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.
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
