Vertiv ITA2-40KRT208V37UPRN 20kVA 3-Phase Online Double-Conversion Redundant UPS Bundle
Overview
The Vertiv Liebert ITA2-40KRT208V37UPRN is a 20kVA/20kW three-phase online double-conversion UPS bundle configured for 2+1 parallel redundancy on 208/120VAC (220/127VAC) 3-phase 4-wire infrastructure. Designed for data centers, server rooms, and critical network deployments where downtime is not an option, this rack/tower convertible unit ships complete with SNMP management and four pairs of VRLA batteries. The ITA2-40KRT208V37UPRN delivers clean sine wave power continuously — not just during outages — making it the correct choice for sensitive compute and networking loads up to 40kVA when paired in a full 2+1 parallel cluster. Explore the full Vertiv power protection lineup for compatible accessories and expansion options.
Key Features
- Online Double-Conversion Technology: Unlike standby or line-interactive designs, the ITA2 continuously regenerates output power — every microsecond. Voltage sags, spikes, frequency drift, and brownouts are blocked at the input, never reaching your servers or networking gear.
- 2+1 Parallel Redundancy: Two units carry the load while a third stands ready. If one unit faults, the cluster absorbs load without interruption — critical for environments where a single UPS failure cannot be a site-down event. This bundle is sized and pre-configured for that architecture up to 40kVA at 208V.
- Unity Power Factor (1.0): A 1.0 power factor means 20kVA equals 20kW of real usable capacity. UPS units with 0.8 or 0.9 power factors deliver 16–18kW on the same kVA rating — a meaningful difference when sizing for dense compute racks. No derating required here.
- 99% Efficiency in Eco Mode: Running at 99% efficiency in eco mode versus 93%+ in full double-conversion, the efficiency gain cuts operating costs on always-on infrastructure. For a 20kW load running 8,760 hours per year, even a 4-point efficiency difference represents thousands of dollars annually in energy savings.
- ENERGY STAR 2.0 Certified: Meets ENERGY STAR 2.0 efficiency standards — relevant for facilities with sustainability mandates, green building certifications, or utility rebate programs targeting UPS infrastructure.
- Hot-Swappable VRLA Batteries: The four VRLA battery pairs can be replaced without powering down the load. In a redundant cluster, battery maintenance no longer requires a maintenance window — technicians swap batteries under live load while the parallel units hold the critical systems.
- SNMP Network Management: Built-in SNMP support integrates with enterprise NMS platforms (SolarWinds, PRTG, Nagios, and compatible systems) for real-time monitoring of UPS status, battery health, load percentage, and alarm conditions — without requiring a separate management card in most configurations.
- Rack/Tower Convertible Form Factor: Installs in a standard equipment rack or freestanding as a tower, giving deployment flexibility for environments where rack space is constrained or the unit needs to live outside a rack enclosure.
- Scalable Battery Runtime: The VRLA battery configuration supports extended runtime scaling — pair with compatible external battery cabinets when application runtime requirements exceed what the internal packs deliver.
Integration and Compatibility
The ITA2-40KRT208V37UPRN operates on 208/120VAC three-phase 4-wire input, standard in North American commercial and data center electrical infrastructure. SNMP connectivity supports integration with most enterprise network management infrastructure and building management systems. The optional maintenance bypass cabinet option noted in the product documentation supports enhanced availability during UPS servicing — confirm compatibility with your specific installation before ordering.

Frequently Asked Questions
Q: What is the actual usable power output of the ITA2-40KRT208V37UPRN?
A: This unit delivers 20kW of real power at a unity power factor (1.0), meaning there is no derating between the kVA and kW ratings. The 2+1 parallel bundle supports up to 40kVA/40kW total cluster capacity with one unit reserved for redundancy.
Q: Does the ITA2-40KRT208V37UPRN require a dedicated input circuit?
A: Yes. The unit operates on 208/120VAC (or 220/127VAC) three-phase 4-wire input. Consult a licensed electrician for proper circuit sizing and breaker coordination before installation.
Q: Can the batteries be replaced without shutting down the connected load?
A: Yes. The ITA2 features hot-swappable, user-replaceable VRLA batteries. In a 2+1 redundant configuration, battery maintenance can be performed without interrupting the protected load.
Q: What is the warranty on the ITA2-40KRT208V37UPRN?
A: The ITA2-40KRT208V37UPRN carries a 2-year manufacturer warranty.
Q: Does the ITA2-40KRT208V37UPRN include network management capability?
A: Yes. The bundle includes SNMP management, enabling integration with enterprise NMS platforms for remote monitoring of UPS status, load, battery condition, and alarms.
Q: Is the ITA2-40KRT208V37UPRN ENERGY STAR certified?
A: Yes. The unit carries ENERGY STAR 2.0 certification, relevant for green building programs, sustainability reporting, and applicable utility efficiency rebate programs.
The ITA2-40KRT208V37UPRN is the right answer when you need parallel redundancy at the UPS layer without building a custom multi-unit architecture from scratch. The 2+1 configuration means the cluster runs two units under load and holds one in reserve — so a single UPS fault is a non-event, not a page at 2 AM. The unity power factor (1.0) is the spec I always check first on three-phase UPS quotes: it tells you immediately whether the kVA number is honest or padded.
Technical Highlights:
- Unity Power Factor (1.0): Full 20kW usable from a 20kVA rating — no silent derating. A competitor unit at 0.8 PF would give you 16kW from the same headline number.
- Dual Efficiency Modes: 93%+ in full online double-conversion for maximum protection, 99% in eco mode for always-on deployments where input power quality is stable — gives operators a meaningful choice based on site conditions.
- Hot-Swap VRLA Batteries: Four battery pairs, user-replaceable under load. In a redundant cluster this means battery PM doesn't require a maintenance window — the parallel unit holds the load while you swap.
Deployment Considerations:
- Three-phase 4-wire 208V input is non-negotiable — verify your electrical infrastructure before quoting this unit into a project. Single-phase environments are not compatible.
- The optional maintenance bypass cabinet is noted in documentation but not included in this bundle — budget and spec it separately if your uptime SLA requires servicing the UPS without transferring load to a generator or alternative source.
This bundle is sized for colocation edge pods, mid-tier data center rows, and critical surveillance or access control infrastructure where a single-UPS topology is an unacceptable risk and the electrical plant is already three-phase 208V.
