Technical content

The DC input CPD250-4530 is the first in a series of hot- swap, CompactPCI® power supplies that are fully compliant to the PICMG® 2.11 Power Interface Specification using a standard Positronic 47-pin connector. Extra-high current density using innovative Power-One EDGE technology allows this unit to deliver up to 40 amperes on both the +5 and +3.3 volt outputs at 50ºC. Remote sense and active current share on the +5, +3.3 and +12 volt outputs along with ORing FETs allow these units to be used in redundant, hot-swap applications. The CPD250-4530 is feature rich, meets international safety standards, and displays the CE Mark for the Low Voltage Directive (LVD).
