The Keithley 2260B-80-27 is a Programmable DC 720W Power Supply able to source a wide range of voltages and currents for higher power requirements with an output up to 720W. All four instruments have constant power outputs to provide a flexible range of voltage and current output combinations. The Keithley 2260B-80-27 720W power supply can output twice as much current, up to 27A, with the same maximum voltage outputs. The wide range of output voltages and currents of the Keithley 2260B power supplies along with multiple interfaces, enable their use in numerous applications including research and design, quality control, and production test.When more than 80V is needed, two Keithley 2260B power supplies can be connected in series to double the maximum output voltage to 160V. Similarly, up to three Keithley 2260Bs can be connected in parallel to produce as much as 216A. To combine the supplies in either series or parallel, they are controlled using a master-slave configuration. The Keithley 2260B 80 27 power supply defined as the master unit will show the total voltage and current. Thus, multiple units used in combination can deliver up to 2160W to address numerous high power applications. 

To prevent potentially dangerous inrush currents from flowing into loads that have low resistance when power is initially supplied, the Keithley 2260B power supplies have programmable rise time (or slew rate) control. Either the voltage rise time or the current rise time can be controlled. With voltage slew rate control, the voltage rise time can range from a slow 0.1V/s to a high speed of 160V/s for the 80V models. When operating under constant current control, the output current rise time can be programmed from a low slew rate of 0.01A/s to a maximum value of 144A/s. The programming of a current rise time puts the Keithley 2260B 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 undertest (DUT). In addition to controlling the rise time, the fall time can also be programmed; and the fall time values can be different from the rise time values. Thus, the delivery of power to a load can be precisely controlled to prevent overshoot spikes and excessive amounts of inrush current. This capability prevents damage to components, modules, or devices and will generate 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 Keithley 2260B-80-27 can have an internal resistance up to 5.9W to simulate devices such as a lead-acid battery. 

An internal test sequence mode allows the Keithley 2260B supplies to output a set of voltage levels for varying time intervals at each level. The test sequence can be stored and used repeatedly to deter-mine 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 current requirement such as a large inrush current. 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 on the Keithley 2260B-80-27 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.

The Keithley 2260B power supplies will work in any automated system because they can interface to a controller with either a USB, LAN, or optional GPIB interface. Additionally, the Keithley 2260B supplies have fast discharge capability to dissipate the voltage on the output quickly. The Keithley 2260B-80-27 supplies also have a fast (1ms) transient recovery time to load changes. The combination of the fast discharge time and the fast transient response helps minimize critical test time in automated test systems.

Features and Specifications of the Keithley 2260B-80-27 Power Supply includes:

  • Programmable voltage or current rise and fall times prevent damage to low impedance loads from inrush current
