DS650/850 系列

650–850 Watt Front End AC-DC Power Supplies

The DS650 and DS850 series of bulk front end AC-DC power supplies offers a compact 1U x 2U solution for systems with distributed power architectures. 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. DS650 and DS850 series power supplies accept a wide 90–264 Vac input and have a typical conversion efficiency of 82%. 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.
