Online Double Conversion
Continuously processes utility power through the rectifier and inverter before supplying the connected critical load.

Liebert S600E 20kVA UPS is a fully digital, highly reliable online double-conversion UPS designed to provide clean and consistent power for data centres, server systems, network infrastructure, automation equipment, precision instruments and other critical applications. The system delivers 20kVA and 20kW through a three-phase input and three-phase output architecture.
Liebert S600E 20kVA UPS is a fully digital, three-phase online UPS developed to protect sensitive systems from interruptions, voltage fluctuations, electrical noise, harmonics, surges and other utility-power disturbances.
The UPS provides a 20kVA rating with unity output power factor, enabling delivery of up to 20kW of active power. This makes the system suitable for modern servers, network infrastructure, automation equipment and other power-factor-corrected loads.
IGBT-based double-conversion technology continuously processes incoming AC power through the rectifier and inverter. The connected critical load therefore receives regulated output voltage and frequency during normal utility operation.
An inbuilt isolation transformer is positioned on the input side. It provides galvanic isolation within the UPS architecture and helps protect the UPS and connected equipment from significant voltage disturbances.
A wide input-voltage range allows the Liebert S600E to continue operating from utility power during unstable mains conditions. This reduces unnecessary battery use and helps preserve backup capacity.
The UPS can operate in a parallel configuration with up to four compatible units. Parallel arrangements can be used to increase available capacity or introduce N+1 system redundancy.
Integrated Ethernet, SNMP, Modbus and serial communication provide local and remote visibility of system status, alarms, measurements and recorded events.
The Liebert S600E combines digital power conversion, transformer isolation, scalable parallel operation and intelligent system monitoring.
Continuously processes utility power through the rectifier and inverter before supplying the connected critical load.
An input-side isolation transformer provides electrical separation within the UPS power path.
The 20kVA UPS can deliver 20kW of active power to modern critical electronic loads.
Up to four compatible units can operate in parallel for additional capacity or configurable N+1 redundancy.
The user interface displays measurements, power status, alarms and stored event information.
Ethernet, web, SNMP and Modbus connectivity provide remote operating and alarm visibility.
The Liebert S600E 20kVA UPS combines transformer isolation, IGBT rectification, PWM inverter technology and digital control to provide regulated power for critical loads.
The 20kVA configuration combines transformer isolation, parallel operation, configurable batteries and integrated network-management capabilities.
Battery runtime depends on the connected load, battery quantity, battery type, battery condition and operating environment.
