Keithley Bench Power Supply, 0 → 40V, 21A, 1-Output, 850W

Keithley Series 2268 850W DC power supplies provide voltage and current output levels well suited for automated test applications. The six models offer maximum voltage outputs of 20V ( 852-5774 ) , 40V ( 852-5778 ), 60V ( 852-5787 ), 80V ( 852-5780 ), 100V ( 852-5784 ), and 150V ( 852-5793 ) with corresponding maximum current outputs of 42A, 21A, 14A, 10.5A, 8.5A and 5.6A. Series 2268 power supplies allow outputting any current, including the maximum current, at any voltage. They provide analog and digital control options and digital interface options, and can operate in constant voltage (CV), constant current (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. Applications include production testing, environmental testing, accelerated life testing and process control systems.

Choice of six 850W models with maximum voltage outputs from 20V (42A) to 150V (5.6A)
Compact 1U, half-rack enclosure provides the highest power in the smallest package
Two auxiliary outputs support driving or signalling external devices, often eliminating the need for additional instrumentation
Isolated analog inputs minimise control line noise
Built-in LAN, USB, GPIB, RS-232, RS-485 interfaces and analog inputs are standard
Constant voltage, constant current and constant power setting control
Auto sequence control supports internal execution of commands to minimise 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-sensitive or current-sensitive devices
Safety features include over-voltage and under-voltage protection, over-current protection, over-temperature protection, loop protection for multiple-supply configurations and a hardware output interlock
