LEM offers a complete range of accurate, reliable and galvanically isolated devices for the measurement of currents from 0.1 A to 20000 A and Voltages from 10 V to 6400 V in various technologies - Open loop, Closed loop, Isolation Amplifier, etc.
LEM has been a main player in traction power electronics applications and development for the last 30 years and leverages this vast experience to supply solutions for isolated current and voltage measurements.
LEM Transducers provide control and protection signals to power converters and inverters that regulate energy to the electric motors (for propulsion) and to the auxiliaries (for air-conditioning, heating, lighting, electrical doors, ventilation, etc.). This includes the early monitoring of the voltage network to make the power electronics working accordingly.
The rail industry is under constant changes and evolution. LEM providing: the On-board monitoring of power consumption (EM4T energy meter), solutions to trackside applications, rail maintenance and the monitoring of points machines or signaling conditions with some new transducer families.
LEM is always available to assist in adapting to these evolving technical applications.
Three decades of railway experience has contributed in establishing LEM as a market leader with worldwide presence to serve you and provide efficient, safe and reliable operations of the railways.
