TRINERGY STAKES CLAIM ON ‘MOST EFFICIENT’ UPS STATUS
The new Trinergy product set from Chloride is scalable up to 9.6MW and at a claimed 98-99% efficiency is claimed to be the most energy efficient Class 1 UPS currently available. Efficiency is achieved through a combination of operating configurations – Maximum Power Control (VFI), Maximum Energy Saving (VFD) and Power Conditioning (VI) - in the one UPS, allowing automatic monitoring of the power supply and selection of the most efficient operating mode to use only the energy required and no more. The firm claims that at that level of efficiency for a 1MW Trinergy UPS, power savings can amount to 67kW continuously per year (an estimated £100,000 based on a cost price of 10p per unit of electricity used, among other factors) and 536,000kg CO2 in equivalent savings per year. Up to 99% efficiency TUV certified, the Trinergy is claimed to offer lower running costs, is scalable up to 9.6MW (the highest active power rating available for static UPS systems) and has a unity input power factor with less than 3% THDi, resulting in more power for the same current. Use of full IGBT double conversion UPS technology provides a secure, compact system and less energy dissipation due to high efficiency reduces necessary air conditioning size and power by 400%, claims the firm.
aspect to UPS development, centring on a search for both less environmentally challenging base power supplies than lead acid and, where possible, even more renewable base energy derivation.
One major manufacturer that is trying out such new green techniques for its UPS so as to promote greater efficiencies aswell as reduce carbon footprint is AEG Power Solutions, with its Combination Architecture, which it says will use low-impact, cost- efficient technologies as sources of power or energy storage in order to increase system efficiency and reduce carbon footprint.
Maintenance is key
Power Factor Corrected loads. For smaller data centers, APC also introduced the MGE Galaxy 3500, a three-phase UPS attacking applications in the 10kVA-40kVA segment by using the double conversion online topology approach, and which also claims high efficiency – in this case up to 96%.
The MGE Galaxy 3500’s heavy-duty design of reinforced steel plates –2mmfront steel plate and NEMA 12/IP51 top plate – also protect the UPS against hard handling, dirt
and dripping liquids, and comes with easily replaceable air filters that prevent dust and debris from affecting performance. It also has dual mains input/output that allowfor connection to two separate power inputs for increased availability, busbar connections for easy connection to extended-run battery cabinets, and a soft generatorwalk- in that allows for use of a smaller generator (1.5 x UPS kVA rating).
Undeniably, there is also a green agenda
These technologies, it says, include ultracapacitors, fuel cells, solar cell and wind power energy. At this year’s CeBit, the company showed off an ultracapacitor- based UPS called the SuperCaps UPS. It claims this allows the whole or partial replacement of traditional lead acid battery banks with a more environmentally friendly solution, which provides faster recycling and eliminates the need for additional cooling.
Few details have emerged of the SuperCaps, but vendors will no doubt continue to source more efficient technologies and components for UPS. The challenge as a buyer is to ensure that any grand efficiency claims are achievable in your specific environment.
