This device is a split core 1-element ac current transducer. Use the principle of electromagnetic isolation, adopts opening-closing method, easy to measure the current, isolated output the various types of standard detection and control signals. Completely isolated between input and output, good linear relationship between output signal and input signal. Can be widely used in AC current signal real-time monitoring, electricity, railways, industrial monitoring and other fields.Data Sheet
