Vertiv PSI5-2200RT120TAA 1920W 2U Line-Interactive Rackmount UPS
Overview
The Vertiv Liebert PSI5-2200RT120TAA is a 1920VA/1920W line-interactive uninterruptible power supply built for 2U rackmount deployments where power conditioning, runtime reliability, and TAA compliance are non-negotiable. At 96% efficiency in normal mode, it keeps operating costs in check on always-on infrastructure — NVR arrays, PoE switch stacks, access control servers, and edge computing nodes that simply cannot tolerate a dirty power event or an unplanned outage. The PSI5-2200RT120TAA (often searched as PSI5 2200RT120TAA) ships with an L5-20P input plug and a mixed output bank of six 5-15R and one L5-20R receptacles, covering the full range of rack-mounted and tower devices typically deployed in a mid-size security or IT room.
Line-interactive topology with automatic voltage regulation (AVR) means the unit continuously corrects voltage sags and surges without switching to battery — a critical distinction from standby UPS designs in environments where utility power dips frequently but rarely fails outright. Your connected equipment sees stable 120 VAC output regardless of what the building feed is doing, and battery reserve is preserved for actual outages rather than being cycled on every brownout.

Key Features
- 1920VA / 1920W Full Unity Power Factor: A unity power factor rating means the VA and watt ratings are identical — no derating calculation needed when sizing for modern switching power supplies in servers, NVRs, or PoE switches. What you see is what you get for load planning.
- 96% Efficiency in Normal Mode: At full load, the PSI5-2200RT120TAA loses less than 80W as heat — meaningful when this unit runs 24/7/365 in a sealed equipment room. Lower heat output also reduces HVAC load, a secondary cost benefit in high-density closets.
- Line-Interactive AVR Topology: Automatic voltage regulation corrects under- and over-voltage conditions on the input feed without touching the battery. In buildings with weak or variable utility power — common in older commercial and industrial facilities — this topology extends battery service life significantly compared to standby designs that cycle battery on every brownout.
- Mixed Output Bank (6x 5-15R + 1x L5-20R): The seven-outlet configuration handles a realistic rack mix: six standard NEMA 5-15R outlets cover most 1U servers, managed switches, and access control panels, while the L5-20R provides a dedicated higher-draw circuit for devices that demand it. No adapter chains needed for a typical mid-density rack.
- L5-20P Input Plug: The twist-lock L5-20P input is the correct choice for rack PDUs and dedicated UPS circuits — it won't accidentally disconnect under vibration or cable stress, and it maps directly to the 20A dedicated circuits standard in data closets and security equipment rooms.
- TAA Compliance: The TAA designation means this unit is compliant with the Trade Agreements Act — a hard procurement requirement for federal, state, and municipal contracts, as well as many education and healthcare purchasing programs. If your bid spec requires TAA, this is the model to quote; non-TAA variants in the same family will not pass procurement review.
- UL 1778 / c-UL-us Listed, FCC Part 15 Class B: UL 1778 is the recognized UPS safety standard; c-UL-us listing covers both US and Canadian markets without separate certification. FCC Part 15 Class B limits emissions to residential interference thresholds — the more stringent of the two FCC classes — which matters in mixed-use facilities where RF interference can affect access card readers and wireless devices co-located in the same room.
- 2U Rackmount Form Factor (17.2 in W × 3.5 in H × 24.8 in D): Standard 19-inch rack width at 2U height. The 24.8-inch depth is worth checking against your rack's usable depth — shallow wall-mount enclosures and some shorter open-frame racks may not accommodate it without a shelf extender.
- Operating Temperature Up to 40°C: Rated for environments up to 40°C (104°F), which covers most conditioned equipment rooms and IT closets. Not rated for unconditioned outdoor or warehouse deployments where summer ambient temps can exceed this threshold.
Integration and Compatibility
The PSI5-2200RT120TAA fits standard 19-inch rack infrastructure and connects upstream to any 20A, 120 VAC dedicated circuit via its L5-20P input. The output bank supports direct connection to rack PDUs, individual server and switch power supplies, and access control or security appliances drawing from standard 5-15R receptacles. For rackmount UPS systems deployed in security operations centers or server closets, pair this unit with a monitored rack PDU downstream to gain per-outlet switching and metering without replacing the UPS itself.
