Selecting Current Sensors and Transformers: 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.
