The main features of the system

  • The system was designed for the current flowing in both directions (from -30 to 30 A), in our offer available are alsoother versions.
  • A small losses of power
    • low resistance of the conductive path (0,7)
    • the PCB is made of copper with a thickness of 70µm
  • 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 (66 mV/A, centered at 2.5 V).

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

FILTER pin allows youto configure the bandwidthof the board by adding a capacitorCFto 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 inthe catalogue's note.
