LIEBERT® NX3-PHASE UPS: 40-120KVA, 60HZ, 480VAC - SITE PLANNING DATA

The Liebert NX is a true on-line, double conversion, three-phase UPS system that delivers complete, centralized power protection for mission-critical systems.

Designed to meet the high availability power needs of a wide variety of IT applications, the UPS combines a rack form factor, advanced operating features and low cost of ownership.

Increases growth flexibility with Softscale™ technology, plus the ability to parallel modules for increased capacity and redundancy.

Achieves higher availability by reducing the number of UPS units required to power your data center.

Reduces total cost of ownership through the use of longer life batteries and simplified preventive maintenance.
