Current Sense Transformers
Current Sense Transformers are magnetic components used to detect, monitor and measure current in electronic and electrical systems. They provide isolation between the primary current path and sensing circuitry, making them suitable for power monitoring, overload detection, feedback control and protection functions. They are widely used in power supplies, motor drives, industrial control equipment, energy meters, inverters, battery systems, communication equipment and embedded applications.
This category includes current transformers, current sensing transformers, AC current sense transformers, PCB current transformers, split-core current transformers and related magnetic sensing components. These products are commonly selected based on current range, turns ratio, frequency range, isolation voltage, accuracy, burden resistance, mounting type, package style and application requirements.
TomatoElec supplies original Current Sense Transformers from recognized manufacturers such as Pulse Electronics, Bourns, Würth Elektronik, TDK, Murata, Triad Magnetics, Coilcraft, Hammond Manufacturing and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
