Keithley 2268-20-42 Features:

  • 20V
  • 42A
  • 850W
  • Compact 1U, half-rack enclosure provides the highest power in the smallest package
  • Two auxiliary outputs support driving or signaling external devices, often eliminating the need for additional instrumentation
  • Isolated analog inputs minimize control line noise
  • Built-in LAN, USB, GPIB, RS-232, RS-485 interfaces and analog inputs are all standard
  • Constant voltage, constant current, and constant power setting control
  • Auto sequence control supports internal execution of commands to minimize bus communication time
  • Control up to 30 supplies through a single controller interface
  • Foldback mode with programmable delay shuts down the output on transitions between CV and CC operation to protect voltage- or current- sensitive devices
  • Numerous safety features protect the load and the supply, including: over-voltage and under-voltage protection, over-current protection, over- temperature protection, loop protection for multiple-supply configurations, and a hardware output interlock

The Keithley 2268-20-42 offers the highest power density in the smallest package. The Keithley 2268-20-42 is packaged in a low profile 1U high, half-rack width enclosure. This power supply takes up minimum space in a test rack. When multiple supplies are needed, these supplies can easily mount side-by-side in a test rack to provide two outputs in a 1U height space. Ventilation for the Series 2268 supplies is from the front of the instrument  to the back so additional  rack space for airflow above, below, or to the side of the supplies  is not required.  Thus, only 1U of total rack height is all that is needed. Furthermore the Series 2268 power supplies operate at temperatures up to 50°C so that they can perform reliably even in test racks that have elevated temperatures.
