Pulse Electronics AEC-Q200 Current Sense Transformers provide a low-loss method for sensing AC current in a circuit. The transformers provide electrical and safety isolation between the source of the current, which can be connected to high voltage signals, and the measurement circuit, which is typically low voltage digital signals. Current sense magnetics are designed for switch-mode power supplies where frequencies are typically in the range of 40kHz to several MHz. Pulse Electronics AEC-Q200 Current Sense Transformers offer a 4A to 40A sensing range, isolation voltages from 500V to 5kV, and insulation systems that include functional, basic, and reinforced. These transformers are designed for switch-mode power applications.
