LA 306, LAC
DC, AC pulse currents' measurements of 300 ARMS to 400 ARMS nominal with galvanic isolation.
LA 306, LAC – Current Sensors
The LA 306 and LAC families closed-loop Hall effect current sensors are meticulously engineered for precise measurements of direct current (DC), alternating current (AC), and pulse currents, with nominal values ranging from 300 to 400 Arms. One significant advantage of these sensors is their ability to provide galvanic isolation, ensuring safety and accuracy in various applications.
For seamless integration into systems, both LA 306 and LAC current sensors are intended for panel mounting, featuring a primary conductor aperture measuring 30 x 13 mm.
The primary distinction between these two product families lies in their application domains. LAC is purpose-designed for railway applications, serving both fixed installations and onboard trains. In contrast, LA 306 is tailored for industrial applications, making it suitable for a wide range of industrial contexts where precise current measurement with galvanic isolation is paramount.
