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
(-N) are
made from a nickel alloy core which provides the most linear response over temperature and
current level.
Nanocrystalline Amorphous (-A)
is the most versatile providing
accuracy, high saturation point and linear responses in high frequency applications. The
High Frequency
(-F) products are designed for high frequency applications such as
high frequency power supplies and motor drives.
