Product Details

250W & 500W CompactPCI®, CPA Series

Fully compliant to the PICMG® 2.11 power interface specification using a standard Positronic 47-Pin connector
At 50°C delivers 40A on both the +5 and +3.3 volt outputs
Remote sense and active current share on the +5, +3.3 and +12 volt outputs, along with internal ORing FETs, allow these units to be used in redundant, hot-swap applications
High current density & output power in industry standard package (3U x 8HP)
Single wire active current share and remote sense on +5, +3.3, and +12V outputs
Over temperature, over current and over voltage protection
Input good and power supply fault LED indicators
Inhibit and enable inputs
Meets international safety standards and displays the CE Mark for Low Voltage Directive


250W with 400l/min forced air cooling.
Power derating above 50°C is 2.5% per °C.
