The sensor is powered by 5 V from the MB60-16-3A battery monitor, the output voltage is proportional to the current flowing through the wire, which is inserted through a circular hole in the sensor with a Hall probe. The diameter of the hole is 22 mm. The maximum current -240 A to +560 A can be exceeded without risk of damaging the sensor. The dimensions of the sensor are 64 x 41 x 22 mm. Sensor cane be mounted to a switchboard by four holes in the corners. It is connected to the battery monitor with a four-core cable (not included).
