Modern power conversion systems such as photovoltaic inverters, energy-storage units, UPS systems, welding machines and motor drives place increasingly high demands on current-measurement reliability, electrical safety and installation flexibility. Engineers also face growing pressure to deploy sensors quickly and non-invasively, ideally without disconnecting conductors or interrupting running equipment. This trend drives the adoption of split-core current sensors which allow the device to be clipped around an existing cable in seconds.
German sensor specialist ChenYang Technologies has developed a practical and cost-efficient solution with its CYHCS-EXC split-core Hall Effect AC/DC current sensor. The compact housing allows it to fit into tight electrical cabinets and crowded cable bundles, while the split-core structure enables quick mounting without disconnecting conductors.
Its open-loop Hall architecture provides an output that accurately reflects the real waveform of the primary conductor without introducing insertion losses. Open-loop Hall-effect current sensing measures the magnetic field generated by the current-carrying conductor and converts it into a proportional output voltage through a Hall element and amplifier.
Located in Finsing near Munich, ChenYang is a developer of Hall Effect switching ICs, linear Hall elements, current and voltage sensors, Hall gear tooth sensors, Hall Vane sensors, Hall proximity switches, magnetoresistive speed sensors, gaussmeters, fluxmeters, magnetic pole detectors and various kinds of permanent magnetic products.
