What factors should be considered when selecting an industrial power supply?

Industrial switching power supplies cover the 5 to 48VDC and 15 to 1,500-W range. Typical selection criteria include the input and output voltage requirement, the amount of current, the supply must provide, and whether load current requirements change significantly under transient conditions, such as during motor start-up. Other important considerations encompass how the power supply mounts in the control cabinet and whether the application involves environmental extremes.
