With space and energy conservation key topics among IT and facilities decision makers, UPS manufacturers are continually striving to design smaller products with fewer parts, lower cost, easier recycling, and less weight. This delicate balance of innovative engineering combined with supply chain component and materials selection seeks to achieve a green energy solution, facilitating improvements in recycling, energy conservation and heat management. Some UPSs now include energy-saving features such as realtime clocks (RTCs), which allow accurately timed, programmed shutdown and restart of protected devices even in the event of a power outage. Data center managers are discovering additional green advantages through the use of UPS power management software that is compatible in energy-efficient virtualized environments. Still others are reaping the rewards from new UPS topologies that can contribute significantly to greener data centers. One relatively new engineering design in power protection includes the minimally switched line-interactive (MST) UPS topology. This design abandons the use of voltage regulation transformers used in traditional line interactive topology UPSs to afford numerous advantages for users going green and saving green.
