Product Overview
The Bourns PCS Series Current Sense Transformers are designed for accurate AC current measurement in a variety of industrial applications. These surface-mount transformers offer high frequency operation up to 1 MHz and a wide operating temperature range of -40 C to 125 C. Key applications include switched-mode power supplies, motor control, overload sensing, and general AC current measurement. Available in two series, PCS020 and PCS040, they provide rated primary currents up to 20 A and 40 A respectively, with various turns ratios to suit specific needs.
