BSTBC300LTHA Series Closed Loop Mode Hall Effect Current

 

The BSTBC-LTHA Series Hall Effect Current Sensor from WuXi Liou Electronics Co., Ltd. is a high-precision, closed-loop (magnetic balance) sensor designed for accurate measurement of DC, AC, and pulsed currents. Utilizing a Hall effect mechanism with galvanic isolation, this sensor ensures excellent linearity, fast response time, and high immunity to external interference. It supports rated inputs of 100A, 200A, and 300A with a wide measuring range up to 750A, offering output signals of up to 150mA. With no insertion losses and low temperature drift, the BSTBC-LTHA is ideal for applications in photovoltaic systems, inverters, variable speed drives, battery-powered equipment, and uninterruptible or switched-mode power supplies. It complies with international standards such as IEC61010-1, EN50178, and RoHS, ensuring safe and reliable performance in demanding environments.

Instructions

1.Incorrect wiring may cause the damage of sensor.

2.When the measured current through the center hole of the sensor, the current will be measured at the output end.

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

4.User can adjust the output extent of sensor if necessary.

5.Rated input current and output voltage of sensor can be customized.
