Panduit ULC048 48V LFP Lithium Replacement Battery Card

Overview

The Panduit ULC048 is a 48V lithium iron phosphate (LFP) replacement battery card rated for 1.5 kVA UPS systems. It is engineered as a direct drop-in replacement for Panduit's U02N11L and U02S11L UPS units, allowing facilities teams and IT infrastructure managers to restore full runtime capacity without replacing the entire UPS chassis. The ULC048 also cross-references the Panduit power accessories line and directly competes with the APC RBC174-LI (APCRBC174-LI), giving you a Panduit-native LFP option where the OEM APC equivalent may otherwise be specified.

At 6.55 inches tall and 7.14 inches wide (166 mm × 181.3 mm), the ULC048 is sized to slot into the existing UPS battery bay — no structural modifications, no rewiring, no new mounting hardware. It ships as a single unit (Package Quantity: 1), so procurement is straightforward for both single-site replacements and staggered fleet refreshes across UPS accessories inventory.

Key Features

• Lithium Iron Phosphate (LFP) Chemistry: LFP cells deliver a substantially longer cycle life than VRLA/AGM alternatives — meaningful when you are managing battery replacement intervals across multiple UPS units in a data center or security infrastructure stack. Fewer replacement events reduce both labor cost and the risk of an unplanned runtime failure during a maintenance window.
• 48V System Voltage: Matches the 48V DC bus architecture of the U02N11L and U02S11L, ensuring no voltage mismatch on the battery management circuit. Deploying the wrong voltage tier is one of the most common (and damaging) battery replacement errors — the ULC048 eliminates that risk for supported units.
• 1.5 kVA Rating: Restores the full rated capacity of the host UPS. A degraded or failed lead-acid battery card in a 1.5 kVA UPS often reduces effective runtime to near zero before triggering a fault alarm — swapping to the ULC048 returns the unit to its original runtime specification.
• Compact Card Form Factor (166 mm × 181.3 mm): The card geometry — 6.55 in. H × 7.14 in. W — is designed to fit the existing battery bay without tools beyond what a standard field technician carries. This matters in rack-dense environments where adjacent equipment limits access clearance.
• Direct Cross-Reference to APCRBC174-LI: If your site was previously specifying the APC RBC174-LI equivalent, the ULC048 is the verified Panduit alternative. This is particularly useful in mixed-vendor environments where standardizing on a single battery SKU across UPS units from different OEMs is a procurement objective.
• Designed for U02N11L and U02S11L: Compatibility is explicitly scoped to these two Panduit UPS models. This is not a universal battery card — confirm your UPS model number before ordering. Deploying it in an unsupported chassis will void the UPS warranty and may cause BMS communication faults.

Integration & Compatibility

The ULC048 is confirmed compatible with the following Panduit UPS platforms:

• U02N11L — Panduit 1.5 kVA UPS (tower/rackmount)
• U02S11L — Panduit 1.5 kVA UPS variant

It cross-references to the APC APCRBC174-LI for sites sourcing equivalent LFP battery cards across a mixed UPS fleet. If you are managing a broader power distribution infrastructure, verify that the BMS protocol of each host UPS is compatible before deployment — the ULC048 communicates with the UPS management circuit natively on supported Panduit units.

For sites building out or refreshing UPS battery reserves, review the full Panduit catalog for compatible accessories, including replacement cards, PDUs, and connectivity hardware within the same power distribution ecosystem.

Frequently Asked Questions

Q: Which UPS models is the Panduit ULC048 compatible with?

A: The ULC048 is confirmed for use with the Panduit U02N11L and U02S11L UPS units. Do not install it in any other chassis without manufacturer confirmation — BMS communication errors and potential damage may result.

Q: What battery chemistry does the ULC048 use?

A: The ULC048 uses lithium iron phosphate (LFP) chemistry, which offers longer cycle life and improved thermal stability compared to traditional VRLA/AGM battery cards used in many UPS systems of this class.

Q: What is the UPS capacity this battery card is rated for?

A: The ULC048 is rated for 1.5 kVA lithium UPS systems — specifically the Panduit 1.5 kVA platform. It restores the host unit to its full rated runtime capacity when the existing battery card has degraded or failed.

Q: Does the ULC048 cross-reference to an APC battery?

A: Yes. The ULC048 is a verified cross-reference to the APCRBC174-LI (APC RBC174-LI). If your procurement spec calls out the APC part, the Panduit ULC048 is the equivalent LFP replacement within the Panduit UPS ecosystem.

Q: What are the physical dimensions of the ULC048?

A: The ULC048 measures 6.55 inches (166 mm) tall by 7.14 inches (181.3 mm) wide. Confirm bay clearance in your UPS chassis before installation, particularly in rack-mounted deployments with adjacent equipment.

Q: How many units are included per order?

A: Each order of the ULC048 includes one (1) battery card. Order quantity matches your replacement need — there is no mandatory multi-pack.

Eden Phillips

The Panduit ULC048 is a 48V LFP lithium battery card for 1.5 kVA UPS platforms — and the detail that matters most in the field is the LFP chemistry. I have watched sites go through VRLA battery card replacements on 18-24 month cycles in warm equipment rooms. LFP changes that calculus significantly, and on a card rated at this voltage tier (48V), the chemistry match to the host BMS is straightforward for the U02N11L and U02S11L.

Technical Highlights:

• 48V LFP Chemistry: LFP cells sustain higher cycle counts than VRLA/AGM alternatives — reducing replacement frequency and the risk of a silent capacity fade that only surfaces during an actual power event.
• 1.5 kVA Capacity Match: The card restores the host UPS to its full rated output. A partially degraded battery card in a 1.5 kVA unit can reduce effective runtime to minutes — the ULC048 brings it back to factory specification.
• Card Dimensions 166 mm × 181.3 mm: The physical footprint is engineered for the existing battery bay. At 6.55 in. H × 7.14 in. W, this card installs without structural modification — relevant in rack-dense rows where adjacent gear limits your working clearance.

Deployment Considerations:

• Compatibility is scoped exclusively to the U02N11L and U02S11L. Verify the UPS model tag before pulling the battery card — installing the ULC048 in an unsupported chassis risks BMS faults and warranty voidance on the host unit.
• The APC APCRBC174-LI cross-reference is useful for multi-vendor site standardization, but confirm the host UPS is a supported Panduit platform before substituting — the cross-reference is a procurement reference, not a universal fit guarantee.

The ULC048 is the right card for facilities running Panduit U02-series UPS units in security head-end rooms, telecom closets, or edge infrastructure where replacing a failed or degraded battery card on a live rack — without pulling the entire UPS — is the standard maintenance procedure.
