The main features of the system

  • The system was designed for the current flowing in both directions (from -10 to 10 A), in our offer available are also other versions.
  • A small losses of power
    • low resistance of the conductive path (0,7 mΩ)
    • the PCB is made of copper with a thickness of 70 µm
  • The current paths are isolated from a current path
    • The possibility to install anywhere
  • Work in a wide temperature range from -40 °C to 110 °C
  • Accuracy at room temperature: 1,5 %
  • Bandwidth of up to 80 kHz (reduction by using the appropriate capacitor)

The connection method of the system

The sensor requires connecting of a voltage supply from 4.5 V to 5.5 V over the fields VCC and GND. The output is analog voltage proportional to measured current (185 mV/A, centered at 2.5 V).

  • Input current (IP+ and IP-)
  • The logical power (VCC and GND)
  • Sensor's output (OUT)

FILTER pin allows you to configure the bandwidth of the board by adding a capacitor CF to ground in parallel with a capacitor of 1 nF. Without the additional filter capacitor, the transmission bandwidth is 80 kHz. More information about the impact of the external capacitor of the filter on the bandwidth, is in the catalogue's note.
