Selecting Current Sensors and Transformers

Nov. 7, 2022
Choosing the right current sensor does not need to be guesswork.

Current sensors are frequently used to measure and control the load current in power supplies, safety circuits and a variety of control circuits. In applications where controlling the current is required, such as in power supplies, accurately sensing the magnitude of the current is a fundamental requirement. This application note discusses selection parameters you’ll need to understand when choosing current sensors, as well as the limitations of alternative technologies such as current sense resistors.
