CPD SERIES - 250 WATT

The DC input CPD250-4530 is the first in a series of hot-

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).

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

• Extra-High Current Density in Industry-Standard 3U x 8HP x

160mm Package
