High Ratio Vertical PCB Mount Current Transformer
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.