TAA compliance makes the PSI5-2200RT120TAA a direct fit for government and institutional procurement vehicles. Verify that your rack PDU and any upstream distribution equipment also carry TAA compliance if the full bill-of-materials is subject to review — a single non-compliant component in the power chain can invalidate a TAA bid. For guidance on sizing UPS capacity to your actual connected load, review a power protection planning guide before finalizing your configuration.
For installations deploying multiple UPS units across a security equipment room, consider pairing with a compatible network management card if remote monitoring and graceful shutdown are required — verify compatibility with this specific PSI5 platform before purchasing.
Frequently Asked Questions
Q: Is the PSI5-2200RT120TAA TAA compliant?
A: Yes. The TAA designation in the model number confirms this unit is Trade Agreements Act compliant, making it eligible for federal, state, municipal, and many institutional procurement contracts that require domestic or TAA-country sourcing.
Q: What is the actual watt rating of the PSI5-2200RT120TAA, and does it derate like older UPS units?
A: The PSI5-2200RT120TAA is rated at 1920VA and 1920W — a unity power factor of 1.0. There is no derating between VA and watts, so your full 1920W is available for connected load. This simplifies capacity planning for modern switching power supplies.
Q: What output receptacles does the PSI5-2200RT120TAA provide?
A: The unit provides six NEMA 5-15R receptacles and one NEMA L5-20R receptacle, for a total of seven outlets. The input is a NEMA L5-20P twist-lock plug requiring a dedicated 20A, 120 VAC circuit.
Q: What is the topology of the PSI5-2200RT120TAA — is it true online double-conversion?
A: No. The PSI5-2200RT120TAA uses line-interactive topology with automatic voltage regulation (AVR). It continuously corrects voltage without switching to battery, which preserves battery life in environments with frequent sags or surges. True online double-conversion is a different topology found in higher-tier UPS platforms.
Q: What are the UL and regulatory certifications for this unit?
A: The PSI5-2200RT120TAA carries UL 1778 and c-UL-us listings (covering both US and Canadian markets) and meets FCC Part 15 Class B emissions limits — the more stringent residential-level EMI classification.
Q: Will the PSI5-2200RT120TAA fit in a standard 2-post or 4-post rack?
A: The unit is 17.2 inches wide (standard 19-inch rack) and 3.5 inches tall (2U). Its depth of 24.8 inches requires verification against your rack's usable interior depth — short-depth wall-mount enclosures and some compact open-frame racks may not accommodate it without an extension shelf.
The PSI5-2200RT120TAA is the unit I recommend when a security integrator needs TAA-compliant power protection for a mid-density rack and can't afford the double-conversion premium. The 96% normal-mode efficiency spec is the number I point to first — at 24/7 runtime in a conditioned equipment room, that efficiency delta versus a 90–92% unit adds up to real dollars on the annual power bill, and less heat means less HVAC load fighting against your battery's operating temperature ceiling.
Technical Highlights:
- Unity Power Factor (1920VA = 1920W): No derating math required. Size your connected load to 1920W and you're done — unlike legacy UPS units with 0.7–0.8 power factors where the watt capacity was far below the VA label.
- AVR Line-Interactive Topology: Voltage sags and surges are corrected in real time without a battery transfer — which means in a building with marginal utility power, the battery stays full and ready for a real outage rather than being partially discharged on every brownout cycle.
- Mixed Output Bank: Six 5-15R outlets handle the bulk of rack gear; the single L5-20R is there for the one device in the rack that actually needs it. This is a more useful configuration than all-5-15R designs that force adapters on every L5-20R device.
Deployment Considerations:
- Verify your rack's interior usable depth before ordering — 24.8 inches is longer than many wall-mount enclosures allow, and it's a frustrating discovery on installation day.
- The 40°C operating temperature ceiling is tight for unconditioned spaces. If your equipment closet isn't climate-controlled and ambient temps can peak above 104°F in summer, move to a unit rated for higher ambient or address the cooling first.
This unit fits best in a TAA-required government or municipal security equipment room — a 2U slot, a dedicated 20A circuit, and a mixed rack of NVRs, managed switches, and access control servers that need both clean power and a credible paper trail for procurement compliance.
