LEM

LEM transducers provide control and protection signals to power converters and inverters that regulate energy both to the electric motors (for propulsion) and to the auxiliaries (for air-conditioning, heating, lighting, electrical doors, ventilators, etc).

Voltage networks vary from one country to another.

 

LEM transducers monitor them closely to ensure power electronics work accordingly.

​

Global systems for propulsion of mining trucks are similar to the ones used for diesel-electric railway locomotives. Current and voltage transducers enable inverter control which is essential for the efficient propulsion of trucks.
