HAH1 Series Automotive Current Sensors

LEM HAH1 series automotive current sensors offer electronic measurement in high-power and low-voltage automotive applications

Image of LEM HAH1 Series Automotive Current Sensors LEM HAH1 automotive current sensors are designed for the electronic measurement of DC, AC, or pulsed currents in high-power and low-voltage automotive applications with galvanic separation between the primary circuit and the secondary circuit. The HAH1 family offers the choice of having different current measuring ranges in the same housing. While the HAH1BVW series is dedicated to battery management systems, the HAH1DRW is designed for automotive motor control applications. These sensors rely on the open loop Hall effect principle and utilize busbar mounting ±1200 A with redundant or dual range capabilities.

Features
  • Open loop Hall effect
  • Unipolar +5 VDC power supply
  • Primary current measuring range ±1200 A
  • Maximum RMS primary admissible current: defined by busbar to have T <+150°C
  • Operating temperature range: -40°C < T < +125°C
  • Output voltage: full ratiometric (in sensitivity and offset)
  • Excellent accuracy
  • Very good linearity
  • Very low thermal offset and sensitivity drift
  • Galvanic separation
  • Non-intrusive solution
  • High-frequency bandwidth
Applications
  • Electrical power steering
  • Starter generators
  • Converters
  • Battery management systems
  • Motor drive applications
