Panduit U03N15L SteadySine 3KVA Uninterruptible Power Supply
Overview
The Panduit U03N15L is a 3KVA uninterruptible power supply from the Panduit SteadySine™ line, engineered for data center, edge, and enterprise multi-tenant data center (MTDC) environments where power continuity is non-negotiable. At 3U in a standard 17.3-inch wide form factor, it fits cleanly into open-frame and enclosed racks without consuming disproportionate rack space. The U03N15L operates at 208V — confirm your facility's PDU and downstream load voltage before ordering, as this is not a 120V unit.
Key Features
- SteadySine™ Output: The SteadySine sub-brand designation indicates a pure sine wave output topology. This matters when protecting switching power supplies in servers, storage arrays, and active networking gear — many of those loads are intolerant of the stepped approximation output common in line-interactive UPS units, which can cause premature PSU wear or outright incompatibility.
- 3KVA / 208V Rating: At 3KVA on a 208V input/output circuit, this unit is sized for a partial rack or a dense edge compute node — not a full high-density AI compute rack, but well-suited to a 4–8U server deployment, a network aggregation stack, or a small colocation cage. Size your load to 80% of rated capacity (2,400W effective) for thermal and battery headroom.
- Data Center and MTDC Application: Panduit positions the U03N15L explicitly for data center UPS deployments, edge nodes, and enterprise MTDC environments — meaning it's built to the reliability and serviceability expectations of those environments, not a light-commercial or office-grade spec.
- 3U Rack Form Factor (86.5mm H / 440mm W): The 3.41-inch (86.5mm) height fits a standard 2U or 3U rack slot — verify your rack's unit spacing. The 440mm width aligns with standard 19-inch rack mounting (confirm rail compatibility with your specific rack before mounting). This keeps the UPS co-located with the protected load rather than requiring a separate power shelf.
- Single-Unit Packaging: Ships as a single unit (package quantity 1), which simplifies procurement for individual rack deployments or phased rollouts — no need to break down multi-unit cases.
Integration and Compatibility
The U03N15L is part of Panduit's power distribution and environmental hardware portfolio, designed to integrate into structured data center infrastructure where rack, cable management, and power components are sourced from a single vendor ecosystem. The 208V input aligns with standard North American three-phase or split-phase data center power distribution. Pair with appropriate rack PDUs sized for 208V circuits. Verify upstream breaker sizing and confirm the runtime requirements of your specific load — 3KVA provides a finite battery reserve that should be modeled against your actual wattage draw and required bridge time to generator transfer or graceful shutdown.
Frequently Asked Questions
Q: What input voltage does the U03N15L require?
A: The U03N15L is rated for 208V operation. It is not a 120V unit — confirm your facility's power distribution supports 208V before deploying.
Q: What is the rack space requirement for the U03N15L?
A: The unit measures 3.41 inches (86.5mm) in height and 17.3 inches (440mm) in width, fitting a standard rack bay. Verify rail and mounting compatibility with your specific rack before installation.
Q: What applications is the U03N15L designed for?
A: Panduit targets the U03N15L at data center, edge compute, and enterprise multi-tenant data center (MTDC) environments — not light-commercial or office deployments.
Q: Does the U03N15L provide pure sine wave output?
A: The SteadySine™ sub-brand designation indicates a pure sine wave output topology, which is compatible with sensitive server and storage power supplies that require clean AC waveforms.
Q: How many units ship per order?
A: The U03N15L ships as a single unit (package quantity 1).
The U03N15L sits in a practical middle ground for edge and MTDC deployments: 3KVA at 208V covers a real server-and-switching stack without the footprint or cost of a larger frame UPS. The SteadySine™ designation is the spec I'd call out first — pure sine wave output is the right call for any rack with modern server PSUs or UPS-sensitive storage controllers. Running a stepped-wave unit under those loads risks shortened PSU lifespan and void-warranty scenarios with some server OEMs.
Technical Highlights:
- Pure Sine Wave (SteadySine™): Eliminates waveform compatibility issues with active PFC power supplies found in virtually all modern servers — not an optional feature, a hard requirement for this load class.
- 3KVA / 208V: Right-sized for a 4–8U compute stack or a network aggregation shelf; derate to 80% (approximately 2,400W) for safe continuous operation and adequate battery reserve.
- 3U / 440mm Wide Form Factor: At 86.5mm tall and 440mm wide, it mounts cleanly in standard 19-inch racks without a dedicated power shelf — keeps the UPS co-located with the load it protects.
Deployment Considerations:
- Confirm upstream circuit breaker sizing and PDU output voltage match 208V before racking — this unit is not field-convertible to 120V, and mismatch will damage connected equipment.
- Runtime at full 3KVA draw will be short; model your actual wattage against battery capacity and transfer-to-generator time to avoid a graceful-shutdown gap during extended outages.
The U03N15L is the right fit for a small-to-mid edge node or MTDC cage where you need rack-native 208V power protection without stepping up to a modular UPS frame — particularly when the load includes servers with active PFC supplies that demand clean sine wave input.
