Panduit UVD048 48V VRLA Replacement Battery Cartridge Set
Overview
The Panduit UVD048 is a factory-new replacement VRLA (valve-regulated lead-acid) battery cartridge set designed for the Panduit UVP048 SteadySine™ uninterruptible power supply. When your UVP048 signals a battery end-of-life condition, the UVD048 is the direct drop-in replacement that restores full runtime without requiring UPS chassis replacement — an important cost consideration for data center and network room operators who have already invested in the UVP048 infrastructure.
VRLA chemistry means the UVD048 is sealed and maintenance-free: no electrolyte topping, no equalization cycles, no venting requirements beyond what the UVP048 chassis already provides. That makes it a straightforward swap during a planned maintenance window rather than a service event that requires specialized battery handling.
Key Features
- Direct UVP048 Compatibility: The UVD048 is engineered specifically for the Panduit UVP048 SteadySine™ UPS chassis. There is no guesswork about connector sizing, voltage matching, or runtime curve compatibility — it restores the UPS to factory-rated performance. If you are running APC RBC141 cartridges in a cross-referenced application, the UVD048 is the Panduit-native equivalent.
- 48V VRLA Chemistry: The 48V configuration supports the SteadySine pure sine wave output architecture. Pure sine wave UPS topologies are particularly relevant for active PFC power supplies (found in most modern servers, NVRs, and PoE switches) — these loads can behave erratically or fail to transfer cleanly on simulated/stepped sine wave output. Matching the correct battery voltage tier is not optional; installing the wrong voltage cartridge risks hardware damage and invalid UPS runtime calculations.
- Sealed, Maintenance-Free VRLA Design: Valve-regulated construction eliminates the need for electrolyte checks or watering. For server rooms, network closets, and equipment racks with limited access or restricted maintenance schedules, this means battery replacement is the only service event — not ongoing upkeep between replacement cycles.
- Compact Form Factor (6" W × 2.91" H): At 152.6 mm wide and 74.1 mm tall, the UVD048 slides into the UVP048 bay without requiring additional rack space. The low profile matters in dense 1U/2U rack environments where every millimeter of vertical clearance counts.
- SteadySine™ Platform Integration: The UVD048 carries the SteadySine™ sub-brand designation, meaning it is sourced and validated within the same product family as the UVP048. Using OEM battery cartridges rather than third-party alternatives preserves the UPS's battery management system calibration — third-party cells with different internal resistance or capacity curves can cause the BMS to misreport remaining runtime, which is a real operational risk in monitored environments.
- Single-Unit Packaging (Package Qty: 1): Sold as a complete cartridge set, not individual cells. This simplifies procurement and ensures the entire battery bank is refreshed simultaneously, avoiding the runtime imbalance that comes from mixing aged and new cells in the same UPS.
Integration & Compatibility
The UVD048 is specified for use with the Panduit UVP048 SteadySine™ UPS. Cross-reference to APC RBC141 is noted in the product data, which provides a reference point for integrators familiar with the APC ecosystem — however, verify fit against the Panduit UVP048 chassis before ordering if substituting in a mixed-brand deployment. For broader UPS accessories and power distribution components, confirm battery voltage and connector compatibility with your specific UPS model before procurement.
If you are building or refreshing a rack power infrastructure and need guidance on runtime budgeting, pairing the UVD048 replacement cycle with a review of your UPS battery runtime planning and rack PDU configurations is worthwhile — battery capacity is only one variable in total runtime; load wattage and PDU efficiency factor in directly.
Frequently Asked Questions
Q: What UPS is the UVD048 designed for?
A: The UVD048 is specified for use with the Panduit UVP048 SteadySine™ UPS chassis. It is the direct OEM replacement battery cartridge set for that model.
Q: What is the cross-reference for the UVD048?
A: Panduit lists the APC RBC141 as a competitor cross-reference for the UVD048. This is a reference point only — confirm physical and electrical compatibility with your specific chassis before substituting.
Q: Is the UVD048 a sealed, maintenance-free battery?
A: Yes. The UVD048 uses VRLA (valve-regulated lead-acid) chemistry, which is sealed and requires no electrolyte maintenance between replacement cycles.
Q: What are the physical dimensions of the UVD048?
A: The UVD048 measures 6 inches (152.6 mm) wide and 2.91 inches (74.1 mm) tall, designed to fit within the UVP048 battery bay.
Q: Is the UVD048 sold as a complete set or individual cells?
A: It is sold as a complete battery cartridge set (Package Qty: 1), replacing the entire battery bank in a single procurement and installation step.
Q: Why use OEM battery cartridges instead of third-party alternatives?
A: OEM cartridges like the UVD048 are validated against the UVP048 battery management system. Third-party cells with different internal resistance or capacity curves can cause the BMS to misreport remaining runtime — a meaningful risk in monitored or critical-load environments.
The UVD048 is the kind of part that only matters when you actually need it — and when you do, you want the right one on the shelf. The 48V VRLA configuration is specific to the UVP048 SteadySine™ chassis, and the compact 6" × 2.91" footprint tells you this was dimensioned to fit a defined bay, not a universal shelf slot. I've seen integrators try to bridge APC RBC141 cross-references into Panduit chassis with mixed results; the UVD048 eliminates that guesswork entirely for UVP048 operators.
Technical Highlights:
- 48V VRLA Chemistry: Matches the SteadySine™ pure sine wave output topology — critical for active PFC loads like modern servers and PoE switches that require clean sine wave transfer to avoid instability on switchover.
- OEM BMS Calibration: Installing the UVD048 preserves the UVP048's battery management system calibration. Third-party cells alter the internal resistance profile, which causes the BMS to report inaccurate runtime estimates — a silent failure mode that only surfaces during an actual outage.
- Single Cartridge Set (Package Qty: 1): The entire battery bank refreshes in one swap. Mixing aged and new cells in a multi-cell UPS degrades runtime below either cell's individual rating — whole-set replacement avoids that imbalance.
Deployment Considerations:
- Verify the UVP048 chassis is the actual installed UPS before ordering — the 48V configuration and physical dimensions (152.6 mm W × 74.1 mm H) are specific to that model and will not adapt to other SteadySine variants without chassis-level confirmation.
- The APC RBC141 cross-reference in Panduit's data is a buying-guide reference, not a confirmation of interchangeability in the other direction. Do not assume RBC141 physical dimensions match the UVD048 bay without independent verification.
For a network operations center or surveillance head-end where the UVP048 is protecting an NVR stack or core switch, the UVD048 is the correct battery refresh path — not a generic VRLA substitute. Plan replacement before the UPS BMS flags end-of-life to avoid unplanned downtime during procurement lead time.
