A new approach for sensors through the HOP, HTR and HT current transducers series has been introduced by LEM.
The series is based on the open loop Hall effect technology principle (allowing AC, DC and pulse current measurements). Current measurements are possible from nominal currents of 50 ARMS up to 2000 ARMS.
Their high performance, compact size, split core, high EMC immunity, isolation, ±4 V instantaneous voltage output, power supply of ±12 to 15 V form the main characteristics. Built in two parts, they can be mounted around a busbar or cable without disconnection and provide non-contact measurement of current without disruption. Simple and quick to install, they are particularly suited for retrofit use.
Applications: are for battery monitoring, AC to DC converters, telcom power distribution. All transducers are CE marked.
