Panduit UVPL12H SteadySine Lithium-Ion External Battery Pack
Overview
The Panduit UVPL12H is a 192V lithium-ion external battery pack (EBP) engineered exclusively for Panduit's SteadySine™ single-phase UPS line. Where lead-acid expansion packs add weight and floor space for every kilowatt-hour of runtime you need, this unit's lithium-ion chemistry keeps the footprint to a lean 3.4-inch, 4U profile — practical for dense rack-mount UPS deployments in telecom closets, edge compute rooms, and security infrastructure cabinets. The UVPL12H ships as a complete, ready-to-install assembly: chassis, batteries, and rack rail kit are all in the box, so there's no separate hardware order before the installation crew arrives on site.
Key Features
- 192V Lithium-Ion Bus Voltage: The 192V DC bus architecture is sized for the SteadySine 5kVA, 6kVA, and 10kVA single-phase UPS models. Running the battery string at 192V rather than a lower-voltage topology reduces bus current for a given power level, which directly translates to lower I²R losses and less heat generated in the battery cabinet — a real benefit in poorly ventilated rack environments.
- Lithium-Ion Chemistry: Li-ion cells charge faster than VRLA and hold capacity across a wider temperature range. In practice this means the UVPL12H returns to full charge significantly sooner after a discharge event — important in environments that see repeated utility interruptions, such as facilities in storm-prone regions or sites with unstable utility feeds. Li-ion also brings a longer calendar life than VRLA, which reduces the frequency of battery replacement cycles in hard-to-access rack deployments.
- 4U / 3.4-Inch Rack Height: At 86.5 mm (3.4 in) tall and 440 mm (17.3 in) wide, the UVPL12H fits a standard 19-inch rack without a side-mount adapter. Four rack units is a predictable budget when planning cabinet space for runtime expansion — you know exactly how many 4U slots you're spending per EBP before the rack layout is finalized.
- Rail Kit Included: The rack rail kit ships with the unit. There's no separate accessory order, no compatibility guessing between rail generations, and no delay waiting for mounting hardware. This matters on jobs where the UPS installation and rack build happen on the same day.
- Targeted Compatibility — No Guesswork: The UVPL12H is qualified for exactly six SteadySine UPS models: U05N11L, U06N11L, U10N11L, U05N12L, U06N12L, and U10N12L. That specificity is a feature, not a limitation — you're not buying a generic battery shelf that may or may not work. If your UPS host is on that list, the EBP will integrate correctly.
- Single-Phase Application: These UPS hosts operate on 208/240V single-phase input — common in US commercial branch-circuit environments, data center PDU feeds, and security equipment rooms. If your load is on a three-phase distribution scheme, this battery pack (and its compatible UPS hosts) are not the correct architecture; escalate to a three-phase UPS family instead.
- Package Quantity of 1: Ordered and shipped as a single unit. Runtime planning is straightforward: determine the required extended runtime at your load level, size the number of EBPs accordingly (consult the SteadySine runtime curves for the specific UPS model), and order that quantity. No partial-pack ordering complexity.
Integration & Compatibility
The UVPL12H is designed for use with the following Panduit SteadySine UPS models only — do not attempt to connect it to other UPS families or VRLA-based systems:
- U05N11L — 5kVA SteadySine single-phase lithium-ion UPS
- U06N11L — 6kVA SteadySine single-phase lithium-ion UPS
- U10N11L — 10kVA SteadySine single-phase lithium-ion UPS
- U05N12L — 5kVA SteadySine single-phase lithium-ion UPS (alternate config)
- U06N12L — 6kVA SteadySine single-phase lithium-ion UPS (alternate config)
- U10N12L — 10kVA SteadySine single-phase lithium-ion UPS (alternate config)
Battery management is handled through the host UPS — the EBP does not require independent configuration. Before integrating into an existing power distribution infrastructure, verify that the rack has open 4U space, that the cable management path from the UPS host to the EBP position is clear, and that the cabinet's weight rating accommodates the additional battery mass. Exact weight is not published in the available evidence; confirm with Panduit's technical documentation before finalizing rack load calculations.
Frequently Asked Questions
Q: Which UPS models is the UVPL12H compatible with?
A: The UVPL12H is compatible exclusively with Panduit SteadySine single-phase lithium-ion UPS models U05N11L, U06N11L, U10N11L, U05N12L, U06N12L, and U10N12L (5kVA, 6kVA, and 10kVA variants). It is not compatible with VRLA-based UPS systems or other UPS families.
Q: Does the UVPL12H include mounting hardware?
A: Yes. The UVPL12H ships with the chassis, batteries, and rack rail kit included in a single package — no separate rail or mounting hardware order is required.
Q: What is the battery bus voltage of the UVPL12H?
A: The UVPL12H operates at a 192V DC battery bus voltage, matched to the architecture of the compatible SteadySine 5/6/10kVA UPS hosts.
Q: How many rack units does the UVPL12H occupy?
A: The UVPL12H is a 4U rack-mount unit, measuring 3.4 inches (86.5 mm) in height and 17.3 inches (440 mm) in width, fitting standard 19-inch rack enclosures.
Q: Can multiple UVPL12H units be connected to a single UPS?
A: The source evidence does not specify the maximum number of EBPs supported per UPS host. Consult Panduit's SteadySine technical documentation or contact Panduit directly for multi-EBP runtime stacking limits per model.
Q: Is the UVPL12H a drop-in replacement for a VRLA battery pack?
A: No. The UVPL12H uses lithium-ion chemistry and is designed specifically for lithium-ion SteadySine UPS hosts (model numbers ending in 'L'). It is not interchangeable with VRLA battery packs and should not be used with VRLA-based UPS systems.
The UVPL12H is a tightly scoped product — it does one thing and it does it correctly: it extends the runtime of Panduit's SteadySine lithium-ion UPS family at the 5, 6, and 10kVA tier. The 192V battery bus is what makes this a closed ecosystem item; you can't swap in a generic VRLA shelf and expect the battery management system on the host UPS to accept it. If you're speccing runtime expansion for a SteadySine installation, this is the unit to quote.
Technical Highlights:
- 192V Li-Ion Architecture: Running the battery string at 192V reduces bus current at a given wattage, which cuts I²R losses and thermal load inside the cabinet — relevant in security equipment rooms where HVAC is undersized relative to the rack count.
- Chassis + Batteries + Rail Kit in One SKU: The UVPL12H ships complete. On a typical security or edge-compute rack build, the difference between 'everything in one order' and 'waiting on a back-ordered rail kit' can delay commissioning by days. This removes that variable.
- 4U / 3.4-Inch Profile: At 86.5 mm tall, this EBP is a predictable 4U spend in a 42U or 48U rack plan. If you're stacking multiple EBPs for extended runtime, you can calculate available slots before the cabinet ships.
Deployment Considerations:
- Confirm cabinet weight rating before installing — lithium-ion battery packs at this voltage class carry significant mass, and the published specs do not include a weight figure. Pull the full datasheet from Panduit before finalizing rack load calculations.
- The UVPL12H is valid only for the six 'L'-suffix SteadySine SKUs. If the host UPS on-site is a VRLA variant (no 'L' suffix), this EBP will not be compatible — verify the exact UPS model number before ordering.
This unit is the right call for any SteadySine 5–10kVA deployment where the base UPS runtime at full load is insufficient for the protected equipment's recovery time — edge security nodes, access control head-end rooms, and surveillance NVR/server racks where a 10–20 minute runtime extension makes the difference between a clean shutdown and data loss.
