Description

The Vertiv Liebert EXS 30kVA is a high-density, three-phase online double-conversion uninterruptible power supply engineered to deliver clean, continuous, zero-downtime power to critical IT equipment, server rooms, medical electronics, and industrial infrastructure. Featuring a unity power factor (1.0 PF / 30kW), this transformer-free UPS supplies full active real power without derating, maximizing power availability for modern enterprise hardware.

This 0-minute autonomy configuration is specifically tailored for connection to external battery cabinets, centralized battery banks, or backup generator systems, allowing facility managers to scale backup runtime precisely to operational needs. Operating at up to 96.2% efficiency in double-conversion mode and up to 99% in ECO mode, the Liebert EXS significantly reduces power loss and cooling expenses. Built with a compact footprint, integrated manual maintenance isolation switch, parallel redundancy support (up to 4 units), and intelligent SNMP/Modbus network communication options, it ensures maximum availability for mission-critical setups.
