ACST-260 is a current sense transformer designed for AC current measurement applications with a 1:500 turns ratio. It supports a primary current range of 0.4 to 30A and operates within a frequency range of 50-200Hz, delivering an output of 37.2 mV/A ±5%. The transformer features a maximum primary resistance of 600 microohms, sense resistance of 21 Ohms ±10%, and sense inductance of 0.73H ±30%. Constructed with UL class B 130°C materials and featuring high-pot isolation of 4000V primary-to-secondary, it operates reliably across temperatures from -40°C to +70°C at full 30A rating. This component is ideal for power monitoring, energy metering, and current sensing applications requiring accurate and isolated current measurement.
