DS650/850DC 系列

650–850 Watt Power Supplies (48 V DC Input)

The DS650DC and DS850DC series bulk front end power supplies are the DC-input versions of their DS650 and DS850 AC-input counterparts. Mechanically identical to the AC versions, these products allow system operation from a Telco style 48 Vdc input. Rated at 650 and 850 watts respectively, the power supplies provide a choice of 12 V, 24 V or 48 V output. Each model also provides a 3.3 V or optional 5.5 V standby output. 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 FRU EEPROM data

DS650DC and DS850DC series power supplies are hot pluggable and ideal for fault tolerant and N+1 redundant applications.
