The Evolution From 12 V DC to 48 V DC Power Architecture In Data Center
Online. The Evolution From 12 V DC to 48 V DC Power Architecture In Data Center Racks And The Increasing Need For High-Density Racks.
For instance, power supply firm Advanced Energy welcomed the inclusion of 48V power shelves: "Traditionally, data center racks have used 12V power shelves, but higher performance compute and storage platforms demand more power, which results in very high current.
A primary advantage of implementing 48 V rack power architectures is the improved energy efficiency they provide. Unlike the traditional 12 V DC power distribution historically utilized in data centers, 48V systems reduce currents and minimize resistive losses throughout the rack.
By increasing the voltage to 48V, datacenters can reduce the current required to deliver the same amount of power, which significantly reduces power losses due to resistance in cables and connectors (48v-rack-power-architec). This makes 48V systems far more efficient than their 12V counterparts. 1. Lower Power Losses
(Fig. 5) As shown in this example, when the power per rack exceeds 10 kW, the power distribution loss generated by traditional 12-V DC power is said to reach an intolerable level, but a 48-V DC power supply significantly contributes to power saving for a data center.
