Understanding linear power supply specifications

September 19, 2011 // By Keithley Instruments
At first glance, a variable DC power supply appears to be a fairly simple device. However, it is a sophisticated, accurate, electrically-rugged workhorse. It must reliably deliver voltage and current that is stable, precise, and clean, no matter its load—resistive, inductive, capacitive, low impedance, high impedance, steady-state, or variable. How well the power supply fulfills this mission and where it reaches its limits are defined in its specifications. Choosing the right power supply for your application requires a good understanding of power supply specifications.
