Calculate voltage drop to prevent system problems

Written on January 20, 2017 at 12:24 pm, by

One of the problems we frequently encounter in the field is that power supply users fail to take into account the voltage drop in the wires connecting a power supply to a device under test (DUT) or other electronic system. When a load draws a high current, the voltage drop across the power leads could […]

Know your power supply jargon: resolution and accuracy

Written on January 10, 2017 at 7:35 am, by

Two terms that often get bandied about when describing automated test systems are resolution and accuracy. To get the best results from your power supplies, it is important to understand the difference between these two specifications and how they affect your system. The New Oxford American Dictionary defines resolution as, “the smallest interval measurable by […]
