Product Description

MLG-HE2  split core Hall Effect sensors are ideal  for use in DC current applications up to 200A. For higher currents up to 1000A see our MLG-HE4 Series

The MLG-HE2  hall-effect sensor has a 4-20mA output. It is offered with uni-directional or bi-directional current measuring configurations. They are powered from + and – 15Vdc supplies. Measurlogic offered a 24Vac input, + and – 15Vdc output din rail mounting power supply module that is capable of powering up to 3 x MLG-HEx hall-effect sensors. If paired with our 1500Vdc DTS DC3 sub-meter the hall-effect power supplies are built into the DTS DC3 meter for simpler integration.
