LT 4000 Family

For DC, AC, pulse currents' measurements of 4000 ARMS nominal with galvanic isolation

LT 4000 - Current Sensors

The LT 4000 family comprises current sensors specifically designed for industrial applications. 

These sensors are notable for their excellent accuracy and swift response times, functioning efficiently with a dual power supply of +/- 24V.

To ensure their correct usage, it is essential to securely mount these components onto a panel. They are designed with a primary conductor crossing featuring a 102 mm diameter aperture.

LT 4000 current sensors utilize closed-loop Hall effect technology.
