CR8348-2000

Current Transformers High Ratio Vertical PCB Mount Current Transformer F CR8300 SERIES CR Magnetics CR8300 Series of PCB Mounted Current Transformers are available in a wide range of sizes and materials to meet any AC current sensing needs. Our General Purpose designs are made from the highest quality silicon steel cores available, and meet most of the common AC current measurement needs. Our Revenue Grade CTs (-N) are made from a nickel alloy core which provides the most linear response over temperature and current level. The High Frequency (-F) products are designed for high frequency applications such as high frequency power supplies and motor drives. CR Magnetics offers DC Immune (-D) models that are designed to provide sensing of AC currents where DC offsets also exist. All products are offered in standard sizes, with the most popular turns ratios. UL, CSA, CE, and RoHS acceptance are all standard.
