DHAB S/24 AUTOMOTIVE CURRENT TRANSDUCER OPEN LOOP TECHNOLOGYBattery Pack Monitoring Hybrid Vehicles EV and UtilityVehicles
1.Introduction
The DHAB family is best suited for DC, AC, or pulsed currents measurement in high power and low voltage automotive applications. It features 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).
2.Features
Open Loop transducer using the Hall effect sensor
Low voltage application
Unipolar + 5 V DC power supply
Primary current measuring range up to ± 75 A for channel 1 and ± 500 A for channel 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
3.Advantages
xcellent accuracy
Very good linearity
Very low thermal offset drift
Very low thermal sensitivity drift
Hermetic package
4.Automotive applications
Battery Pack Monitoring
Hybrid Vehicles
EV and Utility Vehicles
5.Principle of DHAB Family
The open loop transducers uses a Hall effect integrated circuit.The magnetic flux density B, contributing to the rise of the Hall voltage, is generated by the primary current IP to be measured.The current to be measured IP is supplied by a current source i.e. battery or generator (Figure 1).Within the linear region of the hysteresis cycle, B is proportional to:
B (IP) = constant (a) x IP
The Hall voltage is thus expressed by:
VH= (RH/d) x I x constant (a) x IP
Except for IP, all terms of this equation are constant.Therefore:
VH = constant (b) x IP
The measurement signal VH amplified to supply the user output voltage or current
