The Jasper Electronics PCI254-1022-4-SSG is a 250-watt CompactPCI (cPCI) power supply engineered for industrial and embedded computing applications requiring high reliability in demanding environments. This 3U x 8HP unit delivers regulated outputs at 5.0V, 3.3V, +12.0V, and -12.0V with active power factor correction and comprehensive protection circuitry. Designed to PICMG 2.11 specifications and certified to UL/CSA, NEMKO/TUV, and CE standards, the PCI254-1022-4-SSG accepts both AC (90-264 VAC, 47-63 Hz) and DC (36-72 VDC) input power and incorporates remote sense, enable/inhibit control, and power-fail warning signaling.
