For most benchtop power supply applications, the most important feature is a user interface that allows an engineer or technician to set up the power supply quickly and easily using the front panel. Benchtop power supplies, like the Sorensen XEL Series, have this kind of interface. For example, the XEL Series has a fine control knob for setting the output voltage very accurately and an output enable switch, which lets you set up the desired voltage and current levels prior to actually turning on the output.

One of the big challenges when designing and manufacturing auto parts is ensuring that they operate reliably in very hot environments, such as Dubai, where the high temperature can easily reach 40˚C. Of course, they must also operate reliably in very cold environments, such as Siberia, where the thermometer can drop to -40˚C or below. You certainly don't want parts to fail when you're zipping down the road at 200 km/hr. because they can't take the heat (or the cold).
