Keithley 2268-40-21 DC Power Supply  The Keithley 2268-40-21 DC power supplies offer the highest power density in the smallest package.  They provide both analog and digital control options and a number of digital interface options and can operate in constant voltage (CV), constant cur (CC), or constant power modes to address a broad array of applications. These high-efficiency, soft-starting power supplies provide reliable performance and long life. The Keithley 2268-40-21 power supplies offer users a wide range of interface options, including built-in LAN, USB, GPIB, RS-232, and RS-485 control interfaces.In addition to the main output power, the Keithely 2268-40-21 power supplies offer two auxiliary outputs, 15V output and a 5V output, for signaling and control tasks, such as to supply signals to a device handler or a test fixture control input. An auto sequence program mode gives the 2268-40-21 supplies the built-in intelligence needed to execute lists of commands. Multiple commands can be downloaded, stored in the power supply’s memory, and executed using a single command from the controller.  This ability to execute a set of commands internally saves test time by eliminating the delays involved in sending individual commands over a PC bus. Specifications for the Keithley 2268-40-21 DC Power Supply Include: See Datasheet for full specifications
