General to high-performance electronic power supplies are selected based on the required current, voltage and power ratings. When an application is specialized or complex, additional device functionality will be need to be assessed. For example, you might be looking for a power supply to support communications applications or a device designed for bench testing. When reviewing a power supply for electronic testing and measurement, consider: output characteristics, control options and specialized features. Do you want manual or computer-based operations? A stand-alone unit or a modular one? Reviewable power supply characteristics can include:
