LEM is the world's leading manufacturer of power sensors, but also a leader in the field of power sensors.
LEM
As early as 1972, LEM company was established in Geneva, Switzerland, focusing on the development and production of the current sensor based on Hall effect and current sensors on the first streetcar for Switzerland. As the company grows, LEM Group, Switzerland Stock Exchange in 1986 and was awarded the 2nd prize at Geneva Industrial Merit.
Former secondary isolated current and voltage sensors
In today's world, in order to conserve energy and reduce costs, high efficiency, industrial products, more and more attention. Power electronics is reflected in industrial applications, such as by monitoring current, voltage and power and other parameters, its accurate adjustment to achieve optimization. LEM products using innovative technology to ensure high reliability, safety, to meet customer demand.
LEM products in the industrial area of the typical applications include:
