了解线性电源规格

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.
