Vertiv PSI5-1500RT120TAAN 1500VA/1350W 2U Rackmount Line-Interactive UPS with RDU120 Network Card
Overview
The PSI5-1500RT120TAAN is a 1500VA/1350W line-interactive UPS in a 2U rackmount form factor, purpose-built for IT closets, edge deployments, and security infrastructure stacks where consistent 120VAC power delivery is non-negotiable. The Liebert PSI5 line from Vertiv ships with the RDU120 network management card pre-installed — a detail that matters when you're managing power remotely across distributed sites and don't want to source a card separately or discover the slot is absent after racking the unit. If you're speccing power protection for NVRs, network switches, access control panels, or similar UPS-protected security infrastructure, the PSI5-1500RT120TAAN lands in a practical capacity range for single-rack edge deployments.
Key Features
- 1500VA / 1350W Output: The 0.9 power factor (1350W real power from 1500VA apparent) is competitive for a line-interactive unit and means you're not leaving significant headroom on the table when running high-power-factor server and network loads. Know your connected load in watts, not VA — at 1350W you can carry a fully-loaded 1U server, a managed PoE switch, and a standalone NVR simultaneously without hitting the ceiling.
- Line-Interactive Topology with AVR: Automatic voltage regulation corrects sags and surges without switching to battery, which extends battery life significantly in environments where utility power fluctuates but outright failures are rare. For telecom closets and edge racks on commercial building power, this matters more than it might seem — AVR handles browndowns silently while keeping runtime reserves intact for actual outages.
- Up to 96% Efficiency (Normal Mode): At 96% efficiency, the PSI5-1500RT120TAAN wastes roughly 54W at full load as heat rather than the 100–150W you'd see from a less-efficient unit. In a sealed IDF closet or equipment cabinet, that thermal difference is real — less heat generated means lower ambient temps, quieter fans, and longer component life for everything in the rack.
- RDU120 Network Management Card Included: Remote monitoring and control over the network — load, battery status, runtime estimates, event logging, and graceful shutdown signaling — without an add-on purchase. For security integrators managing distributed sites, this is the feature that separates a managed power device from a passive one. Configure SNMP traps to your NMS or use the web interface directly.
- Six 5-15R Output Receptacles: Six individually accessible NEMA 5-15R outlets on a 5-15P input give you enough drops to cover NVR, switch, access control panel, and ancillary gear in a typical edge security rack. No PDU adapter needed for standard North American equipment.
- TAA Compliance: The -TAAN suffix designates Trade Agreements Act compliance, which is a procurement requirement for federal, state, and many municipal government contracts. If you're bidding on government security projects, this is the variant to spec — the standard PSI5-1500RT120 without the TAA suffix won't satisfy those contracts.
- UL 1778 / c-UL-us Listed, FCC Part 15 Class B: UL 1778 is the UPS-specific standard (not a generic listing) — relevant for AHJ inspections and insurance requirements on commercial installations. FCC Class B means it's rated for residential-density RF environments, so it won't introduce interference issues in mixed-use or light commercial deployments.
- 40°C Maximum Operating Temperature: Rated to 40°C ambient — adequate for most equipment rooms, but worth noting in unconditioned spaces or warm climates. If your rack closet regularly exceeds 35°C in summer, factor in derating or active cooling before sizing the load.
Integration & Compatibility
The PSI5-1500RT120TAAN operates on standard 120VAC North American power infrastructure. The 5-15P input plug connects to any standard 15A outlet or rack-level power distribution without requiring hardwired installation. The included RDU120 card supports SNMP and web-based management, making it compatible with most enterprise NMS platforms. For network video recorders and PoE switch stacks in a 2U-or-less power footprint, the six outlet configuration covers a standard security edge rack without requiring a supplemental PDU. The unit ships in a 2U rackmount chassis at 17.2 in wide × 20 in deep × 3.5 in tall — verify your rail kit compatibility with standard EIA-310 racks before ordering, as Vertiv rail kits are typically sold separately for this product line. Review your UPS selection criteria against your connected load list before committing to this capacity tier.
