LEM Voltage Transducers and Current Sensors
INDUSTRIAL
TRANSDUCERS
LEM transducers are present in elevators, forklifts, machines tools, printing machines and in all equipment using industrial drives on motors for efficient ... control, regulation, energy saving and comfort. Our Current sensors offer reliable and accurate measurement to enable engineers to develop systems with isolated current measurement. In Power Supplies LEM transducers ensure stable power supply accurate currents conversions depending on the various stages timely information in case of corrections or potential switching quick reactions in the event of emergency and failure, directly on the motor phases.
ENERGY AND AUTOMATION
TRANSDUCERS
Electrical signals are the power source for all manufacturing processes, machines and systems. In addition, they enable the fast and reliable supervision of ... equipment and facilities. LEM transducers take this a step further by providing your complete process with increased control and reactivity. They combine advanced sensing technologies and signal conditioning of electronic circuits (True RMS, industry standard outputs e.g. 0-5/10 V or 4-20 mA
HIGH PRECISION
TRANSDUCERS
LEM has been the leader for years in producing ultra-precise and cost-competitive transducers for both traditional and high-performance ... industrial equipment testing. They provide levels of stability and precision, in the parts per million (PPMs) of the nominal magnitude, which makes them references in calibration test benches and recognized laboratories. These Current and Voltage Sensors can measure a current all the way up from 12.5 A to 25 kA easily. They also provide an excellent accuracy at room temperature (25°C) and even at varying temperature environments.
SENSORS FOR
EV & CHARGERS
LEM works with all the major car manufacturers and Tier-1 suppliers in the world, and supplies galvanically-isolated electronic transducers that measure ... electrical parameters in battery-management and motor-control applications. The high-tech current transducers for automotive applications, thereby helping the user control the current in high-energy purposes to reduce the overall energy consumption of the vehicle, thus increasing its efficiency significantly.
TRACTION & TRACKSIDE
TRANSDUCERS
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. Managing rail networks have new requirements such as rail maintenance with the monitoring of points (switches) machines or signalling conditions. LEM transducers provide the same control and protection signals for both on-board applications and wayside substations.
CURRENT & VOLTAGE SENSORS
FOR RENEWABLE ENERGY
LEM Current sensors specifically designed for renewable power systems, control the flow and waveform of energy sent to the grid from renewable energy systems. ... They measure the current to help the windmills, solar, photovoltaic or any kind of installations to work at their maximum efficiency. The use of power electronics is a must to drive and control energy from the renewable sources in the most energy efficient way. Modern systems require precise coordination between the power semiconductors, the system controller, mechanics and the feedback sensors. Transducers provide the necessary information from the load to fulfill that function.
