LEM

A new high bandwidth (1MHz) open loop sensor capable of current sensing in some of the harshest environments has been introduced by LEM.

Digital output versions of HO and HLSR open-loop Hall effect current transducers with analogue to digital (A/D) conversion performed by an on-board sigma-delta modulator, giving a 1-bit serial bitstream output have been launched by LEM. These new components for nominal current measurements of 10, 32, 50, 80, 100, 120, 150, 200, 250 ARMS in 3 different mechanical designs (PCB and panel mounting) provide up to 12 bit resolution with 20kHz bandwidth.

LEM SA, the world’s leading manufacturer of isolated current and voltage measurement components, has appointed Alan Denny as the new Business Development Manager for its Battery Monitoring Division.

LEM has extended its range of current transducer families designed to operate from a single +5V power supply with the introduction of the HMS model. The new unit measures only 16 (L) x 13.5 (W) x 12 (H) mm and integrates a primary conductor. It is directly surface-mounted onto a printed circuit board, reducing manufacturing costs.
