Keithley 2260B-800-1 Power Supply
Programmable Dual Channel DC Power Supply: Two 800V, 1.44A, 360W
The Keithley 2260B-800-1 is a cutting-edge programmable dual channel DC power supply designed to meet the rigorous demands of laboratory and industrial applications. Featuring programmable rise time (or slew rate) control, this power supply effectively mitigates potentially damaging inrush currents when powering low-resistance loads. The rise time can be tailored either for voltage or current, with voltage slew rates adjustable from a gradual 0.1V/s to an impressive 1600V/s. When utilizing current rise time settings, the device operates in a constant current control priority mode, ensuring that current limits dictate the voltage rise across the device under test (DUT). Additionally, both rise and fall times can be independently programmed, enhancing the precision with which power is delivered to loads, significantly reducing overshoot spikes and inrush currents that could compromise sensitive components such as LEDs.
For realistic circuit testing, the Keithley 2260B-800-1 allows users to apply a test source with an output resistance that mimics the actual source, such as a battery, which typically exhibits varying internal resistance. The power supply's internal resistance can be adjusted up to 277.8Ω, accommodating a wide array of battery chemistries and load conditions. Connectivity is simplified with USB, LAN, or optional GPIB interfaces, making it compatible with any automated test system. Furthermore, the device boasts fast discharge capability to rapidly dissipate output voltage, alongside a swift, 1ms transient recovery time in response to load changes, ensuring efficiency in automated testing regimes.
An innovative internal test sequence mode allows users to program a series of voltage levels with specified time intervals for each level. This sequence is easily stored and repeatedly used to evaluate DUT performance across different voltage levels. The analog input control can replicate voltage profiles, simulating how a battery reacts to rapid current changes typical of significant inrush currents. Users can also combine DC output levels with AC signals to assess circuit responsiveness to noise on its DC power source. The flexibility of the analog input permits the creation of diverse DC supply signals for comprehensive circuit testing under varying conditions.
