Panduit U03N11V SteadySine Online Double-Conversion UPS, 3KVA, 120V
Overview
The Panduit U03N11V is a 3KVA online double-conversion uninterruptible power supply from the SteadySine™ line, designed for data center, edge, and enterprise micro-datacenter (MTDC) deployments running on 120V AC infrastructure. At 3.4U tall and 17.3 inches wide, it fits standard 19-inch rack enclosures without consuming excessive rack real estate — a practical consideration in edge closets where space is constrained.
Online double-conversion topology is the key distinction here. Unlike line-interactive or standby designs, the U03N11V continuously regenerates output power from its inverter regardless of utility conditions. Your connected equipment never rides on raw utility power — it runs on conditioned sine wave output at all times, with zero transfer time on utility failure. For servers, storage, and network infrastructure where even a brief power interruption causes a hard reset or data corruption, this topology is the correct choice.
The VRLA (Valve-Regulated Lead-Acid) battery chemistry is a well-established choice for rack UPS deployments — sealed, maintenance-free, and compatible with standard data center battery replacement workflows. Cross-references include the Eaton 5PX3000RTNG2, Eaton 9PX3000RTN, Liebert GXT5-3000LVRT2UXL, APC SRT3000RMXLA-NC, Minuteman UDC9603S-RT ONE, and Minuteman SU3000RTXLCD2UN, confirming this unit competes directly with the mainstream 3KVA rack UPS segment from the major power brands.
Key Features
- Online Double-Conversion Topology: Output power is continuously sourced from the inverter, not passed through from the utility. Zero transfer time on outage — no gap, no flicker — which matters for servers and active storage arrays that trip on even a 10ms interruption.
- 3KVA / SteadySine™ Capacity: At 3KVA, this covers a standard 1–2U server, a ToR switch, and patch panel draw in a typical edge node. Size your actual watt load against the derating curve before committing — manufacturers publish watt ratings separately from kVA; confirm the watt figure from the Panduit datasheet for your load calculations.
- 120V Input/Output: Matches standard North American single-phase branch circuits. No step-down transformer required; plug directly into a 120V 20A circuit typical of data center floor PDUs or NEMA L5-30 sources depending on inlet configuration.
- VRLA Battery Chemistry: Sealed, valve-regulated cells require no water topping and can be installed in any orientation without venting concerns. Standard replacement cycle for VRLA in UPS service is 3–5 years depending on thermal environment — plan battery refresh into your facility maintenance calendar.
- 2U Rack Form Factor (3.4" / 86.5mm height, 17.3" / 440mm width): Fits any standard 19-inch equipment rack. The 2U footprint is standard for this power class, leaving room for cable management above and below. Verify depth clearance in shallow-depth edge enclosures — online double-conversion chassis at this power level typically run 18–22 inches deep.
- SteadySine™ Sub-Brand Platform: Part of Panduit's broader Panduit power distribution and infrastructure line, which means accessories, extended battery modules, and network management cards are sourced from a single vendor ecosystem — useful when you're standardizing a multi-site MTDC rollout.
Integration and Compatibility
The U03N11V is positioned for data center, edge, and enterprise MTDC environments where a single vendor supplies both physical infrastructure (cabinets, PDUs, cable management) and power conditioning. If your rack deployment already uses Panduit cabinets and PDUs, this UPS integrates cleanly into that stack without introducing a second vendor's management interface.
The competitor cross-reference list (Eaton 5PX, 9PX; Liebert GXT5; APC SRT3000RMXLA-NC) confirms direct substitution compatibility at the 3KVA / 120V class. If you're replacing an end-of-life unit from one of those product families, the U03N11V is a validated drop-in candidate — verify outlet configuration and communication card compatibility against your existing network management card and monitoring infrastructure before completing the swap.
For environments running DCIM platforms or SNMP-based power monitoring, confirm the management card options available for this chassis with Panduit's pre-sales engineering team — network communication capabilities vary by configuration and are not detailed in the base SKU documentation available at time of publication.
Frequently Asked Questions
Q: What is the UPS topology of the U03N11V?
A: The U03N11V uses online double-conversion topology, meaning output power is continuously regenerated by the inverter regardless of utility conditions. Transfer time on utility failure is zero — equipment never runs on raw utility power.
Q: What battery type does the U03N11V use?
A: It uses VRLA (Valve-Regulated Lead-Acid) sealed batteries. These are maintenance-free and do not require water topping or special ventilation for standard rack installations.
Q: What rack space does the U03N11V require?
A: The unit is 3.4 inches (86.5mm) tall — a standard 2U rack footprint — and 17.3 inches (440mm) wide, fitting any 19-inch equipment rack.
Q: What competitor UPS models does the U03N11V replace?
A: Panduit lists direct cross-references to the Eaton 5PX3000RTNG2, Eaton 9PX3000RTN, Liebert GXT5-3000LVRT2UXL, APC SRT3000RMXLA-NC, Minuteman SU3000RTXLCD2UN, and Minuteman UDC9603S-RT ONE.
Q: Is the U03N11V suitable for edge deployments outside a traditional data center?
A: Yes — Panduit designates this unit for Data Center, Edge, and Enterprise MTDC applications. The 2U form factor and 120V input make it practical for IT closets and edge nodes on standard branch circuits.
Q: Does the U03N11V support external battery modules for extended runtime?
A: External battery module compatibility is not confirmed in the available base SKU documentation. Contact Panduit or a pre-sales engineer to confirm extended runtime options for this chassis.
The U03N11V sits in a specific sweet spot: 3KVA online double-conversion at 120V in a 2U chassis, positioned explicitly for edge and MTDC environments where Panduit is already supplying the physical rack infrastructure. That combination — same-vendor cabinet, PDU, and now UPS — reduces sourcing complexity on multi-site rollouts, which is a real operational argument beyond just the specs.
Technical Highlights:
- Online Double-Conversion: Zero transfer time on utility failure. For 1U/2U servers and active storage, this is the only topology worth specifying — standby and line-interactive introduce a transfer gap that causes hard resets on sensitive loads.
- VRLA Battery Chemistry: Sealed, maintenance-free cells in a 2U chassis means no special ventilation requirements and no scheduled water service. Plan for a 3–5 year battery replacement cycle as part of your facility PM schedule.
- 2U / 17.3-inch (440mm) Width: Standard 19-inch rack mount at 3.4 inches tall. Verify chassis depth against your enclosure's usable depth before ordering — online double-conversion units at this power class commonly exceed 18 inches and can conflict with shallow-depth edge cabinets.
Deployment Considerations:
- Cross-references confirm this is a direct replacement candidate for Eaton 5PX3000RTNG2, 9PX3000RTN, Liebert GXT5-3000LVRT2UXL, and APC SRT3000RMXLA-NC. If you're mid-life on one of those families, verify outlet count and communication card compatibility before committing to the swap.
- Watt output (as distinct from the 3KVA VA rating) is not published in the available documentation. Run your actual load calculation against the confirmed watt figure from Panduit's datasheet — VA ratings at 0.9 power factor yield ~2,700W, but confirm before sizing branch circuits and runtime estimates.
For a Panduit-standardized edge node or MTDC deployment — where the cabinet, cable management, and PDU are already Panduit — the U03N11V is a logical consolidation of the power protection layer under the same vendor and support channel.
