Category descriptions

DCCTs with rectangular shaped window, ideal for mounting on busbars within a switchboard, distribution board, substation, or other electrical apparatus. These DCCTs enable easy installation without the need for direct electrical contact with the busbar. This feature ensures safety and minimal disruption to the system.

Closed-Loop DCCTs incorporate a feedback loop that adjusts the magnetic field to nullify the effect of the primary current. This mechanism significantly enhances measurement accuracy, reduces the sensor’s sensitivity to external magnetic fields, and improves linearity and bandwidth. Closed-loop Hall effect sensors are widely used in applications requiring precise current control and monitoring, such as in power supplies, battery management systems, and electronic load equipment. Their ability to deliver accurate measurements even in harsh electrical environments makes them a reliable choice for critical applications.

DCCTs with built-in primary conductors are compact — It integrates the conductor directly within the device’s structure. They are particularly well-suited for use on PCBs.

DCCTs that output standardized signals that are easily integrated into industrial monitoring systems, control circuits, and data acquisition hardware. Available outputs include 0 – 20mA, 4 – 20mA, 0 – 5V, 1 – 5V, and 0 – 10V, which are widely recognized standards in automation and control industries.

AC variable speed and DC motor drives

YHDC Hall-effect isolated current sensors utilize industrial-grade Hall chips and polyurethane encapsulation, offering high control accuracy, fast response times, and excellent shock resistance, while providing multiple mounting options for AC/DC drivers.

Electric welding machine

The Hall-effect open-loop current sensor features a simple design and is encapsulated in polyurethane, offering high overload resistance. It strikes an excellent balance between performance, durability, and cost, making it ideal for use in welding machines operating in harsh environments characterized by strong electromagnetic interference, high temperatures, dust, and mechanical vibration.

Hall current sensor applications in welding machines

Inverter

Inverters/EV chargers require real-time current monitoring to precisely control switching devices, protect circuits, and maintain stable output. Hall-effect current sensors offer advantages such as electrical isolation, AC/DC measurement, and fast response. YHDC offers open-loop and closed-loop current sensors in various sizes and mounting configurations, and supports custom development.

Photovoltaic inverter applications

Medium power traction

Closed-loop current sensors utilize zero-flux technology, offering extremely fast dynamic response, minimal linear error, and low temperature drift, making them ideal for measuring currents of several hundred amperes in ultra-high-power, high-power-density SiC power modules.
