3Lower Total Cost of OwnershipDC power is often associated withtelecommunications where it hasdelivered extremely high reliability fordecades. Since DC power is bothprovided by backup power sourcesand consumed by electronicequipment, a DC power architectureminimizes conversion stages from gridto chip, thus enabling higher overallefficiency with increased availability. Factory integrated system for fast andeasy site installation Service or expansion can be performedwhile the DC UPS is in operation,reducing maintenance costs Compact footprint with built-inbatteries and distribution, minimizesrequired floor space Designed for scalable growth topostpone additional capex untilcapacity is needed Energy Optimization ModeIntelligent Power Matching [Figure 1]• Achieves near-peak UPSefficiency down to 5% systemload by optimizing individualPCU performance, greatlyreducing energy costs overtime in real world conditions• Matches delivered powerfrom the UPS to real-timedemand, keeping a minimumof PCUs active and puttingthe rest on standby• Balances the run time of eachPCU by rotating the active andstandby units• Maintains the ability torespond quickly to changingload conditionsUnmatched AvailabilityResilient design System bus charges batteries anddistributes power directly to the serverrack without additional switching orconversions 65k AIC withstand rating on ACinput breaker(s) Controller outage does not interruptpower delivery to the critical load and isfield replaceable without system outageBattery monitoring technology from Albér Detects failing battery cells beforethey affect the critical load Checks each cell and associatedconnections via a proactive, patentedresistance test to reliably predictbattery performance Provides early warning of cellproblems without frequent dischargetests or battery degradation; mini-mum technician visits with maximumrun time protection SystemcontrollerstoresrawdataaccessibleviawebpageorexternalmonitoringsystemCentral to a data center’s strength is its overall uptime. To maintain business continuity,power systems must exhibit high availability and easily scale for increasing capacity.NetSure™rectifiers or power conversion units (PCUs) are the heart of the NetSure™ITM DCUPS. Each DC UPS module includes twelve independent 5.8kW PCUs. These PCUs are globallyrenowned with over 2 million units deployed, offering unmatched reliability with less than0.5% return rate (200 years MTBF). The NetSure™ITM provides many robust features to createa highly redundant package that minimizes single points of failure.

The NetSure™ITM solution is a modular system in 70 kW increments,expandable up to 280 kW (4 DC UPS modules) with one controller.Flexibility to Meet the Needs of Any Data CenterFlexible Capacity Each integrated DC UPS module occupiesonly 24 (W) x 41 (D) of floor space,including batteries and primary distribution Delivered fully configured for quick andeasy field installation Typically installed in either the middle or atthe end of a row of server racks Deploy only the capacity that is initiallyneeded; DC UPS modules can be added atany time to row configurations on the datacenter floor Choose from top and bottom cabledvariants for installation in either concreteor raised floor environmentsAs Figure 2 illustrates, the NetSure™ITMsolution starts with a primary DC UPSmodule rated for 70kW. As your powerneeds increase, you can add up to threeexpansion DC UPS modules, for a maximumcapacity of 280kW that may be configuredfor N+1 redundancy by subtracting one 6kWPCU from the rating. Each DC UPS modulealso includes 48V primary power distributionwith 22 circuit breakers (6 fuses optional).Various server rack densities are supportedwith 5-10 minutes of battery backup timeacross three parallel 48V battery strings.70kW (64kW N+1)140kW (134kW N+1)210kW (204kW N+1)280kW (274kW N+1)Figure 2: System ScalabilityFigure 2: Primary DC UPS module with 3 expansion modules (top-cabled configuration shown)Install only the capacity required; link up to four DC UPS modules to one controller Figure 3 depicts two top-cable installationscenarios. Depending on your site andbudget requirements, the NetSure™ITMsolution can either be installed as a singledeployment [Figure 3a], or incrementally byrow [Figure 3b] as power requirements grow.In either scenario, DC distribution cabling toeach rack is reduced by placing the NetSure™ITM in-the-row.Both AC and DC loads can be accommodatedat the same site. AC loads can either beprotected by an AC UPS or via a rack-mountDC to AC inverter fed from the DC UPS, bothavailable from your local Emerson NetworkPower representative.4Whatever the physical layout of your data center, the NetSure™ITM minimizes required floor space. With DC UPSbuilding block modules, you can mix and match configurationsand standard layouts to fit your available space.
