LA 125, LA 200
For the electronic measurement of currents: DC, AC, pulsed..., with galvanic separation between the primary circuit and the secondary circuit.
LA 125, LA 200 - Current sensors
The LA 125 and LA 200 product families are closed loop hall effect current sensors designed for the DC, AC, pulse current measurement of respectively 125 and 200 Arms nominal with galvanic isolation.
LA 125 and LA 200 current sensors are to be mounted on printed circuit boards (PCB).
Their primary conductor crossing 11 x 13 mm aperture is designed for the plug crossing. These components provide excellent accuracy and good response time in industrial applications.
