Although power supplies are most often used in a single location, such as a design lab or a factory test station, there are times when portability is desirable. For example, you may not want to purchase a laboratory power supply with sophisticated computer-control features, such as the Sorensen XBT Series (see right), for every design engineer in your company because they may not often need those capabilities. In this case, a good strategy might be to have one that can be shared amongst the design engineers, moving it from bench to bench when needed.
Selecting a laboratory power supply for the lab is not as easy as you might think. If you thumb through a catalog and choose the first one that you think meets your needs, you could end up with a power supply that more often than not sits on the shelf. By filling out the checklist below, and comparing your needs to the product descriptions and specifications of AMETEK Programmable Power's DC bench supplies, you're more likely to get the power supply you need.
