Additional Details

The HTB50-TP/SP3 current transducer requires a supply voltage, typically ±12 V or ±15 V, to operate. The output signal is a current proportional to the measured primary current. An external burden resistor is usually connected to the output to convert the current signal into a voltage signal. The transducer's performance is influenced by factors such as temperature and the presence of external magnetic fields. LEM provides detailed datasheets and application notes to help designers optimize performance and ensure accurate measurements.

The galvanic isolation provided by the transducer ensures that there is no electrical connection between the primary and secondary circuits, enhancing safety and preventing ground loops. The fast response time of the transducer enables it to accurately measure rapidly changing currents, making it suitable for applications with dynamic loads. The compact size of the HTB50-TP/SP3 facilitates integration into existing systems and new designs.
