Chroma Model 6300 series Smart Electronic Load System is the state-of-the-art instrument for testing DC power sources and power electronic components. The system is configured by plugging the user selectable load modules into the system mainframe, and operated using the instrument front panel keypads or the remote controlled instructions via GPIB/RS-232 interface. The load modules can be programmed independently for testing multi-output DC/DC power supplies, or in parallel for testing high power application.
