Keithley 2260B-30-72 30V/72A/720W Programmable DC Power Supply has 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. Programming a current rise time puts the 2260B-30-72 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.
