Liebert Trinergy UPS Industry’s highest operational efficiency 415/240 voltage system Systems up to 3.6 MW
– Modules up to 1200kW Unity power factor rating
– Can handle leading PF loads without de-rating State-of-the-art input and output performance
– Low Input Current Distortion, less than 3% – High Input Power Factor, 0.99 over full operating range Robust overload capability
– 125% for 10-minutes, 150% for 30-seconds
Liebert Trinergy - Dynamic Operating Modes VFI Mode - Dual Conversion: >95% efficiency Maximum Power Control - Liebert Trinergy automatically chooses this configuration whenever the electrical environment needs to be fully conditioned in order to supply the best power quality to the load.
VI Mode - Line Interactive: 96-98% efficiency High Efficiency & Power Conditioning - Liebert Trinergy automatically chooses this configuration whenever the load requires power conditioning without the need for double conversion mode, using only the necessary energy.
VFD Mode – Static Bypass: 99% efficiency Maximum Energy Saving (Digital Interactive/VFD) Liebert Trinergy automatically chooses this configuration whenever it detects that the mains energy supplied is of an ideal quality and there is no need for conditioning.
Liebert Trinergy - Modularity Horizontal & Vertical

Liebert Trinergy – Circular Redundancy Optimum energy management
when operating with partial loads provides energy cost savings in any installation where frequent variations of load occur Here’s how it works
– Special logic detects the number

–
of modules needed to supply the load while maintaining the redundancy The modules not needed work in a special standby mode that ensures the reliability of the system A special algorithm checks that each module operates in standby mode for the same amount of time
• Same ageing of modules
