Description

DC Power Supplies Keithley 2268-40-21 850W 40V, 21A

Features

Six 850W models with maximum voltage outputs from 20V to 150V, maximum current outputs from 42A to 5.6A
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
