ds450dc ds550dc系列的和体前端电源的交流输入同行ds550 DS450和直流输入版本。在AC版本相同的机械，这些产品让系统运行于风标准48伏直流电输入。额定在450和550瓦的电源，DS450 / 550产生12伏和3.3 VD供电备用电路主直流输出。标准功能包括有源电流共享，内部ORing FET和存储服务数据方便的现场更换EEPROM。一个I2C通信接口是为FRU EEPROM数据。
ds450dc ds550dc系列电源、容错和n + 1冗余的热插拔和的应用。
The DS450DC and DS550DC series bulk front end power supplies are the DC-b versions of their DS450 and DS550 AC-b counterparts. Mechanically identical to the AC versions, these products allow system operation from a Telco style 48 Vdc b. Rated at 450 and 550 watts, the DS450/550 power supplies generate a main DC output of 12 Vdc and a 3.3 Vd for powering standby circuitry. Standard features include active current sharing, internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. An I2C communication interface is provided for the FRU EEPROM data.
DS450DC and DS550DC series power supplies are hot pluggable and ideal for fault tolerant and N+1 redundant applications.
