't been stood up yet.
- Certifications — UL, CE, VFI-SS-111: The IEC 62040-2 VFI-SS-111 classification specifically certifies voltage and frequency independence — meaning the output holds regulated voltage and frequency regardless of input conditions. UL listing covers North American safety requirements; CE covers European installations. This unit also carries EN/IEC/AS/BS 62040-2 and 62040-4 compliance.
- Rack/Tower Form Factor — 50.71 lbs: At under 51 lbs, a two-person installation in a standard equipment rack is manageable. The 5.1
