Instructions for Use:

  1. Power Supply:

    • Connect the VCC pin to a stable 5 V power supply.
    • Connect the GND pin to the ground of the power supply.
  2. Signal Output:

    • The VOUT pin provides a voltage proportional to the current being measured.
    • For a current of 0 A, the output voltage is approximately 2.5 V.
    • For positive currents, the output voltage increases above 2.5 V.
    • For negative currents, the output voltage decreases below 2.5 V.
  3. Current Sensing:

    • The primary conductor carrying the current to be measured should be passed through the center of the sensor.
    • Ensure the current does not exceed ±7 A to avoid damage or inaccurate readings.
  4. Temperature Considerations:

    • The sensor can operate over a wide temperature range (-40°C to +150°C).
    • However, extreme temperatures may affect the accuracy of the measurements.
  5. Mounting:

    • Mount the sensor on a PCB or in a suitable enclosure.
    • Ensure proper heat dissipation if operating at high temperatures.
  6. Calibration:

    • For precise applications, calibrate the sensor using known current values.
    • Adjust the sensitivity if necessary to match the expected output voltage.
  7. Electrical Isolation:

    • The sensor provides 3000 Vrms isolation between the primary conductor and the sensor circuit.
    • This ensures safety and prevents electrical interference.
  8. Storage:

    • Store the sensor in a dry, cool place away from direct sunlight and corrosive environments.
  9. Handling:

    • Handle the sensor with care to avoid damaging the pins or the internal components.
    • Use appropriate ESD protection when handling the sensor to prevent static damage.
