Vertiv ITA2-40KMBC40 20kVA Online Double Conversion Rack/Tower UPS
Overview
The Vertiv ITA2-40KMBC40 is a 20kVA/20kW online double-conversion UPS built for IT rooms, edge deployments, and branch offices where power quality failures are not an option. Operating at unity power factor (1.0 output), every kilovolt-amp of rated capacity translates directly to a kilowatt of usable load — no derating math required. The ITA2-40KMBC40 (often searched as ITA2 40KMBC40) ships in a rack/tower convertible form factor, giving you installation flexibility from day one without purchasing additional conversion kits.

Key Features
- Online Double Conversion Topology: The UPS regenerates a clean sine wave on the output at all times — incoming voltage sags, swells, and harmonic distortion never reach your equipment. This is the correct topology for server virtualization hosts, storage arrays, and VoIP infrastructure where even brief power anomalies cause session drops or data corruption.
- 20kVA / 20kW at Unity Power Factor: A 1.0 output power factor means the nameplate kVA equals the usable kW — a meaningful distinction when sizing for high-density blade chassis or dense 1U/2U server populations that draw close to their rated wattage. No capacity is wasted on reactive power margin.
- Up to 99% Efficiency in ECO Mode: ECO mode reduces heat output and operating cost substantially compared to conventional double-conversion designs that typically run at 92–96%. For a 20kW load running 24/7, the efficiency delta compounds quickly on the utility bill. Full double-conversion protection is available when ECO mode is bypassed for regulated-environment compliance.
- Wide Input Voltage Acceptance (173–498V AC): The ITA2-40KMBC40 accepts 380V, 400V, 415V, and 230V AC inputs with a tolerance window from 173V to 498V. This range accommodates international facilities, aging distribution infrastructure, and generator sources that commonly run at the high or low edge of nominal voltage — all without switching to battery unnecessarily.
- 40–70 Hz Input Frequency Range: Generator sets, especially during startup and load transient phases, often produce frequency excursions outside the standard 50/60Hz window. The 40–70Hz input acceptance window means the UPS rides through these transients on utility power rather than discharging the battery during every generator test cycle.
- 0.99 Input Power Factor: A near-unity input power factor reduces reactive current draw from the upstream distribution panel, keeping branch circuit loading predictable and minimizing harmonic injection back into the facility wiring — relevant in shared-panel environments alongside sensitive measurement or audio equipment.
- Hot-Swappable Battery Architecture: Batteries can be replaced without shutting down the connected load. In a 24/7 data center or always-on security operations environment, planned maintenance windows for battery replacement create real operational risk. Hot-swap eliminates that exposure.
- Extra-Powerful Integrated Battery Charger: Rapid recharge after an outage shortens the window of reduced runtime on the next event. In facilities with recurring short outages — utility switching, scheduled generator tests — fast recovery matters more than most buyers initially account for.
- Multi-lingual LCD Display: The front-panel display provides local status, load percentage, battery runtime estimate, and alarm conditions without requiring a laptop or network connection on the floor. Useful during physical commissioning and during incidents when network access may be interrupted.
- SNMP, Modbus, and Relay Card Management: Network management options via the expansion slot cover the three most common monitoring paths in enterprise IT: SNMP for NMS/DCIM integration, Modbus for BMS/SCADA connectivity, and dry-contact relay for simple alarm annunciation. This range of options avoids protocol lock-in on mixed-infrastructure sites.
- USB Port: The onboard USB connection supports local management and firmware updates from a laptop without needing the network card installed — useful during initial commissioning or in air-gapped environments.
Integration & Compatibility
The ITA2-40KMBC40 carries UL, CE, VFI-SS-111, and EN/IEC/AS/BS 62040-2/4 certifications, confirming compliance with the IEC 62040 standards relevant to IT and industrial UPS deployments across North American, European, and Asia-Pacific markets. VFI-SS-111 classification confirms true voltage and frequency independent (double-conversion) operation — a distinction that matters when specifying for data center compliance frameworks that require documented power conditioning topology.
Network management integrates through the optional slot-based card, supporting SNMP for enterprise NMS platforms and Modbus for building management systems. Pair with a network management card or automatic transfer switch to round out the power protection stack. For larger deployments requiring monitored power distribution downstream, consider reviewing your rack PDU options alongside this unit.
