HMSR DA Integrated Current Sensors

LEM HMSR series represents a cutting-edge evolution in integrated current sensors that are engineered to deliver the precision of an IC with a breakthrough isolation concept for enhanced robustness. With a guaranteed isolation voltage of 4.95 kV and lab-tested performance up to 5.66 kV, the HMSR’s pre-mold design and unique footprint ensure optimal separation of the primary bar and 8 mm clearance on the landing pad. Its integrated micro core offers exceptional immunity to external magnetic fields, enabling high accuracy in demanding environments such as solar DC systems and EV chargers. Notably, the HMSR DA variant pioneers Sigma Delta bitstream output in integrated sensors, achieving up to 13 bits of effective resolution and making it an ideal solution for low-noise, high-fidelity current sensing applications.
