Automotive sensor features encrypted SPI communication
LEM has introduced a residual current monitoring (RCM) type B sensor designed for bi-directional on-board chargers (OBCs) with ASIL B capabilities. The CDT sensor addresses safety requirements in vehicle-to-everything (V2X) applications, including vehicle-to-load, vehicle-to-grid, and vehicle-to-vehicle systems. Bi-directional OBCs enable users to power other vehicles, appliances, or homes from their EV battery pack. These systems require […]
Single monitoring unit ams to extend EV range
LEM launches the new SMU family. The Single Monitoring Unit (SMU) brings previously unseen performance levels to all types of EV technologies – Full Hybrid Electric Vehicles (FHEVs), Plug-in Hybrid Electric Vehicles (PHEVs), and Battery Electric Vehicles (BEVs). The new modular SMU family meets the needs of designers of automotive battery management systems (BMS) who […]
Automotive-grade current sensors aids designers in maximizing autonomy range of EVs
One of the biggest issues in the EV sector is the need to develop vehicles that can travel the furthest possible distances between charges and so design engineers are continually searching for sensors that can offer the superior levels of efficiency and accuracy they require. The CAB 1500 is the latest member of LEM’s CAB […]
High-isolation current sensors handle overload current bursts up to 20 kA
LEM has expanded its range of miniature, integrated circuit sensors for AC and DC isolated-current measurement with the introduction of their new HMSR series. Despite being a small size, these components can handle overload current bursts up to 20 kA (8-20 µs surge test profile), such as those that occur in photovoltaics applications, while still providing a […]
Rogowski coils optimized for smart grid apps
In response to the need for improvements in electrical parameters measurement support for the expanding Smart Grid, LEM announces the development of the ARU Rogowski coils range to measure current up to 300,000 A AC with accuracy class 0.5. The ARU range achieves IEC 61869-10 class 0.5 without the need for additional components such as […]
Digital integrator for Rogowski Coils offers wide range of standard analog True RMS, instantaneous outputs
LEM introduces the AI-PMUL integrator to complete its flexible clip-around Rogowski coil offering. AI-PMUL is a versatile digital signal conditioner of Rogowski coils secondary signal which offers a wide range of standard analog True RMS and instantaneous outputs. The Rogowski coils output voltage is proportional to the derivative of primary current. An electrical integrator circuit […]
