Keithley 2260B-250-13 Power Supply
Programmable Dual Channel DC Power Supply: Two 250V, 13.5A, 1080W
The Keithley 2260B-250-13 power supply stands at the forefront of precision engineering, boasting programmable rise time control to mitigate potentially harmful inrush currents that may flow into low-resistance loads upon initial power application. Users have the flexibility to control either voltage or current rise time with this versatile unit, enhancing testing reliability.
With voltage slew rate control, voltage rise times can be adjusted from a gradual 0.1V/s up to a rapid 60V/s, offering unmatched adaptability for various testing environments. When programming a current rise time, the 2260B-250-13 transitions into a constant current control priority mode, where the current slew rate governs the voltage increase across the device under test (DUT). Moreover, users can customize fall times independently of rise times, allowing for precisely controlled power delivery to minimize overshoot spikes and excessive inrush current. This control prevents damage to sensitive components and aids in producing accurate I-V curves for devices such as LEDs.
Experience realistic battery-like testing conditions with the 2260B-250-13, which allows users to emulate the response of batteries. By applying test sources with equivalent output resistance, the internal resistance—up to 18.51Ω—simulates a variety of battery chemistries and load conditions, ensuring comprehensive evaluation of circuits and devices.
Designed with automation in mind, the Series 2260B power supplies integrate seamlessly into automated test systems through USB, LAN, or optional GPIB interfaces. Enhanced analog control capabilities allow for output management via external voltage and resistance inputs, while an impressive fast discharge feature enables swift voltage dissipation. The 1ms transient recovery time further accelerates testing efficiency, minimizing critical test durations in automated settings.
The internal test sequence mode of the Keithley 2260B-250-13 permits outputting a series of programmable voltage levels, each sustained for varying time intervals. Once created, these sequences can be stored and repeatedly utilized to analyze the DUT’s performance across multiple voltage levels. Additionally, the analog input control can simulate battery response to rapid load current changes, making it invaluable for testing scenarios involving large inrush currents. The device can also generate a combined DC output with an AC signal superimposed, allowing engineers to evaluate circuit resilience against power source noise.
