LT 100

For DC, AC, pulse currents' measurements of 100 ARMS nominal with galvanic isolation

LT 100 - Current Sensors

The LT 100 family are compact current sensors designed for traction applications.

LT 100 benefit from excellent accuracy and good response time. It is set with dual supply +/- 12 to +/- 18V.

To be used properly, these components need to be panel mounted. They come up with a 15 mm aperture diameter for the primary conductor crossing.

LT 100 current transducers are based on the closed loop Hall effect technology.
