One of the most widely discussed issues throughout the world today is the rapidly increasing price and demand of energy supply. Along with this comes the broadening awareness of the environmental impact and depletion of fossil fuels, which has created a natural drive towards energy saving and the widely encouraged use of new renewable energy sources, energy conservation best practices, and the development and advancement of energy efficient standards, processes and technologies. Where maximum uptime is paramount for many world leading organizations, the presence of a UPS is an indispensable prerequisite for a reliable power infrastructure able to achieve maximum load safeguarding and conservation.
The most common UPS topology currently used in the industry is the double conversion; nevertheless, most UPS suppliers have introduced ECO Modes of operation to further increase the levels of efficiency of the UPS. In this paper, we will analyse what the drawbacks of ECO Mode types of operation can be and we will then highlight what elements should be considered when using this mode of operation. We will then review the field results achieved by the Trinergy™ UPS. Finally, we will present the recent improvements achieved with the introduction of the Liebert® Trinergy™ Cube, which further extends the benefits made available until now through Trinergy. Liebert Trinergy Cube UPS has brought new ways of efficiency improvement to the market and has proved to be the premium UPS solution for data centers aiming to have the lowest possible PUE while maintaining the highest levels of availability.
