Vertiv AL3A0NHUGNNXLKB 5KVA/4.5KW 208V Modular UPS with Hot-Swap Battery
Overview
The Vertiv AL3A0NHUGNNXLKB is a 5KVA/4.5KW modular uninterruptible power supply designed for 3-wire (L-L-G) 208VAC distribution environments where hot-swap serviceability and scalable N+1 redundancy are non-negotiable. Built into a 42U-height, 17-inch-wide, 32-inch-deep 551 lb chassis, this unit accepts 208VAC input and delivers a split 208/120VAC output — making it a practical fit for mixed-load server rooms, data closets, and surveillance infrastructure racks that must support both 208V compute gear and 120V edge devices simultaneously. The AL3A0NHUGNNXLKB ships in a hot-swap configuration, meaning battery modules can be replaced under load without dropping connected equipment — a real operational advantage in environments that cannot tolerate scheduled maintenance windows.
The platform supports scaling to 15kVA/13.5kW in an N+1 redundant configuration, so a single chassis can grow with load demands without requiring a forklift infrastructure upgrade. Efficiency reaches up to 92%, which at sustained loads translates directly to lower heat output and reduced cooling costs in the rack or room — not a trivial consideration when this unit is sitting in a sealed IDF or compact NOC.
Key Features
- 5KVA/4.5KW per module, scalable to 15kVA/13.5kW N+1: Start with a single 5KVA module and add capacity without replacing the chassis — the N+1 ceiling means you can provision for redundancy as load grows, protecting against single-module failure at full scale.
- 208VAC input / 208-120VAC dual-voltage output: The split output handles both 208V server and storage loads and 120V ancillary devices on a single UPS — eliminates the need for separate PDUs or step-down transformers for mixed-voltage racks.
- 3-Wire (L-L-G) wiring configuration: Line-to-line-to-ground wiring aligns with standard commercial building power distribution — simplifies integration into existing panel infrastructure without custom transformer work.
- Hot-swap battery modules, 8-minute runtime: Batteries swap live under full load, so your maintenance window is whenever you schedule it — not whenever the batteries fail. The 8-minute runtime at rated load provides enough bridge time for controlled shutdowns or generator transfer in facilities without instant-start backup generation.
- Up to 92% efficiency: At 92% efficiency, heat dissipation is minimized — roughly 8% of load wattage converted to heat rather than passed to equipment. At 4.5KW continuous, that is approximately 360W of thermal load on the room, meaningfully lower than legacy ferroresonant or older double-conversion designs.
- 0°C to 40°C (32°F to 104°F) operating range: Covers standard conditioned data center and IT room environments. Not rated for unconditioned warehouse floors or outdoor enclosures — plan cooling accordingly if ambient temperatures approach the 40°C ceiling under summer loading conditions.
- 551 lb, 17W x 32D x 42H inch form factor: Floor-standing or rack-integrated depending on deployment configuration. At 551 lb, floor load and positioning logistics matter — verify raised-floor ratings or concrete slab capacity before placement.
Integration and Compatibility
The AL3A0NHUGNNXLKB targets commercial and enterprise power infrastructure running on 208VAC three-phase-derived single-phase distribution — common in co-location, campus data rooms, and mid-size enterprise server environments. The dual 208/120VAC output supports power protection for mixed-rack configurations typical in NVR and storage server deployments. For environments building out Vertiv power and cooling infrastructure, this UPS integrates within the broader Vertiv ecosystem. When sizing for a full deployment, review your rack and enclosure floor load ratings before installation — 551 lb concentrated on a single footprint requires structural verification. Consult a UPS selection guide to validate runtime, redundancy tier, and transfer time requirements against your specific load profile before committing to this form factor.
Frequently Asked Questions
Q: What is the input voltage requirement for the AL3A0NHUGNNXLKB?
A: The AL3A0NHUGNNXLKB requires 208VAC input using a 3-wire (L-L-G) wiring configuration. It is not designed for 120VAC or 240VAC single-phase residential wiring.
Q: Can the AL3A0NHUGNNXLKB support both 208V and 120V loads simultaneously?
A: Yes. The output is dual-voltage: 208VAC and 120VAC. This allows a single UPS to back up both higher-voltage server or storage equipment and standard 120V devices in the same rack environment.
Q: What is the runtime on the AL3A0NHUGNNXLKB?
A: The AL3A0NHUGNNXLKB provides approximately 8 minutes of runtime at its rated 5KVA/4.5KW load. Runtime will be longer at partial loads.
Q: Can this UPS be serviced without powering down connected equipment?
A: Yes. The AL3A0NHUGNNXLKB is configured for hot-swap battery replacement, meaning battery modules can be exchanged under live load without interrupting connected equipment.
Q: What is the maximum scalable capacity for the AL3A0NHUGNNXLKB platform?
A: The platform scales to 15kVA/13.5kW in an N+1 redundant configuration, allowing additional modules to be added to the same chassis as load requirements grow.
Q: What are the operating temperature limits for the AL3A0NHUGNNXLKB?
A: The operating temperature range is 0°C to 40°C (32°F to 104°F). It requires a conditioned indoor environment and is not rated for unconditioned or outdoor installations.
The AL3A0NHUGNNXLKB is the unit I recommend when a facility needs to start at 5KVA today but has a credible plan to reach 13.5kW within 18 months — the modular N+1 architecture means you are buying future capacity headroom, not just present-day protection. The 92% efficiency ceiling is the spec I watch most closely in high-density deployments: at 4.5KW continuous draw, you are adding roughly 360W of heat to the room, not the 500–600W you would see from older double-conversion designs at comparable loads.
Technical Highlights:
- Dual-voltage 208/120VAC output: Eliminates the need for supplemental step-down transformers in mixed racks — one UPS backs 208V servers and 120V switches or cameras from the same chassis.
- Hot-swap battery configuration: Battery replacement happens under live load; combined with an 8-minute bridge at full 5KVA, this gives field technicians enough runway to swap modules during a planned maintenance slot rather than an emergency outage.
- 551 lb, 17 x 32 x 42 inch chassis: This is not a wall-mount or shallow-depth unit — verify raised floor load ratings or slab capacity before placing it; 551 lb on a single 17-inch footprint concentrates force in a way that surprises facilities teams used to lighter modular UPS formats.
Deployment Considerations:
- The 3-wire L-L-G input wiring aligns with standard commercial panel distribution, but confirm your facility's 208VAC feed is line-to-line derived (not a 240V single-phase system) before ordering — the wiring configuration is fixed, not field-configurable.
- The 40°C upper operating limit is a hard ceiling: in a poorly ventilated IDF closet during summer peak load, ambient can breach this threshold — plan for active cooling or derate the load if ventilation is marginal.
This unit is best positioned in enterprise server rooms, campus data closets, and mid-size co-location bays where 208VAC infrastructure is already in place, mixed-voltage loads are common, and the operational team needs the flexibility to service batteries without a maintenance window requiring equipment shutdown.
