Tips: Why Do I Choose Isolated AC Current Sensor?

In electrical measurement and control scenarios, isolated AC current transducers are the preferred devices — their core value lies in adding a "safety firewall" to the system. The circuit of an ordinary transducer directly connects the measured end and the measurement and control end. Once high voltage or surge occurs in the measured circuit, the risk will be directly transmitted to the backend equipment and even the operation panel. However, isolated products, through electromagnetic or photoelectric isolation design, physically separate the front and backend. This not only avoids equipment burnout but also reduces the risk of electric shock to personnel, which is a "must-have" guarantee for both industrial and civil electrical systems.

Secondly, it can make the data "more reliable". Electromagnetic interference and common-mode noise in the electrical environment are normal. Ordinary transducers are easily "biased" by these interferences, resulting in large fluctuations in output signals, leading to inaccurate monitoring values and misjudgment of faults. In contrast, isolated transducers can filter out these clutter waves, ensuring stability and accuracy. Whether connected to an oscilloscope for waveform analysis or to a PLC for automatic control, the data can reflect the real current status.

Finally, it has friendly adaptability and maintenance costs. Such transducers usually support a wide range of primary currents, and their output standardized signals can match most measurement and control equipment, without the need for additional adapters or parameter debugging. In addition, they are small in size and easy to install on rails or with screws, so they do not take up much space during deployment. Both installation costs and operating costs are more cost-effective than ordinary equipment.
