Application
The PEC550-12-074xD is a DC-DC CRPS module: instead of rectifying mains it steps a 48 V or 54 V rack bus down to the 12 V rail that server boards and accelerators expect. Paired with a 54 V front end such as the PEC2000 it completes an all-DC power chain for an AI rack, which is how OCP-style deployments achieve their efficiency targets. QS Compute supplies PEC550 modules for DC-bus racks and communications equipment.
