Familiar with 277 volt? It may just be the power your data center needs.

on ‎03-31-2014 02:05 PM

Aside from the useable voltages typically seen in IT, another option exists for data centers. That option is the three-phase 480V and single-phase 277V configuration (480V/277V). This voltage provides for a staggering increase in available power.  In a modern 480V data center, the 480V is pulled through a transformer-less UPS direct to the HP 480V/277V Rackmount PDU in the rack. The HP 480V/277V Rackmount PDU is able to convert the 480V/3-phase to a 277V/single-phase circuit. This not only increases the amount of power efficiency by as much as 10 percent but also brings more than two times the power to the rack for those switching form a 120V single-phase setup to the 277V single-phase. For those looking for the big prize, switching from single phase to three-phase, the increase is a whopping 6+ times!


The HP 277V Portfolio


For datacenters looking to gain the greatest power efficiency via a 480V/277V setup, HP has a complete portfolio of rack power solutions to make the migration to 277V simple. The total solution at the rack eliminates the need for large, inefficient building power transformers in the data center to improve efficiency. The HP products available include:


HP 480V/277 Volt Rackmount PDU

277 Volt Rackmount Transformer

1200 Watt Common Slot 277 VAC Hot Plug Power Supply
