The HMSR family is the latest range of Integrated Current Sensors by LEM. It was designed for our customers to get all the benefits from an ICS but with a new isolation concept that allows unique robustness.

HMSR allows 4.95kV guaranteed and characterized up to 5.66kV in laboratory. The family has a pre-mold design to isolate the primary bar and a special footprint to allow 8mm dCp/dCI on the landing pad. The integrated micro core inside the HMSR makes it very immune to external magnetic field and great accuracy. It is ideal for applications in solar DC side, chargers, etc.
