DHAB S/133
Key Attributes
Model Number:
DHAB S/133
Product Description
Product Overview
The LEM DHAB S/133 is an open-loop automotive current transducer utilizing Hall effect technology. It is designed for measuring DC, AC, or pulsed currents in high-power, low-voltage automotive applications such as battery pack monitoring, hybrid vehicles, and EV utility vehicles. The DHAB family offers galvanic separation between the primary and secondary circuits and provides a dual-channel sensor for wider measurement ranges (up to 900 A) and redundancy. Key advantages include good accuracy across high and low current ranges, excellent linearity, low thermal offset and sensitivity drift, and a hermetic package.
