Current Sense Transformers
Current Sense Transformers are designed to detect and measure current flow in an isolated conductor or a primary winding and produce a proportional alternating current in a secondary winding. The frequency range is 2 Hz to 1 MHz with a current rating of 125 mA to 4000 A. the three types are Invasive, Non-Invasive (Solid Core), and Non-Invasive (Split Core).
Sourcing EPCOS (TDK) Current Sense Transformers: in-stock lines for quick ship, BOM matching for multi-line builds, and original-channel screening — not keyword stuffing.
