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 oper- ating 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. 40V/s APPLICATIONS 20V/s Environmental test, stress test, and accelerated life testing 10V/s LED and high power component 5V/s testing Automotive testing Battery research and test Production test Precisely control voltage rise time with the variable slew rate control.
