YNC-T4 series

Product Descriptions

The sensor series are open-loop Hall current sensors. The primary and secondary coils of the sensors are insulated, which are for controlling or measuring DC, AC and pulse currents.

Work Principles

The magnetic flux generated by the primary current aggregates in the magnetic circuit, which is detected by the Hall element in the air gap.The output voltage of the Hall element is processed, to output the standard voltage signal at the output end of the sensor. The voltage signal accurately reflects the changes of the primary current.

Wiring

 

Remarks

1. When the current to be measured flows through the input pin of a sensor, it can measure the current magnitude at the output.(Note: incorrect wiring may cause damage to the sensor).

2. The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

3. Sensors of different rated input currents and output voltages are customizable according to user needs.
