Customized PCB mounting current transformer
PCB current transformers (CTs) are compact, board-mountable components used to measure alternating current (AC) by stepping it down to a safer, manageable level. They are typically soldered directly onto printed circuit boards and provide essential galvanic isolation between high-voltage primary circuits and sensitive low-voltage monitoring electronics
