Mission-critical 5 kVA UPS

The Vertiv Liebert AS6A0NCUGNNXLKB is an online double-conversion UPS rated at 5 kVA and 4.5 kW, designed for mission-critical equipment. It accepts split-phase input voltages from 200/100 to 240/120 VAC with auto-sensing frequency between 40 Hz and 70 Hz. The unit operates in rack or tower orientation and supports scaling to 20 kVA N+1 redundancy.

Environmental sensors and monitoring

Factory-installed temperature, leak detection and humidity sensors provide continuous environmental awareness alongside the LCD status display. Hard-wired 4-wire L-L-N-G connections secure both input and output wiring for single-phase operation. User-configurable output frequency defaults to 60 Hz with 50 Hz selectable.

Five-minute full-load runtime

Valve-regulated lead-acid batteries deliver 5 minutes of runtime at full load and 15 minutes at half load. Operating temperature range spans 32°F to 104°F with humidity tolerance up to 95% non-condensing. Physical footprint measures 38" x 17" x 34" and weighs 415 lbs, requiring adequate floor or rack capacity.

Questions about this item

How often will the Valve Regulated Lead Acid batteries need replacement?

The internal VRLA cells are rated for a 5-minute full-load runtime and 15 minutes at half load; typical service life is three to five years before capacity drops below useful levels.

What limits continuous output before the unit derates or shuts down?

The 4.5 kW rating is the sustained ceiling; exceeding it triggers immediate overload protection, and the 40 °C maximum operating temperature is the thermal limit that forces derating if airflow is restricted.

How much heat and fan noise should I expect when this UPS runs 24/7 at full load?

At 4.5 kW the double-conversion modules dissipate roughly 15 % of rated power as heat, and the internal fans ramp to maintain the 40 °C internal limit, producing noticeable but data-centre-typical airflow noise.
