magnetic system design and current measurement solutions
The module consists of a PCB including Melexis IMC- Hall® planar current sensor, CO-04-SF Clamp-On shield and the necessary components to straightfor- wardly install and operate.
Supplied with a DC voltage of 5V, the module provides a linear analog output voltage between 500 mV and 4500 mV as a function of the primary input current. Thanks to its properties, CO-04-SF-A offers an ex- cellent linearity error, below 0.5 %FS. Thanks to the integrated Melexis IMC-Hall® current sensor, the sensor module provides excellent offset as low as ±5 mV and sensitivity drift of 1 % over full temperature range.
Applications include DC and AC current sensing up to 30 kHz, motor control, battery monitoring, charge control, white goods, and many more.
