The DS650DC and 850DC modules have power output ratings of 650 and 850W respectively. The DS850DC can deliver up to 70A at +12 VDC from its main output and up to 6A from its 3.3 VDC auxiliary output. Both modules offer active single-wire current sharing which operates from 10 to 100% of full load, enabling multiple modules to be easily paralleled for very high current applications. The modules are all hot pluggable, and incorporate low-loss internal ORing FETs (Field Effect Transistors) on their main 12V output, for fault-tolerant and N+1 redundancy applications. They have no minimum load requirement, and maintain main output regulation to within ±5%.
The DC-input DS series power modules are compact, high efficiency units with a 1U x 2U form factor. They incorporate fan cooling and have an ambient operating temperature range of +10 to +45ºC, with 50% derating at +70ºC. The modules comply with all applicable EMC immunity standards, including EN61000-4-2, -3, -4, -5, -6 and -11. The power supplies carry UL/cUL60950-1 and EN60950-1 VDE safety approvals.
A built-in I²C interface allows the system to interrogate the power module to ascertain various operational parameters, including input and output status, fan blocked or running under-speed, and overcurrent and overtemperature flags.
