Suitable for power distribution panels in a variety of energy management systems, the CCT series of clamp AC current sensors have been announced by TDK. Offered in two variants, rated for up to 30 and 100A, respectively, the current sensors can be quickly and easily installed in existing power distribution panels thanks to their snap-on clamp design.

The clamp AC current sensors have an integrated open-circuit protection element for voltage peak suppression and offer maximum output currents of 10 and 33.3mA for the 30 and 100A types, respectively. The CCT series has been designed for use in the power distribution panels of energy management systems (EMS) for homes, buildings and stores (HEMS, BEMS, SEMS).

Local power generation and storage are playing an ever important role in all sorts of locations and facilities. Current sensors are key components in systems for power visualisation and energy management because they enable the accurate measurement of power and thus the more efficient management of energy usage.

To manufacture the CCT series TDK has adopted the proprietary design features and automated winding and soldering techniques that were developed for the proven ZCAT series of clamp EMC components. This ensures a stable supply of high quality current sensors for manufacturers of energy management systems.
