Keithley 2260B-30-72

Programmable DC Power Supply, 30V, 72A, 720W

Source a wide range of voltages and currents with the 360W, 720W, or 1080W Series 2260B Programmable DC Power Supplies. Choose from 12 versions with a voltage output of 30V, 80V, 250V or 800V. The 360W versions can output current of 36A, 13.5A, 4.5A, or 1.44A; the 720W models can output 72A, 27A, 9A, or 2.88A; and the 1080W instruments can output 108A, 40.5A, 13.5A or 4.32A. This wide range of output voltages and current, combined with multiple interface choices, makes the Series 2260B ideal for use in a wide range of applications, including research and design, quality control, and production test.

Control the Voltage or Current Rise Time to Reduce Inrush Current and Prevent Device Damage

Series 2260B power supplies have programmable rise time (or slew rate) control to prevent potentially dangerous inrush currents from flowing into loads that have low resistance when power is initially supplied. Either voltage or current rise time can be controlled. With voltage slew rate control, voltage rise time can range from a slow, 0.1V/s to a high speed of 1600V/s for the 800V supplies. When operating under constant current control, output current rise time can be programmed from a low slew rate of 0.001A/s to a maximum value of 216A/s for the Model 2260B-30-108.

Programming a current rise time puts the Series 2260B power supplies in a constant current control priority mode in which the current slew rate limits the rate at which the voltage rises across the device under test (DUT.) In addition to controlling rise time, fall time can also be programmed; fall time values can be different from rise time values. Delivery of power to a load can be precisely controlled to prevent overshoot spikes and excessive amounts of inrush current, eliminating damage to components, modules, or devices and generating more precise characteristic I-V curves for components such as LEDs.
