Product Specification
| Description | Current Sensors RoHS | Mfr. Part # | DHAB S/124 |
| Model Number | DHAB S/124 |
The LEM DHAB S/124 is an open-loop Hall effect current transducer designed for DC, AC, or pulsed current measurements in high-power, low-voltage automotive applications. It offers galvanic separation between the primary and secondary circuits and provides a dual-channel sensor for wider measurement range and redundancy. Key advantages include good accuracy across high and low current ranges, good linearity, low thermal offset and sensitivity drift, and a hermetic package.
