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 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.
**850W in the Most Compact Package**
The Series 2268 supplies offer the highest power density in the smallest package. The Series 2268 supplies are packaged in a low profile 1U high, half-rack width enclosure. These supplies take 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.
**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 currentsensitive devices
