CPD SERIES - 250 WATT
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.
FEATURES
•
Wide Input Range (36-75 VDC)
•
Delivers 40A for the +5V and +3.3V Outputs (No Restrictions)
•
Single-wire Current Share on Outputs V1, V2, and V3
•
Remote Sense on Outputs V1, V2, and V3
•
Overtemperature, Overvoltage, and Overcurrent Protection
•
Input Good and Power Fail LED Indicators
•
Power Fail and Temperature Warning Signals
•
Inhibit and Enable Inputs
•
Fully Compliant to PICMG

Release
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).
