Panduit U10N11L SteadySine 10KVA 4U Rack-Mount Li-Ion UPS
Overview
The Panduit U10N11L is a 10 kVA rack-mount uninterruptible power supply from the SteadySine™ product family, designed for commercial and enterprise environments where clean, conditioned power is non-negotiable. At 4U tall (6.8 in / 173 mm) and 17.3 in wide, it slots into a standard 19-inch rack without consuming excessive vertical real estate — a practical consideration when rack space costs money in dense deployments. The 208/240V voltage range makes it suitable for the single-phase high-voltage circuits common in North American data centers, telecom rooms, and industrial control cabinets. The "U10N11L" model designation appears in the manufacturer's power-distribution-environmental-connectivity-hardware lineup, paired with the SteadySine™ branding that signals a pure sine wave output topology — the correct choice when your downstream load includes variable-frequency drives, active-PFC power supplies, or sensitive network equipment that rejects the modified square wave output of lower-tier UPS units.
Key Features
- 10 kVA / SteadySine™ Pure Sine Output: At 10 kVA, this unit has the headroom to protect multiple high-draw servers, network switches, or AV/security infrastructure simultaneously. Pure sine wave output matters when your loads include servers with active-PFC supplies or any equipment that specifies a sine wave source — modified wave UPS units cause those loads to run hot, fault, or shut down.
- Li-Ion Battery Technology: The "Lion" designation in the product name indicates a lithium-ion battery pack rather than conventional VRLA/AGM chemistry. Li-ion UPS batteries charge faster, last significantly longer between replacements (typically 2–3× the cycle life of lead-acid), and weigh considerably less — a real factor when rack weight budgets are tight or when the unit will be moved between sites.
- 4U Rack Form Factor (6.8 in / 173 mm): The verified height of 173 mm aligns precisely with a 4U rack profile (4 × 44.45 mm = 177.8 mm chassis + bezel). At 17.3 in wide, it mounts directly in any standard EIA 310-D 19-inch rack or cabinet. If your rack bay is already packed, measure your available U-space before ordering — 4U is a non-trivial commitment in high-density environments.
- 208/240V Voltage Range: Configured for the 208V (three-phase derived) and 240V (single-phase) circuits standard in North American commercial and light-industrial facilities. This is NOT a 120V unit — confirm your panel and PDU wiring before deployment. Mismatched input voltage is the most common installation error on UPS equipment at this power class.
- Rack-Mount / Parallel Scalability (SZ Platform): The "SZ" prefix in the product line name is consistent with Panduit's scalable UPS platform architecture, which supports parallel operation for increased capacity or redundancy. If your power protection requirements grow, adding a parallel unit avoids a full replacement — verify your specific configuration requirements with pre-sales engineering before committing.
- Commercial-Grade Power Protection: Sourced factory-new from Panduit's power-distribution line, the U10N11L is built for continuous operation in the kind of always-on environments — security operations centers, network closets, edge data rooms — where a brief power event means lost footage, failed transactions, or downed communications.
Integration and Compatibility
The U10N11L fits within Panduit's broader Panduit power distribution and infrastructure ecosystem, designed to pair with Panduit PDUs, rack cabinets, and cable management. For security and surveillance deployments, a rack-mount UPS at this power class is the correct upstream protection for network video recorders and PoE switch infrastructure — any unplanned power loss to an NVR mid-write risks filesystem corruption and footage gaps. The 208/240V input aligns with typical branch circuit configurations in commercial buildings and colocation environments. Consult a power protection planning guide to size runtime requirements against your actual load — kVA capacity and battery runtime are separate calculations, and this unit's runtime at full 10 kVA load will differ substantially from runtime at 50% load.
Frequently Asked Questions
Q: What is the form factor and rack space required for the Panduit U10N11L?
A: The U10N11L occupies 4U of rack space. Its verified dimensions are 6.8 inches (173 mm) tall and 17.3 inches (440 mm) wide, compatible with standard 19-inch EIA 310-D rack enclosures.
Q: What voltage does the U10N11L operate at?
A: The U10N11L is configured for 208/240V operation, suitable for single-phase high-voltage commercial circuits common in North American data centers and telecom rooms. It is not a 120V unit — verify your facility's circuit voltage before installation.
Q: What type of battery does the U10N11L use?
A: The U10N11L uses a lithium-ion (Li-ion) battery pack, as indicated by the "Lion" designation in the product name. Li-ion batteries offer longer service life and faster recharge times compared to conventional lead-acid VRLA batteries.
Q: Is the U10N11L a pure sine wave UPS?
A: The U10N11L belongs to Panduit's SteadySine™ product family, which designates pure sine wave output topology. Pure sine wave output is required for loads with active-PFC power supplies, variable-frequency drives, and sensitive network or AV equipment.
Q: What is the power capacity of the U10N11L?
A: The U10N11L is rated at 10 kVA, appropriate for protecting multiple high-draw servers, network switches, or security infrastructure simultaneously in a commercial rack environment.
The U10N11L sits at the serious end of the SteadySine™ rack UPS line — 10 kVA in a 4U chassis is a legitimate load anchor for a full rack of security infrastructure, and the Li-ion battery chemistry is the right call for any installation where battery replacement labor is expensive or the unit will see frequent partial-discharge cycling, as you get in SOC environments with regular grid fluctuations.
Technical Highlights:
- 10 kVA Capacity: Enough headroom to carry a fully loaded 42U security rack — NVRs, PoE switches, servers, and workstations — through a brownout or brief outage without shedding load. Size your actual load to no more than 80% of rated capacity (8 kW at unity PF) to avoid efficiency cliffs and premature battery wear.
- SteadySine™ Pure Sine Wave: Every modern server PSU with active power factor correction requires a sine wave source. Connecting an active-PFC supply to a modified-wave UPS produces audible coil whine, excess heat, and in worst cases PSU shutdown — SteadySine™ eliminates that failure mode entirely.
- 4U / 173mm Height at 440mm Width: Fits any standard 19-inch rack bay. At 6.8 inches tall, you lose 4U from your available rack space — plan your rail kit and cable management before installation, particularly if you're dropping this into a pre-populated cabinet.
Deployment Considerations:
- The 208/240V input configuration requires a correctly wired branch circuit — confirm panel voltage and circuit breaker ampacity before rack installation. A 10 kVA UPS at 208V draws approximately 48A at full load; most installations will want a 60A dedicated circuit minimum with appropriate wire gauge.
- Li-ion batteries require a compatible battery management system (BMS) — do not attempt to substitute lead-acid replacement packs. Verify any replacement battery ordering against Panduit's current approved battery list for this platform.
The U10N11L is the right anchor UPS for a security operations center or network-dense server room running on 208/240V commercial power — specifically where Li-ion's longer replacement interval reduces the operational overhead of a 10 kVA installation over a 5–7 year service window.
