Vertiv Liebert S600 UPS Overview

Transformer-Based Online UPS for Critical Edge Power

Vertiv Liebert S600 UPS S600D is available in 10kVA and 20kVA ratings with three-phase input and single-phase output.

Fully digital double-conversion architecture continuously processes incoming power through the DC stage before recreating the AC output required by connected critical equipment.

Both S600D ratings provide unity output power factor, allowing the 10kVA unit to deliver 10kW and the 20kVA unit to deliver 20kW of active output power.

An inbuilt isolation transformer is positioned at the UPS output to provide electrical isolation within the protected power path.

The wide input-voltage and frequency windows allow the UPS to utilise utility power across substantial input variation before battery operation becomes necessary.

Online AC-AC efficiency exceeds 91%, while ECO operation exceeds 94% under applicable operating conditions.

Configurable battery quantities allow the S600D to accommodate different battery-system arrangements, with both sealed VRLA and compatible lithium-ion battery technologies.

Graphical LCD monitoring, built-in Ethernet, web-based SNMP capability and Modbus communication provide visibility into UPS operation within compatible monitoring environments.
