Three-phase Open Loop Current Sensor - Busbar Mounting

Piher Sensing Systems’ HCSP3BS is a three-phase open loop current sensor that generates a ratiometric analog output voltage signal proportional to the current flowing through the conductor. Based on Hall-effect technology the sensor has been designed for accurate measurement of AC and DC currents in automotive battery management and motor control applications.

  • Open loop current transducer based on Hall effect
  • Measured current values up to ±1.200 A
  • 3-phase busbar mounting
  • 3 simple analog ratiometric outputs
  • Non-intrusive technology
  • Galvanic separation between power and control
  • Full compatibility with Infineon HybridPack
  • Press fit contacts to eliminate soldering
  • Operating temperature from -40°C to +125°C
