詳細(xì)介紹
ds450dc ds550dc系列的和體前端電源的交流輸入同行ds550 DS450和直流輸入版本。在AC版本相同的機(jī)械，這些產(chǎn)品讓系統(tǒng)運(yùn)行于風(fēng)標(biāo)準(zhǔn)48伏直流電輸入。額定在450和550瓦的電源，DS450 / 550產(chǎn)生12伏和3.3 VD供電備用電路主直流輸出。標(biāo)準(zhǔn)功能包括有源電流共享，內(nèi)部ORing FET和存儲服務(wù)數(shù)據(jù)方便的現(xiàn)場更換EEPROM。一個(gè)I2C通信接口是為FRU EEPROM數(shù)據(jù)。
ds450dc ds550dc系列電源、容錯(cuò)和n + 1冗余的熱插拔和的應(yīng)用。
The DS450DC and DS550DC series bulk front end power supplies are the DC-input versions of their DS450 and DS550 AC-input counterparts. Mechanically identical to the AC versions, these products allow system operation from a Telco style 48 Vdc input. 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.
