ACST-260-1 is a current sense transformer from the ACST-200 series designed for AC current sensing applications. It features a 1:500 turns ratio with an output of 37.2 mV/A ±5%, a maximum load resistance of 20 Ohms, and operates within a primary sense frequency range of 50-200Hz. The transformer is constructed with UL class B 130°C materials and offers a primary current range of 0.4 to 30A with a maximum primary resistance of 600 microohms. With a sense resistance of 21 Ohms ±10% and sense inductance of 0.73H ±30%, it provides reliable current measurement with high-pot isolation of 4000V (P-S) for 1 minute. This component is ideal for power monitoring, energy metering, and current sensing applications requiring accurate AC current measurement.
