400 VOLT DC POWER SOLUTIONS FOR DATA CENTERS - (PPT)

摘要

High density computer environments, utilizing Alternating Current (AC) power supply blade server technology, are presenting major challenges to owners and operators. Typical facility infrastructures cannot accommodate the added heat loads and reliability requirements of such installations. Servers equipped with Direct Current (DC) power supplies, instead of AC power supplies, operate with 20-40% less heat, reduce power consumption by up to 30%, increase server reliability, offer flexibility to installations and decrease maintenance requirements. Utilizing current off-the-shelf components, it is possible to install and operate a high reliability DC power distribution system for a DC powered server environment - without batteries or complicated AC power system drawbacks. This High Reliability DC Power Distribution System could be the next generation power system for server environments.
