Vertiv Liebert 20kVA UPS

The Vertiv Liebert AL4D0NHXGNNXLKB is a double-conversion online UPS rated at 20kVA and 18kW. It uses lithium-ion batteries to deliver eight minutes of runtime at full load or seventeen minutes at half load. The unit accepts three-wire 208VAC input and provides 208/120VAC split-phase output for rack or tower installations.

Check your incoming power and space

Verify that the facility supplies 200, 208, 220, 230 or 240 VAC on a three-wire L-L-G service and that the breaker can handle the 20kVA rating. Confirm the floor can support 704 lbs and that the 49 by 17 by 34 inch footprint fits the intended rack or floor area with adequate clearance for hot-swappable module access.

Thermal limits and acoustic profile

The UPS operates between 32 and 104 degrees Fahrenheit with humidity up to 95 percent non-condensing. Double-conversion topology and lithium-ion chemistry keep internal temperatures stable during normal operation. Fan speed scales with load, so noise rises under full load but remains within typical data-centre expectations for a 20kVA system.

Questions sur cet article

Does the unit ship with input cords, output receptacles or network cards, or do I need to order them separately?

The UPS is supplied as a 20 kVA / 18 kW double-conversion module with hot-swappable power, battery and control sections; input and output wiring, rack rails and any communication cards are ordered as accessories.

How do I decide between the 208 V international version and other voltage models for my 208 V three-phase service?

This model is the 208 V international version with a 3-wire L-L-G input accepting 200/208/220/230/240 VAC; choose it when the facility provides 208 V three-phase and you need 208/120 VAC split-phase output.

What does the 8-minute runtime at full load mean for a typical server rack drawing 18 kW?

At the full 18 kW rating the lithium-ion battery provides 8 minutes of backup; at half load (approximately 9 kW) the runtime extends to 17 minutes, giving time for graceful shutdown or generator start.
