LA 130, LA 150

For the electronic measurement of currents: DC, AC, pulsed..., with galvanic separation between the primary circuit and the secondary circuit.

LA 130, LA 150 - Current sensors

The LA 130 and LA 150 product families consist of closed-loop hall effect current sensors tailored for measuring DC, AC, and pulse currents, with nominal values of 130 and 150 Arms, respectively, and featuring galvanic isolation.

Designed for mounting on printed circuit boards (PCB), these current transducers have a primary conductor crossing aperture of 13.5 x 10 mm, specifically designed for plug crossing. They offer excellent accuracy and rapid response times, making them well-suited for industrial applications.
