Inbuilt Isolation Transformer
An inbuilt output-side isolation transformer provides electrical isolation within the protected UPS power path.

Vertiv Liebert S600 UPS S600D is a fully digital 10kVA to 20kVA double-conversion UPS with three-phase input and single-phase output. Unity output power factor, an inbuilt isolation transformer, wide input tolerance, configurable battery options and integrated monitoring make it suitable for edge, IT, telecom and critical electrical applications.
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.
Liebert S600D combines transformer-based isolation, double conversion, configurable energy storage and digital monitoring in a compact critical-power platform.
An inbuilt output-side isolation transformer provides electrical isolation within the protected UPS power path.
Unity output power factor enables 10kW output from the 10kVA model and 20kW from the 20kVA model.
Online AC-AC efficiency exceeds 91% with the inbuilt transformer, while ECO mode exceeds 94% under applicable conditions.
Settable battery quantities and compatibility with sealed VRLA and lithium-ion battery technologies provide energy-storage flexibility.
Up to four compatible S600D UPS units can operate within a parallel power configuration.
Graphical LCD, Ethernet, SNMP, RS-232, USB and Modbus capabilities provide local and remote UPS visibility.
Vertiv Liebert S600 UPS S600D combines digital power conversion, output isolation, configurable energy storage and communication capabilities for critical edge-power applications.
The S600D 3 X 1 platform combines 10kVA and 20kVA ratings with transformer-based digital power conversion and flexible energy storage.
