The Ametek/Elgar AT8000A is a master-chassis programmable DC power system engineered as the control hub for multi-output, configurable power architectures. This mainframe integrates linear DC power supply modules and electronic DC load modules within a single 5-1/4″ rackmount chassis, with GPIB (IEEE-488) interface for remote programming and ATE integration. The system scales from single-chassis operation to 16 independent channels across multiple expansion drawers, delivering total system output up to 19.2 kW.
