Panduit U01N14L SteadySine 1KVA Lithium UPS 120V 1U Rack
Overview
The Panduit U01N14L is a 1KVA lithium-ion UPS from the Panduit SteadySine power protection line, engineered for data center racks, edge compute deployments, and enterprise micro-datacenter (MTDC) environments running 120V infrastructure. At 3.41 inches tall — a standard 1U rack height — it fits cleanly into 19-inch rack enclosures without consuming the extra 2U that older valve-regulated lead-acid (VRLA) units typically demand at this capacity. The lithium-ion chemistry is the defining design choice here: Li-Ion cells charge faster, hold a charge longer between uses, and deliver a substantially longer service life than conventional lead-acid batteries, reducing the replacement cycles that drive up total cost of ownership in always-on facilities.
The SteadySine sub-brand signals pure sine wave output — a requirement whenever protected loads include active PFC power supplies, variable-frequency drives, or sensitive networking gear. Square-wave or simulated sine wave UPS units can cause audible coil whine, excessive heat, and premature failure in modern server PSUs; the U01N14L avoids that class of problem entirely. This is the correct pick for rack UPS deployments where load equipment specifies or strongly prefers a sine wave source.
Key Features
- 1KVA Lithium-Ion Power Reserve: At 1KVA on a lithium platform, this unit supports edge compute nodes, 1U servers, network switches, or a combination of lightweight IP infrastructure at a power density that VRLA designs cannot match in the same rack footprint. Lithium cells also tolerate partial state-of-charge cycling without accelerated degradation — critical in environments where the UPS is tested frequently or experiences repeated short outages.
- Pure Sine Wave Output (SteadySine™): The SteadySine designation guarantees sinusoidal output waveform during battery operation. Modern server power supplies with active PFC regulation require a clean sine wave to operate correctly — providing square or stepped wave output risks PSU shutdown, excess heat generation, or component damage. With the U01N14L in the circuit, protected servers see grid-quality waveform even during a transfer event.
- 120V Single-Phase Input/Output: Designed for North American 120V single-phase circuits, this unit slots directly into standard facility power without step-down transformers or special branch circuit requirements. Verify your rack PDU and branch circuit breaker ratings match the 120V/1KVA draw profile when planning protected load capacity.
