The DHAB family is best suited for DC, AC, or pulsed currents measurement in high power and low voltage automotive applications. Its contains galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit).
The DHAB family gives you a choice of having different current measuring ranges in the same housing (from ± 20 up to ± 600 A).
• Open Loop transducer using the Hall effect sensor • Low voltage application • Unipolar + 5 V DC power supply • Primary current measuring range up to ± 30 A for range 1 and ± 350 A for range 2 • Maximum rms primary admissible limited by the busbar, the magnetic core or the ASIC temperature T° < + 150°C • Operating temperature range: • 40°C < T° < + 125°C • Output voltage: fully ratiometric (in sensitivity and offset) 2 measuring ranges to have a better accuracy.
Advantages • Good accuracy for high and low current range • Good linearity • Low thermal offset drift • Low thermal sensitivity drift • Hermetic package.
Applications • Battery Pack Monitoring • Hybrid Vehicles • EV and Utility Vehicles.
