Product Description
Product Overview
The Bel Fuse/Signal SCS Series is a line of high-frequency Surface Mount Current Sensing Transformers designed for detecting current flow within an application's conductor. These non-invasive components accurately sense current in power supply circuits, safety circuits, and control circuits. They offer a cost-effective, low-loss method for measuring currents in high-frequency voltage regulators and switch-mode power supplies. Applications include feedback control, overload sensing, motor control, and load drop/shutdown detection. Custom versions are available upon request.Product Attributes
