Hall Shunt Module

Combined Hall Sensor and Shunt Current Sensor Module HSM-800

The HSM-800 is a redundant dual current sensor module combining precise Cu-Mn shunt- based current measurement and a fully redundant, galvanically isolated Hall sensor.

Product Description

The HSM-800 is a redundant dual current sensor module combining precise Cu-Mn shuntbased current measurement and a fully redundant, galvanically isolated Hall sensor. Therefore this module provides highly accurate, redundant, and reliable current measurement. Hence, it targets safety-relevant applications according to ASIL standards and ISO26262. Applications include e.g. high voltage battery monitoring, junction box, HEV, EV, and others. Additionally the module is complemented with an ambient temperature sensor allowing to determine the state-of-charge SOC, state of health SOH, and state of function SOF of modern battery-powered equipment.
