In order to provide safety protection, the current sensors are packaged in Module packages. For protection, these current sensors are packaged in a Bulk. In this case, the maximum current supplied by the current sensors should be 25mA. It is important that current sensors do not supply more current than 25mA. To ensure that these current sensors work, the operating temperature cannot be less than 0°C. Nevertheless, the maximum operating temperature should be set to 60°C for the current sensors.
