CAEN Universal Multichannel Power Supply Systems are 100% internally developed and designed to install into a standard 19” relay rack. The mainframes and dedicated HV/LV boards were purposefully designed to provide peak performance in a broad spectrum of operational scenarios and for a vast number of detector types. CAEN mainframe systems are modular, making upgrade and maintenance a breeze.A single mainframe may house and provide control for up to 768 independent channels. Each mainframe may be configured with a mixture of both High Voltage boards for detector bias and Low Voltage boards to drive peripheral electronics.This exceptional combination of power, flexibility, modularity, and reliability enable CAEN to customize the perfect HV/LV Mainframe System for any experimental conditions, from the smallest test-bench applications up to the largest international High Energy Physics experiments, and to do so in the most cost effective manner possible.
