When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

Coilcraft’s new CST2020 Series current sense transformers sense current up to 40 Amps over a frequency range of 400 Hz to 1 MHz and offer 4000 Vrms isolation voltage between the sense and output ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...
