Keithley 2260B Series Multi-Range Switching DC Power Supplies enables sourcing of a wide range of voltages and currents(360W Model 2260B-30-36/2260B-80-13). For higher power requirements, output up to 720W with either the Model 2260B-30-72 or the Model 2260B-80-27 DC power supplies. All four instruments have constant power outputs to provide a flexible range of voltage and current output combinations. The 360W power supplies can output as much as 30V or 80V or as much as 13.5A or 36A, while the 720W power supplies can output twice as much current, 27A and 72A, with the same maximum voltage outputs. The wide range of output voltages and currents of the Series 2260B power supplies along with multiple interfaces, enable their use in numerous applications including research and design, quality control, and production testing.
