The LEM HMSR-SMS series is a new generation of highly insulated, open-loop integrated current sensors designed for measuring DC and AC currents in demanding switching power applications. These sensors offer a robust, compact, and accurate solution with reinforced insulation and user-configurable overcurrent detection. Their design provides high precision and strong immunity to external fields, making them suitable for high-voltage applications. The primary conductor is designed to withstand high surge currents, and the micro magnetic core ensures immunity to external fields, ideal for power electronics with high disturbance levels. The HMSR series offers a cost-effective, small, and low-profile solution with reinforced isolation, suitable for surface-mount PCB mounting.
