Transformerless UPS combines flexibility with efficiency Riello UPS has launched the Sentryum (S3T), its third generation of transformerless online UPS system. Available in 10, 15, and 20kVA models, the new range puts flexibility at the forefront by offering data centre operators, IT admins and other mission-critical applications the choice of three cabinet sizes, enabling them to maximise battery backup time to suit their needs. The Compact (CPT) frame is designed for the most space-restricted environments, incorporating a single internal battery string in a footprint of less than 0.25m2. Active (ACT) houses up to two internal battery strings in a footprint of 0.35m2. While even though it takes up less than 0.4m2 space, the Xtend (XTD) option provides enough room to fit three battery strings inside its single cabinet. Manufactured using components including a dual-core DSP processor and three-level inverter, the new range delivers full-rated unity power and is capable of exceptional operating efficiency of 96.5% in double conversion online mode, even at loads of 50-75%. The Sentryum features a control system that helps minimise harmonic voltage distortion, while it also has high overload and short circuit capacity. This ensures the UPS can deal with sudden peak loads without having to transfer to bypass. Up
to eight Sentryum units can be paralleled together to scale up capacity or provide redundancy. It features a revamped large touchscreen colour display panel along with an intuitive new LED status indicator that changes colour depending on the operating mode and condition of the UPS system.
Compare costs of prefab data centres Schneider Electric has introduced a Prefabricated vs Traditional Data Centre Cost Calculator, providing users with a cost analysis for considering the best approach to deploying new IT infrastructure capacity and delivering key insights into procurement decisions. Users can also examine the effects of a combined approach, using prefabricated modules for only one, or some of the elements. Additionally, the TradeOff Tool uses trending data to devise multipliers and estimate the effects of increasing rack density, capacity and redundancy. It calculates a summary of the capital expenditure incurred via user input options and demonstrates the percentage difference. Bar charts provide a graphical overview of the equipment, design/installation and space/building costs for each approach. “Depending on the customer requirements, there are a number of advantages and disadvantages to each approach,” said Wendy Torell, senior research analyst at Schneider Electric’s Data Centre Science Centre. “With its introduction of the Prefabricated vs Traditional Data Centre Cost Calculator, Schneider Electric has simplified the task, allowing IT Professionals to model the financial implications of various deployment strategies that are accurate to within 20% or so of the costs that might be expected by choosing prefab.” Visit tinyurl.com/y2s8rbst to start using the cost comparison TradeOff Tool (schneider-electric.com) MCP October 2019
Single module, Li-ion ready UPS Piller’s newly unveiled Uniblock UBT+ 2000 UPS will be delivered VRLA and lithium-ion ready. Condensing the multiple paralleled solutions of others into a single unit, cuts cost and increases reliability in large data centre and other mission critical environments. It is highly scalable, allowing for 16 units in parallel with a total capacity of up to 32MW in one system. Furthermore, the technology allows for a complete range of system design options, from conventional low-voltage configurations to medium-voltage designs, through to the optimised efficiency and availability of leading-edge IP-bus systems able to deliver Tier III and even Tier IV compliance with simple N+1 redundancy. The Uniblock UBT+ 2000 is a high power density UPS developed from proven technology deployed across many data centres. Online efficiency ratings of 97% promise significant cost savings for operators. The capital cost per kW is reduced significantly and maintenance is kept to a minimum with its capacitor-free and parallel-free internal layout.
Real-time load data provided EkkoSense has added Rentaload load bank functionality into its EkkoSoft Critical M&E SaaS software. Customers across Europe will now be able to view real-time load data in EkkoSoft Critical, providing them with immediate insight into the impact of their real or simulated data centre loads on cooling, power and capacity performance. The solution is already in place at several data centre sites across Europe. Pierre-Luc Barbe, Rentaload’s general manager, said: “From day one we recognised the power of EkkoSoft Critical – for both real-time and simulation/risk management uses. Our customers use load banks to simulate capacity increases, and they find EkkoSoft Critical’s ability to demonstrate loads as part of their broader data centre activities a great way of optimising their risk management strategy.” missioncriticalpower.uk
