  • Page 22: Construction And Function

    General description The power supplies of the PSB 10000 4U series are so-called bidirectional devices, incorporating the function of a laboratory power supply (source) and an electronic load (sink) into one unit. They allow for easy setup of applications according to the source-sink principle with a minimum of required hardware and cabling.
