Product Overview
The PCS Series Current Sense Transformers are designed for efficient and accurate current monitoring in various electronic applications. Featuring surface mount technology, these transformers support frequencies up to 1 MHz and operate within a wide temperature range of -40 C to 125 C. They are ideal for use in switched-mode power supplies, motor control systems, overload sensing, and general AC current applications. The series offers models with rated primary currents up to 20 A (PCS020) and 40 A (PCS040), with robust isolation between windings.
