Jasper Electronics CPCI354-1022-47 350 Watt cPCI Power Supply

The Jasper Electronics CPCI354-1022-47 is a 350 Watt CompactPCI power supply engineered for industrial and embedded systems requiring continuous, reliable operation. Housed in a 6U × 8HP form factor, it integrates directly into standard CompactPCI backplanes via a 47-pin PICMG connector. The unit delivers regulated outputs across four standard PCI rails - 5.0V at 40.0A, 3.3V at 40.0A, +12.0V at 9.0A, and −12.0V at 1.0A - with ripple and noise controlled to 50 mV peak-to-peak or 1% nominal maximum from DC to 20 MHz.
