Product Description

MLG-HE9  split core Hall Effect sensors are ideal  for use in DC current applications up to 500A.

The MLG-HE9 is a bi-directional sensor with a 1 Vdc output and a zero offset of 2.5Vdc.  They are powered from a single 5 Vdc supply making them simple to integrate with our DTS DC3 bi-directional DC submeters.
