Charged Up and Spinning the Power
More products of recent introduction:
Three-Phase With Internal Battery
In October 2011, Eaton also rolled out its three-phase 9E power management UPS for small to medium data centers with loads ranging from 20 to 60 kVA. The UPS offers internal batteries, with up to 60 kVA, for up to 21 minutes. This internal compactness saves significant floor space—the UPS footprint alone being up to 1/3 smaller. Eaton’s 9E runs on the same software noted above and also boasts 98% energy efficiency. Combined economizing on space and energy, Eaton suggests, adds up to a lifetime savings of more than $85,000, compared with the previous-generation model.
The Diamond Plus. Also recently introduced is a modular, three-phase, double-conversion UPS from Mitsubishi Electric Power Products, Inc., called the DiamondPlus 1100. Efficiencies of up to 93.4% are reported; the UPS yields a high 0.9 output power factor; and it is lightweight, compact, upgradeable in 10-kVA increments up to 50 kVA, and configurable in N+1 from 10 kVA to 750 kVA. The Diamond Plus complements Mitsubishi’s 80-kVA to 750-kVA 9900 series. Power and battery modules are “hot swappable” for flexibility and rapid mean-time-to repair.
Green UPS Power. Powervar, Inc. (Powervar acquired Oneac from Emerson’s Chloride Division in 2011) introduced Chloride Power’s newest UPS, the CP3000NV series for medium-sized data centers with blade servers and related communications gear. It supports power level requirements from 60 to 160 kVA with a single module, or up to 960 kVA, using parallel configurations of up to six modules, the company states.
AC-AC operating efficiencies of 95% are claimed, with a “flat load/efficiency curve”, and the CP3000’s reduced heat rejection saves on cooling loads. “Green Battery Management” technology saves on power consumption through intelligent battery charging and lengthening of battery life.
Further reducing direct electrical and cooling costs is a transformer-less design, at 208/208 V and 480/480 V; the plant yields lighter weight, a smaller footprint, and faster installation.
Capacity variations are achievable by separate modules, from 60 to 80 kVA, or 100 and 120 to 160 kVA; these support three-wire in/out and four-wire in/out installations.
The UPS is also compatible with Chloride’s Connectivity Suite software. Line accessory cabinets also provide maintenance bypass functions, voltage transformation, and power distribution.
Single-Phase Metered UPS
In April 2011 Eaton introduced its 5PX UPS, aimed at small-to-medium-business data centers needing 1,000 VA (1,000 W) up to 3,000 VA (2,700 W). The 5PX is one of the first UPS on the market capable of electricity metering for each attached device. This feature enables control over individual power outlets or groups of outlets while also allowing data center managers to know, “how much power they’re consuming, to run reports and know the usage,” says an Eaton spokesperson.
The 5PX interfaces with Eaton’s Intelligent Power Software Suite, doing power monitoring; smooth shutdowns; live migration of virtual machines; LCD display; access to UPS settings; views of the power draw of each connected device; and load management. All of this is also compatible with major IT data center management software such as vCenter Server, SCVMM, KVM and Citrix Xen, and OpenSource Xen virtualization.
Whenever the 5PX indicates that connected servers are nearing maximum capacity, the system can trigger automatic relocation of virtual machines or “gracefully shutdown” servers that are connected.
