Select your Current Transducer

The selection of the right current sensor model for your measurement task: Are you measuring high currents in a power analyzer setup, or analyzing faster current changes in power electronics testing? The right current transducer depends on the current level, the signal speed, and the conductor size in your setup.

Use the table below to compare the main selection criteria: rated current, bandwidth, basic accuracy, and maximum conductor diameter. Checking these values help narrow down the models before checking detailed specifications and system compatibility.
