Datasheet

The six models in the 850W DC power supplies in the Series 2268 provide voltage and current output levels well suited for automated test applications. They offer maximum voltage outputs of 20V, 40V, 60V, 80V, 100V, and 150V 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 both analog and digital control options and a number of 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.

• 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
