问题是直流电源并无单一标准,因此拥有不同卖家设备的数据中心很难做到这样的能源节约。
The problem is that there is no single standard for DC power supplies, so such savings cannot easily be achieved in a data centre filled with equipment from different vendors.
修订后的标准名称为《电力系统直流电源柜订货技术条件》。
The standard name after editing is "ark of power system direct current source orders goods technical condition".
