Vertiv Liebert AL4A0NHUGNNXLKB 5kVA/4.5kW UPS 208V LLG in 208/120V out 8min Li-ion

Power rating and topology

The Vertiv Liebert AL4A0NHUGNNXLKB is a 5kVA/4.5kW double-conversion online UPS designed for rack or tower deployment. It accepts a 200 to 240 VAC three-wire L-L-G input and delivers 208/120 VAC output with user-configurable 50 or 60 Hz frequency. Lithium-ion batteries provide eight minutes of runtime at full load or sixteen minutes at half load.

Suitable environments and limitations

This unit suits server rooms and network closets that require continuous power conditioning and short-duration battery ride-through on a 208 V supply. It is not intended for applications needing extended backup time beyond the rated minutes or for sites that cannot accommodate a 581 lb cabinet measuring 49 by 17 by 34 inches. Buyers who need longer runtime should look at alternative solutions.

Pre-installation checks

Verify that the building electrical service can provide a 200 to 240 VAC three-wire L-L-G connection within the 40 to 70 Hz auto-sensing range. Confirm the rack or floor space can support the physical footprint and weight, and that the operating environment stays between 32 and 104 degrees Fahrenheit with zero to 95 percent non-condensing humidity. Ensure the planned load does not exceed the 4.5 kW rating.
