CPA SERIES - 250 WATT The AC input CPA250-4530 is a hot-swap, CompactPCI® power supply which is fully compliant to the PICMG® 2.11 Power Interface Specification using a standard Positronic 47-pin connector. Extra-high current density using innovative PowerOne EDGE technology allows this unit to deliver up to 40 amperes on both the +5 and +3.3 volt outputs at 50ºC. 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 CPA250-4530 is feature rich, meets international safety standards, and displays the CE Mark for the Low Voltage Directive (LVD). FEATURES • Wide Input Range (85-264 VAC) • 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 AC INPUT MODEL SELECTION CHART MODEL OUTPUT VOLTAGE ADJUSTMENT RANGE OUTPUT CURRENT LINE REGULATION LOAD REGULATION RIPPLE & NOISE %pk-pk (NOTE 1) CPA250-4530 +5V +3.3V +12V -12V N/A N/A N/A N/A 40A 40A 5.5A 1.5A 0.5% 0.5% 0.5% 0.5% 1% 1% 1% 1% 2% 2% 1.3% 1.3% NOTES: 1) Maximum peak-to-peak expressed as a percentage of output voltage, 20 MHz bandwidth.