Frequently Asked Questions
Q: Is the PSI5-1500RT120TAAN TAA compliant?
A: Yes. The -TAAN suffix explicitly designates Trade Agreements Act compliance, making this the correct variant for federal, state, and government-contract security deployments that require TAA-compliant procurement.
Q: Does the PSI5-1500RT120TAAN include a network management card?
A: Yes. The RDU120 network management card is included in the box. It provides remote monitoring, SNMP support, event logging, and graceful shutdown signaling without requiring a separate card purchase.
Q: What is the real power output of the PSI5-1500RT120TAAN?
A: The unit delivers 1350W of real power at a 0.9 power factor from its 1500VA rating. Size your connected load in watts — at 1350W you have enough capacity for a typical security edge rack including NVR, managed PoE switch, and access control hardware.
Q: What input and output receptacles does the PSI5-1500RT120TAAN use?
A: Input is a single NEMA 5-15P plug (standard 15A North American). Output is six NEMA 5-15R receptacles, giving you six protected drops for rack-mounted security equipment without requiring a separate PDU.
Q: What is the operating temperature range of the PSI5-1500RT120TAAN?
A: The unit is rated for ambient operating temperatures up to 40°C (104°F). In unconditioned or warm equipment rooms that regularly approach or exceed this threshold, plan for active cooling or derate the load accordingly.
Q: What certifications does the PSI5-1500RT120TAAN carry?
A: The unit is UL 1778 listed (the UPS-specific standard), c-UL-us listed for Canada, and FCC Part 15 Class B certified. UL 1778 listing is particularly relevant for commercial AHJ inspections and insurance compliance on security installations.
The PSI5-1500RT120TAAN is one of the few units in this capacity tier that ships with the RDU120 network card pre-installed rather than treating it as an upsell — and for multi-site security integrators, that changes the calculus on managed power at the edge. At 96% efficiency in normal mode, this unit generates roughly half the waste heat of a comparable line-interactive competitor at full load, which is a tangible benefit in thermally constrained IDF closets.
Technical Highlights:
- 1350W Real Power at 0.9 PF: The 0.9 power factor rating gives you 1350W usable against a 1500VA nameplate — better than the 0.6–0.7 PF common in older line-interactive units. Plan your connected load list in watts, not VA, to avoid undersizing.
- 96% Normal-Mode Efficiency: At full 1350W load, you're dissipating roughly 54W as heat. That's the difference between needing supplemental cooling in a sealed cabinet and not. In edge deployments without dedicated HVAC, this spec is worth real money.
- Line-Interactive AVR: The automatic voltage regulation topology corrects input sags and surges without triggering a battery transfer — battery stays in reserve for true outages. In commercial facilities with aging electrical infrastructure or frequent HVAC compressor starts, AVR extends effective battery life meaningfully compared to online-double-conversion units that cycle the battery on every minor fluctuation.
Deployment Considerations:
- The unit is rated to 40°C ambient — adequate for conditioned spaces but tight in summer for unconditioned telecom closets in warmer climates. Measure your worst-case ambient before assuming it clears the threshold, especially with the rack populated at high load.
- Rail kits for the 2U chassis (17.2 in W × 20 in D × 3.5 in H, 42.6 lbs) are typically sold separately by Vertiv — confirm rail compatibility with your specific rack before the equipment arrives on site. The 20-inch depth also requires a 4-post rack with at least 24 inches of usable depth.
The PSI5-1500RT120TAAN is best positioned for government and municipal security deployments — specifically TAA-restricted bids covering edge racks with NVR, managed PoE switching, and access control hardware — where the combination of TAA compliance, included RDU120 remote management, and UL 1778 listing satisfies procurement, electrical inspection, and remote monitoring requirements in a single SKU.
