Keithley 2260B-800-2 Power Supply Keithley Programmable Dual Channel DC Power Supply, Two 800V, 1.44A, 360WThe Kiethley’s 2260B-800-2 power supply has programmable rise time (or slew rate) control to prevent potentially dangerous inrush curs from flowing into loads that have low resistance when power is initially supplied. Either voltage or cur 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. Programming a cur rise time puts 2260B 800 2 in a constant cur control priority mode, in which the cur slew rate limits the rate at which the voltage rises across the device under test (DUT.) Also, controlling rise time, fall time can also be programmed; fall time values can be diffe from rise time values. Delivery of power to a load can be precisely controlled to prevent overshoot spikes and excessive amounts of inrush cur, eliminating damage to components, modules, or devices and generating more precise characteristic I-V curves for components such as LEDs.Test a circuit or device under the most realistic conditions by applying a test source with the output resistance that is equivalent to the output resistance of the actual source that will be used to power the circuit or device. For example, a battery has a varying internal resistance, and a device powered by a battery will have a voltage applied to the device that is reduced by the voltage drop across the battery’s internal resistance. The 2260B 8002 has an internal resistance of up to 277.8Ω to simulate a wide range of battery chemistries and load conditions.With their USB, LAN, or optional GPIB interfaces, Series 2260B power supplies will work in any automated system. In addition, these power supplies have an analog control capability that can control outputs via an external voltage and resistance. Furthermore, 2260B-800-2 power supplies feature fast discharge capability to quickly dissipate the voltage on the output. These power supplies also have a fast, 1ms transient recovery time to load changes. This combination of fast discharge time and fast transient response minimizes critical test time in automated test systems.An internal test sequence mode allows the 2260B-800-2 to output a set of voltage levels for varying time intervals at each level. The test sequence can be stored and used repeatedly to determine DUT performance at number of voltage levels. In addition, the analog input control can be used to create voltage profiles that simulate how a battery responds to a fast changing load cur requirement such as a large inrush cur. Also, generate a combined DC output level with an AC signal superimposed on it to test how a circuit responds to noise on its DC power source. The analog input control parameter can be either a voltage input or a resistance input. With this analog control capability, numerous types of DC supply signals can be generated to test circuits and devices under a wide range of circumstances.Features and Specifications of the Keithley 2260B-800-2 Power Supply includes:
