The PCI500-4D is a modular, 500 watt, quad output power supply with wide range 48VDC input. This hot-swap supply is designed specifically for redundant applications with active current sharing on the 5V and 3.3V outputs. The PCI500 incorporates a unique architecture that supports migration of 5V requirements to 3.3V by deriving both of these outputs from a common winding on the main transformer. The PCI500 is also ideal for networking equipment, communications and computer equipment where fault-tolerance is a necessity. An AC-input counterpart is available as the PCI500-4A. All outputs have remote sense and are individually protected against overloads and short circuits. With UL/cUL approval to UL1950, VDE approval to EN60950, and CE Mark, the PCI500 provides a truly global power solution for your CompactPCI requirements.
