1-Wire Current Sensor TSC200-15

1-Wire Interface Current Sensor Supplier

The TSC200-15 is a galvanically isolated 1-Wire current sensor that offers a cost-effective solution for monitoring both AC and DC currents. This 1-Wire sensor leverages a fully integrated Hall-effect current sensor IC, ensuring high precision and galvanic isolation. It incorporates embedded signal processing, providing a calibrated digital output.

This sensor finds applications in power monitoring scenarios, including current and power measurements for building management systems (BMS) and the supervision of batteries and solar systems, among others. Each sensor possesses a unique 64-bit serial code, enabling multiple sensors to be connected on the same 1-Wire bus. The TSC200-15 features two RJ11 connectors, facilitating easy daisy-chain wiring.
