HMSR series - LEM
The HMSR is a new generation of high insulated Integrated Current Sensor from LEM. These product family provides a robust, compact and very accurate solution for measuring DC and AC currents in all highly demanding, switching power applications for commercial, industrial. HMSR is a micro core based open loop sensor with a reinforced insulation and overcurrent detections (user configurable and factory set). These features make the device suitable for high voltage applications requiring high precision and strong immunity against external field. The primary conductor (pins 1 and 8) has very low electrical resistance and dedicated pads d
