BMS CAN Current Sensor

The EMUS CAN current sensor is a current sensor with high accuracy and has the advantage of being fully CAN controlled, so it can easily be placed at any position in a High Voltge system. In addition, the current sensor has 1 or 3 high voltage measurements, for example suitable for a pre-charge voltage measurement or extra measurements behind for example DC (CCS) contactors.
