CPD250-4530

CPD SERIES - 250 WATT The DC input CPD250-4530 is the first in a series of hotswap, 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® 2.11 CompactPCI® Specification • Extra-High Current Density in Industry-Standard 3U x 8HP x 160mm Package Advanced Produc t 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).
