LA 200-500 SD

DC, AC pulse currents' measurements of 200 ARMS nominal with galvanic isolation

LA 200-500 SD current sensors

The LA 200-500 SD sensor family is specifically designed for the electronic measurement of DC, AC, and pulse currents while ensuring galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit).

These sensors are of the split-core type and are intended for panel mounting. They feature a 67 x 67 mm aperture for the primary conductor to pass through. The LA 200-500 SD sensor family is recognized for its excellent accuracy and rapid response time.

These current sensors are built upon closed-loop Hall effect technology, which contributes to their precision and reliability in traction current measurement applications.
