Scalable 20 kVA Split-Phase UPS

The Vertiv Liebert AS6D0NCXGNNXLKB is a new online double-conversion UPS rated at 20 kVA and 18 kW. It accepts 120/208 V split-phase input through a 4-wire connection and auto-senses frequencies from 40 Hz to 70 Hz. Factory-installed SNMP and web card enable remote monitoring. The modular frame supports N+1 redundancy within the same 20 kVA capacity.

Suited for Critical Split-Phase Loads

This unit fits facilities that require 120/208 V split-phase power for servers, networking gear or industrial equipment. VRLA batteries deliver 5 minutes at full load and 16 minutes at half load. Buyers needing longer runtime, higher capacity or a different voltage topology should evaluate other solutions.

Rack or Tower Integration

The 38 by 17 by 34 inch chassis weighs 700 lbs and operates from 32 °F to 104 °F in 0 to 95 % non-condensing humidity. Leak, temperature and humidity sensors provide environmental awareness. LCD status indicators give local visibility. Ensure floor loading and clearance accommodate the weight and dimensions.

Questions about this item

What 4-wire input connection does the AS6D0NCXGNNXLKB require for installation?

The unit needs a 4-wire L-L-N-G feed matching one of the supported voltages such as 208/120 VAC and a 40-70 Hz source.

Will my existing 208/120 VAC split-phase loads run unchanged on the 20 kVA 18 kW output?

Yes, the UPS delivers 208/120 VAC at 60 Hz default, user-configurable to 50 Hz, so current split-phase equipment connects directly.

How do I confirm the Vertiv Liebert UPS is protecting my load after startup?

The front LCD status indicators show online double-conversion mode, output voltage, frequency, and remaining battery minutes in real time.
