HAH1 Family

Compact current sensor for busbar mounting +/-1200A with Redundant or Dual range capabilities (high/low range outputs). Suitable for high power battery management system and motor control applications

HAH1 - Automotive current sensors

The HAH1 family is 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 (high power) and the secondary circuit (electronic circuit).

The HAH1 family gives you the choice of having different current measuring ranges in the same housing.

While the HAH1BVW Series is dedicated to Battery Management Systems (BMS), HAH1DRW is designed for automotive motor control applications.

The HAH1 automotive current sensors are relying on the open loop hall effect principle. 
 

HAH1DRW, HAH1BVW – Features and benefits

HAH1 automotive current sensors

Features

  • Ratiometric transducer
  • Open Loop sensor using the Hall effect
  • Low voltage application
  • Unipolar +5 V DC 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 ratio-metric (in sensitivity and offset)

Main characteristics

  • Excellent accuracy
  • Very good linearity
  • Very low thermal offset drift
  • Very low thermal sensitivity drift
  • Galvanic separation
  • Non intrusive solution
  • High frequency bandwidth (HAH1DRW)

Typical applications

The HAH1BVW Series is only to be used on Battery Management Systems applications.

On the contrary, HAH1DRW can be used on several automotive motor control applications, such as:

  • Electrical Power Steering
  • Starter Generators
  • Converters
  • Battery Management
  • Motor drive application
